    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 with 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.

    Spherical roller bearing rear code:

    The tapered bore 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. For 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.
