HS Alloy Angular Contact Joint Bearing Inner Ring Tolerance

2019-08-14

HS alloy angular contact spherical plain bearings are suitable for axial loads in radial loads and directions, or combined loads in radial and axial directions. The load capacity is determined by the contact angle of the bearing (the nominal contact angle of the bearing is greater than 00, less than or equal to 450). According to the large antenna, the axial load capacity is strong, but the ability to withstand the combined load is low. When the radial load is applied, additional axial force will be caused, so it is generally installed in pairs.

1, HS alloy angular contact joint bearing can replace the relevant bearing products

(1) HS alloy angular contact joint bearing can replace the 32000 type (20 series) tapered roller bearing in GB/T297-94 and corresponds to the 2007100E model size in the original GB297-64. If the user needs other series, you can choose the size and installation size according to your needs, such as 30200 type (7200E type); 32200 type (7500E type); 30300 type (7300E type); 32300 type (7600E type); 31300 type ( Model 27300E).

(2) HS alloy angular contact joint bearing can replace GB9164-90 angular contact joint bearing.

(3) The shape and installation dimensions of HS alloy angular contact joint bearings correspond to GB9164-90 angular contact joint bearings.

2. HS alloy angular contact joint bearing and shaft and bearing seat

The bearing and the shaft are matched by the base hole, and the bearing and the bearing seat are matched by the base shaft.

Bearing and shaft fit tolerance band code:

General load: m6 j5 j6 h6

Heavy load, variable load: h7 m6

Recommended bearing tolerances for bearings and housings:

Light load: H6 H7

Heavy load, variable load: M7

In order to ensure the interchangeability of the HS alloy angular contact joint bearing and the corresponding rolling bearing, the bearing inner ring tolerance is manufactured according to GB/T307.1-94 Class 0 tolerance standard.
