// CC Type:

21300.., 22200.., 22300.., 23000.., 23100.., 23200.., 23900.., 24000.., 24100..
EA, C, CD, CA,MB, E,K30, which are designed for high load capacity, are available.

Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages.

Type EA has especially high load capacity, features low torque, and has a high-strength cage.

An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.
To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.

The spherical roller bearing is a bearing in which a drum roller is assembled between an inner ring having two raceways and an outer ring having a spherical raceway.

Spherical roller bearings are divided into: cylindrical bore, conical bore.

The conical bore has a taper of 1:12 followed by a self-aligning roller bearing of type K (type 153000 or 113000) and a 1:30 post-alignment roller bearing with the code K30. When this type of bearing is fitted with a conical shaft, the inner ring moves axially to adjust the radial clearance of the bearing.

Spherical roller bearing post code:

The taper hole self-aligning roller bearings with K and K30 code numbers are installed on the matching adapter sleeves to become K+H and K30+H bearings. This type of bearing can be mounted on an optical axis without shoulders. It is suitable for applications that require frequent installation and removal of bearings. In order to improve the lubrication performance of the bearing, an annular oil groove is formed in the outer ring of the bearing and an evenly distributed three oil holes are drilled, followed by the code W33.
