Several factors bearing type selection
Oct 25, 2016

1, bearing radial load

Main radial load bearing for radial bearings. The bearings the nominal contact angle A0<=45 0. Rain the same roller bearings more than ball bearings can accommodate radial loads.

NU and n type cylindrical roller bearings can only accommodate radial loads, other types of radial bearings can accommodate radial loads, can carry axial load.

2, axial load of bearing

Main axial load of bearing for thrust bearing, nominal contact A0>450 in the corner of it. Thrust angular contact ball bearings and thrust bearings according to the different structure can bear one or axial load in both directions. When the bear special optimization of high thrust force cylindrical roller bearing and thrust roller bearings.

Thrust spherical roller bearings and single direction angular contact thrust ball bearings can also accommodate axial loads and radial load, the other thrust bearings can only accommodate axial loads.

3, bearing its own length compensation

Supporting a shaft and bearings are fixed bearings and bearing combination swimming structure. Free bearing compensating shaft length error and thermal expansion.

NU-type and n-type cylindrical roller bearing is the ideal free bearing, the bearing itself can compensate for the length. The bearing inner and outer rings can be a tight fit.
