Black zirconia ceramic slotted indexing disks are made from high-toughness zirconia ceramic with a dense structure and stable black appearance. The material is suitable for disk-shaped ceramic parts that require wear resistance, dimensional stability, and a clean polished surface. Compared with coated surfaces, black zirconia ceramic can better maintain its appearance during polishing, assembly, and long-term use.
The slotted indexing disk structure is designed for positioning, indexing, alignment, rotation control, and precision assembly applications. It offers good hardness, toughness, scratch resistance, corrosion resistance, electrical insulation, and non-magnetic performance. Accurate slot geometry and clean edge quality help improve fit, movement control, and long-term wear performance in precision devices.
Black zirconia ceramic slotted indexing disks are used in watch components, precision positioning mechanisms, indexing structures, automation equipment, optical devices, electronic insulating parts, decorative hardware, and wear-resistant mechanical assemblies. For projects requiring special slots, holes, polished surfaces, tight dimensions, or customized disk profiles, related support is available through precision ceramic components manufacturing.
Delivery time depends on the disk diameter, thickness, slot design, tolerance requirements, edge treatment, polishing level, appearance standard, inspection requirements, and order quantity. Products with complex slot geometry, mirror polishing, or strict cosmetic requirements may require additional machining and inspection time.
Final lead time will be confirmed after drawing review, material confirmation, machining feasibility evaluation, surface finish requirements, and production schedule confirmation.
Black zirconia ceramic slotted indexing disks are precision ceramic parts used for positioning, indexing, alignment, rotation control, and decorative mechanical assemblies. Made from high-toughness black zirconia ceramic, they offer a smooth black surface, good wear resistance, electrical insulation, and stable dimensions. They are suitable for compact precision devices where metal parts may wear, corrode, or affect appearance over time.
This product is made from high-toughness black zirconia ceramic, a dense technical ceramic material with good strength, wear resistance, corrosion resistance, electrical insulation, and a refined black surface. It is suitable for small disk-shaped parts that need both mechanical function and a clean appearance.
Compared with many other ceramic materials, black zirconia ceramic has better toughness, which helps reduce the risk of cracking or edge chipping during machining and use. It is suitable for slotted structures, thin edges, polished surfaces, and parts that require repeated contact or visible assembly.
Black zirconia ceramic slotted indexing disks are often used in precision assemblies where slot position, edge quality, surface finish, and appearance all matter. The slotted structure can support positioning, indexing, alignment, or controlled movement in compact mechanical systems.
