Material

Carbon Steel.
Recommended Fit: Shaft h6 (h8). Housing Bore H7 (H9).

Other Info.

The caged cylindrical rollers AZK and the complete bearings AZ in which AZK are combined with an inner ring (WS) and an outer ring (GS) are available.
The cage has a special precise structure which is highly rigid, and cylindrical rollers are outwardly arranged and guided by the cage with exact precision to enable them to withstand heavy loads even at high rotational speeds.
Owing to the high accuracy of the bearing height T, they are suitable for use in machine tools, ultra-high pressure pumps, etc.
These bearings are generally used by utilising their inner surface as the guide surface.
Larger sizes to suit 75 - 280mm shafts also available, P.O.A.

Mounting:
When mounting Thrust Bearings, the following items should be considered.
1. When inner and outer rings are not used, the hardness of the raceway surfaces should be 58~64HRC, the effective hardening depth should be adequate, and the surface roughness should be less than 0.2μmRa.
2. When mounting inner and outer rings to shaft and housing bore, dimensions related to mounting should be based on the dimension tables. Also, the mounting surfaces should be finished at right angles to the centre axis and they should be sufficiently rigid.
3. Thrust Roller Bearings are combinations of a copper alloy component and cylindrical rollers. When handling the AZK itself, care should be taken to prevent deformations, blemishes, etc.

Note: Allowable rotational speed figures apply to oil lubrication. For grease lubrication, a maximum of 25% of this value is allowable.
