Reinforced Type features enhanced ceramic formulation with 30% higher mechanical strength and better thermal shock resistance, ideal for high-power and heavy-duty cutting. Gold-Plated Type has a gold-plated electrode and surface that provides superior anti-spatter and anti-oxidation performance, extending service life by 2-3 times in harsh environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between D28-M11 and D32-M14 ceramic rings?\u003c\/strong\u003e\u003cbr\u003e\nA: The main difference is the outer diameter and thread size. D28-M11 has a 28mm outer diameter and M11 thread, designed for most standard power laser cutting heads (1000W-6000W). D32-M14 has a 32mm outer diameter and M14 thread, designed for higher power laser cutting heads (6000W-20000W). They are not interchangeable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What does a ceramic ring do in a laser cutting head?\u003c\/strong\u003e\u003cbr\u003e\nA: The ceramic ring has three critical functions: 1) Electrical insulation between the nozzle and the laser head body; 2) Mechanical fixation of the nozzle assembly; 3) Transmission of electrical signals for the capacitive height follow system. A damaged ceramic ring will cause the height follow system to fail.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my ceramic ring?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions: Standard Type lasts 2-3 months, Reinforced Type lasts 3-4 months, Gold-Plated Type lasts 4-6 months. However, it should be replaced immediately if you notice any cracks, chips, or if the height follow system becomes unstable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will these ceramic rings work with my laser cutting machine?\u003c\/strong\u003e\u003cbr\u003e\nA: Our D28-M11 and D32-M14 ceramic rings are universally compatible with over 95% of mainstream fiber laser cutting heads, including Raytools, Precitec, WSX, Bodor and OSPRI.

Ceramic rings have a built-in copper electrode that transmits electrical signals for the capacitive height follow system. They are not interchangeable and serve different functions in the laser cutting head assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Which WSX cutting head uses which ceramic model?\u003c\/strong\u003e\u003cbr\u003e\nA: M8 spacer for NC30, NC30A; M11 spacer for NC60; 3D-M8-17.8 for ND30 3D head; D24-M8-H12 for NC30C; D28-M20-H25 for NC60B, NC60C; D41-M11-34.5 for NC120, NC150 high-power heads. If you are unsure, please contact our sales team with your cutting head model number.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is special about the 3D-M8-17.8 model?\u003c\/strong\u003e\u003cbr\u003e\nA: The 3D-M8-17.8 is specifically designed for WSX 3D robotic cutting heads. It features a compact structure and optimized height to avoid interference with workpieces during complex 3D cutting paths and bevel cutting operations. Standard 2D ceramic rings will not work properly in 3D cutting heads.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will these WSX ceramic parts work with non-WSX cutting heads?\u003c\/strong\u003e\u003cbr\u003e\nA: No, these ceramic rings and spacers are specifically designed for WSX cutting heads only. They have unique dimensions and interface specifications that differ from other brands. Using them on non-WSX equipment will result in poor fit, air leakage and unstable cutting performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my WSX ceramic ring?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions, a WSX ceramic ring should last 2-3 months. However, it should be replaced immediately if you notice any cracks, chips, or if the height follow system becomes unstable. Frequent collisions between the nozzle and workpiece will significantly shorten its service life.\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 30px; padding: 15px; background-color: #e3f2fd; border-radius: 4px;\"\u003e\n  View our full range of \u003ca href=\"https:\/\/www.linkmetalcnc.com\/collections\/laser-cutting-accessories\" style=\"color: #1976d2 !important; text-decoration: none; font-weight: 500 !important;\"\u003elaser cutting accessories\u003c\/a\u003e including WSX nozzles and protective lenses.