NTN Thrust Ball Bearings

Single-direction Thrust Ball Bearings

These bearings have balls enclosed in a cage between the shaft raceway washer that corresponds to the inner ring and the housing raceway washer that fits the outer ring. They can bear only single-direction axial loads.

Cylindrical-Roller-Bearings

Double-direction Thrust Angular Contact Thrust Ball Bearings

These can support axial loads in both directions, with high rigidity in the axial direction due to a large contact angle. Their structure is not suited to grease-lubricated vertical shafts.

Needle-Roller-Bearing

High-speed duplex angular contact ball bearings (for axial loads)

These are used in back-to-back duplex (DF) arrangements and can support only bi-directional axial loads. They are superior to double-direction thrust angular ball bearings with low axial rigidity in high-speed properties.
