Spherical roller bearing
Product Name: Spherical Roller Bearing
Product ID: 22200 22300 21300
Product Description: Spherical roller bearings have two rows of rollers, which are mainly subjected to a radial load and can also withstand axial loads in either direction.
details:
Spherical roller bearing types:

Spherical roller bearings are divided into: cylindrical inner bore and conical inner bore.

The taper of the conical inner bore is 1:12 rear spherical roller bearing (model 153000 or 113000) with code K and 1:30 rear spherical roller bearing code K30. When such a bearing is matched with a conical shaft, the inner ring moves axially to adjust the radial clearance of the bearing.

Introduction to spherical roller bearings:

Spherical roller bearings have two rows of rollers that are mainly subjected to a radial load and can also withstand axial loads in either direction. High radial load capacity, especially suitable for heavy or vibration loads, but not for pure axial loads. The outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good and it can compensate for the coaxiality error.

Spherical roller bearing rear code:

The tapered roller spherical roller bearings with the rear code K and K30 are mounted on the matching adapter sleeves, which become the rear bearing code K+H and K30+H bearings. This type of bearing can be mounted on an optical axis without a shoulder and is suitable for applications where the bearing needs to be installed and removed frequently. In order to improve the lubrication performance of the bearing, the outer ring of the bearing has an annular oil groove and is drilled with three oil holes evenly distributed, and the rear code is W33.