\n\u003c\/p\u003e","brand":"Link Metal CNC","offers":[{"title":"M8 Ceramic Spacer(D15.6)","offer_id":47962918584542,"sku":"LMCNC-CERAMIC-WSX-M8-SPACER","price":4.99,"currency_code":"USD","in_stock":true},{"title":"M11 Ceramic Spacer(D19.5)","offer_id":47962918617310,"sku":"LMCNC-CERALMCNC-CERAMIC-WSX-M11-SPACERMIC-WSX-M8-SPACER","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3D-M8-17.8(WTC-05)","offer_id":47962918650078,"sku":"LMCNC-CERAMIC-WSX-3DM8-17.8","price":4.49,"currency_code":"USD","in_stock":true},{"title":"D24-M8-H12","offer_id":47962918682846,"sku":"LMCNC-CERAMIC-WSX-D24M8H12","price":5.67,"currency_code":"USD","in_stock":true},{"title":"D28-M20-H25 (ND18)","offer_id":47962918715614,"sku":"LMCNC-CERAMIC-WSX-D28M20H25","price":5.67,"currency_code":"USD","in_stock":true},{"title":"D41-M11-34.5(（万顺兴NC150）【WTC-11】)","offer_id":47962918748382,"sku":"LMCNC-CERAMIC-WSX-D41M11-34.5","price":23.63,"currency_code":"USD","in_stock":true},{"title":"D28-M11-H11.8(Genuine)","offer_id":48005966069982,"sku":null,"price":18.9,"currency_code":"USD","in_stock":true},{"title":"Other models please contact us","offer_id":48006022889694,"sku":null,"price":4.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/8858\/5950\/files\/link-metal-cnc-ceramic-ring-wsx-11.jpg?v=1773049377"},{"product_id":"bodor-ceramic-ring-fiber-laser-cutting-head","title":"Link Metal CNC Bodor Ceramic Ring for Fiber Laser Cutting Heads","description":"\u003ch2\u003eBodor Ceramic Ring for Fiber Laser Cutting Heads\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eProfessional industrial-grade Bodor dedicated ceramic rings, essential core insulation consumables for all Bodor series fiber laser cutting heads.\u003c\/strong\u003e Designed to insulate the laser cutting head nozzle body, fix the optical assembly, and ensure stable electrical signal transmission for the capacitive sensor, our Bodor ceramic rings guarantee the normal operation of the laser cutting head height follow system.\u003c\/p\u003e\n\n\u003cp\u003eWe offer two professional models: High Power D31-M1 for high-power plane cutting and 3D-M8 for 3D robotic cutting.

Dual hole ceramic rings feature an optimized double airflow structure that delivers more uniform protective gas output around the nozzle. This improves cutting stability, reduces slag adhesion, and delivers better cutting quality especially for high-speed cutting and thick plate cutting applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Which OSPRI cutting heads use these ceramic rings?\u003c\/strong\u003e\u003cbr\u003e\nA: M8-D17.8 for LC100\/LC200; M8-D21.4-H13 for LC300; 3D-M8-D21.4 for 3D-A\/3D-B; 3D-M8-D21.5 for 3D-C\/3D-D; M10-D25-H19 for LC600; M11-D41-H22 for LC1200; M11-D41-H26.5 for LC2000\/LC3000. If unsure, contact us with your cutting head model.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between 3D-M8-D21.4 and 3D-M8-D21.5?\u003c\/strong\u003e\u003cbr\u003e\nA: The main difference is the outer diameter. 3D-M8-D21.4 is designed for older OSPRI 3D-A and 3D-B robotic cutting heads, while 3D-M8-D21.5 is for newer 3D-C and 3D-D cutting heads. They are not interchangeable due to different dimensions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use universal ceramic rings on my OSPRI laser machine?\u003c\/strong\u003e\u003cbr\u003e\nA: No, OSPRI cutting heads use unique interface specifications and dimensions that differ from standard universal ceramic rings. Using universal ceramic rings on OSPRI equipment will result in poor fit, air leakage, unstable height follow performance and potential damage to your cutting head.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my OSPRI ceramic ring?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions, an OSPRI ceramic ring should last 2-3 months. However, it should be replaced immediately if you notice any cracks, chips, or if the height follow system becomes unstable. Frequent collisions between the nozzle and workpiece will significantly shorten its service life.\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 30px; padding: 15px; background-color: #e3f2fd; border-radius: 4px;\"\u003e\n  View our full range of \u003ca href=\"https:\/\/www.linkmetalcnc.com\/collections\/laser-cutting-accessories\" style=\"color: #1976d2 !important; text-decoration: none; font-weight: 500 !important;\"\u003elaser cutting accessories\u003c\/a\u003e including OSPRI nozzles and protective lenses.