Product Features
1. Mainly for applications where the bearing inner ring rotates.
2. Double Shielded to to keep lubricant in and contaminants out.
3. It accommodates redial load while can take axial load to some extent.
4. With rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads.
5. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan.
6. These 628Z bearings can be used for: Cooling tower, plastic welding machine, cutting machine, rolling guide, bucket elevator, kneader, Heidelberg printing machine, material testing machine, hardware, multi-function packaging machine, food sterilization equipment, packing, solid waste treatment equipment, vertical pump , Electric welding machine, spinning equipment (textile machine), hexagonal lathe, electronic component forming machine, etc.
