Details

1.self-algning roller bearings with two rows rollers, are mainly used to bear radial load,but also can take axial load in either direction. this kind of bearing have a high radial load capacity, especially suitable for working heavy loads or vibration, but unable to withsand pure axial load. good aligning performance, can compensate the coaxiality error.
2.mainly purposes: papermaking machinery, speed reducer, railway vehicle axle, roller mill, crusher, vibrating screen, printing machinery,woodworking machinery,self-aligning bearing with vertical unit etc.
3.self-aligning roller bearings can be divided into, cylindrical hole, tapered hole.
4.for the self-aligning bearings, a large number of bearings generally use mechanical or hydraulic pressure method for installation.
