MAXIMUM CAPACITY BALL BEARINGS

There are two basic types of radial ball bearings: the non-filling slot or maximum capacity type ball bearings with a filing slot.

Maximum capacity ball bearings have a deep, uninterrupted raceway in inner and outer rings. This design carries heavy radial and moderate bidirectional thrust loads. The maximum capacity ball bearing contains more balls than an equivalent-sized Conrad type, and therefore, a higher radial load capacity. However, because of the filling slots, thrust loads must be light and applied only in combination with a heavier radial load. Exceeding rated thrust causes balls to roll over the filling slots, causing severe damage to the ball bearing. Ball Bearings feature a load capacity, which can also be increased by using double row ball bearings instead of the max type.
