This ceramic motor shaft sleeve assembly is designed for precision rotating systems and high-speed electric motors. The structure combines a 99% alumina ceramic sleeve with silicon carbide end bushings, providing excellent wear resistance, dimensional stability, and electrical insulation. The alumina ceramic core ensures smooth rotation and high dielectric strength, while the silicon carbide end components offer superior hardness and abrasion resistance. This hybrid ceramic structure effectively protects the shaft and surrounding components, extending the service life of the motor assembly.

Yes. We offer CNC machining, ceramic injection molding, cold isostatic pressing, hot pressing, dry pressing and casting to produce non-standard parts based on your drawings or samples.
Different products have different MOQ, if you have mass production in future, we can discuss MOQ again to meet your requirement.
Our products meet ISO 9001:2015 and IATF16949 standards. Material COA (Certificate of Analysis) and mechanical test reports (e.g., hardness, density, flexural strength) are available.
Standard tolerance is ISO2768-M. Precision machining can reach ±0.001mm (depending on material and design).
Standard parts: 1-7 days; Custom parts: 30-60 days (complex designs require additional evaluation).
We use two or three layer protection: shock-absorbing foam + reinforced cartons or shock-absorbing foam + individual blister boxes + reinforced cartons. Fragile labels are applied for delicate parts.
Yes. Provide your application conditions (temperature/medium/pressure/load), and our engineers will recommend the optimal material solution.
Report the issue within 7 days with photos/videos. Verified defects will be replaced or refunded at no cost.
Yes. Contact our email info@innovasupplies.com to get more details about offline orders. For corporate transfers, provide full company name and tax ID for VAT invoice issuance.
Yes, for large orders, we can discuss by offline through email.
Returns are accepted if:
– Received incorrect product model/specification
– Manufacturing defects (non-human damage)
– Unopened packaging & resalable condition (standard parts only)
Claims must be filed within 7 business days after delivery.
Custom orders are non-returnable (unless with critical defects) as they are produced specifically for you. Pre-shipment inspection reports will be provided for approval.
Tours by appointment only. Submit 3 days in advance: company name, visitor position, purpose. Note: Clean-rooms require protective gear.
If you have mass production in future, 1-5 free standard samples are available and you pay the freight cost, custom samples charged at cost.
