6900 Series ball bearing

Product detail :

The 6900 Series, extralight ball bearingsare normally used in applications where space limitations are a primary consideration and shaft sizes are relatively large. This series is available in sealed and shielded configurations. Smaller but more ball complements still enable the bearing to withstand appropriate loading capability.

Ball bearingis composed of an outer ring, inner ring, a set of ball and a cage. Structure is simple and easy maintenance. Mainly used to bear radial load, but also bear certain axial load, when the axial clearance increased, will have the performance of angular contact ball bearings and can bear large axial load, this kind of bearing low friction coefficient, high limiting speed, size range and diverse.

They are widely used in Motors, car engines, power tools, robots, air-conditioner motors, vacuum cleaner motors, oil fume motors, office equipments, fitness equipments, textile machinery and so on.
