Self-Aligning Roller Bearing
Structure type:
spherical roller bearings are divided into: cylindrical inner hole, conical inner hole. The taper of the tapered inner hole is respectively 1:12 for the spherical roller bearing code-named K and 1:30 for the spherical roller bearing code-named K30. When this type of bearing is matched with a conical shaft, the radial clearance of the bearing can be adjusted by the axial movement of the inner ring.
Main applications:
papermaking machinery, deceleration devices, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings with seats.
