Deep Groove Ball Bearing
608 hybrid ceramic ball bearing is a deep groove ball bearing featuring a combination of ceramic balls and metal inner/outer rings.
Model Number: 608
Size: 8x22x7mm
Material: hybrid ceramic ZrO with stainless steel
Weight: 0.012KG
Lead Time: 3-5 days
Specification
Hybrid ceramic ball bearings are a type of composite bearing that combines metallic materials (such as bearing steel or stainless steel) with non-metallic materials (such as silicon nitride, zirconia, etc. as ceramics). Their core feature is that ceramic balls are used as the rolling elements, combined with metal inner and outer rings, and the performance is complementary through the combination of different materials.

Main features:
1. Material combination: The common configuration consists of metal inner and outer rings (steel or stainless steel) + ceramic balls (such as silicon nitride, zirconia, etc.). Among them, silicon nitride is chosen as the preferred material due to its superior comprehensive performance.
2. Performance advantages:（1) High temperature resistance (up to 300°C or above), strong corrosion resistance;
（2) Density is 60% lower than that of steel, with low inertia, suitable for high-speed operation (rotation speed can be more than 1.5 times that of ordinary bearings);
（3) Self-lubricating property, can extend service life without lubrication or with poor lubrication conditions (up to 2-3 times that of ordinary bearings);
（4) Excellent electrical insulation performance, suitable for conductive environments.
