Structural types of spherical roller bearings

Spherical roller bearings are divided into: cylindrical bore, conical bore. The taper of the tapered inner hole is 1:12 for the rear-mounted spherical roller bearing (type 153000 or 113000) with the rear code K30 and the 1:30 rear-mounted spherical roller bearing with the code name K30. When this type of bearing is matched with a conical shaft, the radial clearance of the bearing can be adjusted by moving the inner ring in the axial direction.