\n\u003c\/p\u003e","brand":"Link Metal CNC","offers":[{"title":"M8-D17.8 Single Hole","offer_id":47965381722334,"sku":"LMCNC-CERAMIC-OSPRI-M8D17.8-SINGLEHOLE","price":3.39,"currency_code":"USD","in_stock":true},{"title":"M8-D17.8 Dual Hole（FC-11）","offer_id":47965381689566,"sku":"LMCNC-CERAMIC-OSPRI-M8D17.8-DUALHOLE","price":3.9,"currency_code":"USD","in_stock":true},{"title":"3D-M8-D21.4 (Dual Hole)（FC-40）","offer_id":47965381656798,"sku":"LMCNC-CERAMIC-OSPRI-3DM8-D21.4","price":4.25,"currency_code":"USD","in_stock":true},{"title":"M8-D21.4-H13(Three Holes)（FC-15）","offer_id":47965381886174,"sku":"LMCNC-CERAMIC-OSPRI-M8D21.4-H13","price":5.2,"currency_code":"USD","in_stock":true},{"title":"3D-M8-D21.5（FC-218）","offer_id":47965381755102,"sku":"LMCNC-CERAMIC-OSPRI-3DM8-D21.5","price":4.25,"currency_code":"USD","in_stock":true},{"title":"M10-D25-H19（FC-04）","offer_id":47965381787870,"sku":"LMCNC-CERAMIC-OSPRI-M10D25-H19","price":7.09,"currency_code":"USD","in_stock":true},{"title":"M11-D41-H22（FC-14）","offer_id":47965381820638,"sku":"LMCNC-CERAMIC-OSPRI-M11D41-H22","price":28.36,"currency_code":"USD","in_stock":true},{"title":"M11-D41-H26.5( FC17）","offer_id":47965381853406,"sku":"LMCNC-CERAMIC-OSPRI-M11D41-H26.5","price":43.71,"currency_code":"USD","in_stock":true},{"title":"Other models available upon request.","offer_id":48010260873438,"sku":null,"price":3.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/8858\/5950\/files\/link-metal-cnc-ospri-ceramic-ring-01.jpg?v=1773117886"},{"product_id":"precitec-ceramic-ring-fiber-laser-cutting-head","title":"Link Metal CNC Precitec Ceramic Ring for Fiber Laser Cutting Heads","description":"\u003ch2\u003ePrecitec Ceramic Ring for Fiber Laser Cutting Heads\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eProfessional industrial-grade Precitec dedicated ceramic rings, essential core insulation consumables for all Precitec series fiber laser cutting heads.\u003c\/strong\u003e Designed to insulate the laser cutting head nozzle body, fix the optical assembly, and ensure stable electrical signal transmission for the capacitive sensor, our Precitec ceramic rings guarantee the normal operation of the laser cutting head height follow system.\u003c\/p\u003e\n\n\u003cp\u003eThis complete product series covers the full range of Precitec dedicated models, including mini precision type, 3D robotic cutting type, conventional standard type and KTX series dedicated models.

A worn or damaged locking ring will cause unstable cutting performance, poor cut quality and increased risk of collisions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are locking rings interchangeable between different brands?\u003c\/strong\u003e\u003cbr\u003e\nA: No, locking rings are brand and model specific due to different thread sizes and dimensions. Using the wrong locking ring will result in poor fit, loose components and potential damage to your cutting head. Always select the correct model for your specific cutting head.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my locking ring?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions, a locking ring should last 6-12 months. However, it should be replaced immediately if you notice any stripped threads, deformation, or if the nozzle cannot be tightened properly. Frequent nozzle changes and collisions will accelerate wear.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between stainless steel and aluminum alloy locking rings?\u003c\/strong\u003e\u003cbr\u003e\nA: Stainless steel locking rings offer higher durability and better corrosion resistance, making them ideal for high-power cutting and harsh environments. Aluminum alloy locking rings are lighter and provide better thermal conductivity, suitable for standard power cutting applications. We match the material to original factory specifications for each model.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do you offer locking rings for other brands besides Raytools, WSX and Precitec?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, we can provide custom locking rings for most other laser cutting head brands upon request.
