One-way Thrust Ball Bearing · Two-way Thrust Ball Bearing

Structure, type and characteristics
NSK Thrust Ball Bearing has two types: one-way type and two-way type. It is designed to withstand thrust loads during high-speed operation. It is composed of a washer-like ferrule with a ball-rolling raceway groove. Since the ferrule is in the shape of a seat cushion, the thrust ball bearing is divided into two types: the flat seat cushion type and the self-aligning spherical seat cushion type according to the shape of the outer ring (chassis seat cut, fixed ring) seat. In addition, this bearing can withstand axial loads, but not radial loads.
NSK one-way thrust ball bearings consist of two washer-shaped rings with grooves (shaft washer and housing washer) and a ball-mounted cage. The ring installed on the shaft is called the shaft ring, and the ring installed in the bearing seat is called the seat ring.

Two-way thrust ball bearings consist of three rings and two cages with balls. If it is a two-way type, it takes the form of a shaft washer clamped by two cages equipped with balls.
Two-way thrust ball bearings use the middle ring installed on the shaft.   
1. Available in one-way and two-way types
2. In order to tolerate installation errors, whether it is one-way or two-way, spherical self-aligning spherical seat cushion type can be selected Or with spherical seat type.

One-way thrust ball bearing can bear one-way axial load, and two-way bearing can bear two-way axial load. Thrust ball bearings are also provided with self-aligning washers under the seat ring to compensate for shaft misalignment or mounting errors. Small bearings mainly use steel stamping cages; large bearings use car-made cages.

One-way thrust ball bearings usually use stamped cages and copper alloy machined cages.
The cage of the double-direction thrust ball bearing is the same as that of the one-direction thrust ball bearing of the same series.
The rated load listed in the dimension table is based on the cage area. In addition, the same type of bearing has different cages, and the number of balls also changes. In this case, the rated load is different from the value described in the dimension table.
