What is different during CA and CC type of Spherical roller bearings?

What is different during CA and CC type of Spherical roller bearings? How many the information of CA and CC do you learn? If you are intersted, take some time to have a look this catical.

Spherical roller bearings is a very common type of roller bearings, there are two most common structure - CA type and CC type, today we take a look at the difference between them.

Spherical roller bearings CA type and CC type two major structures mainly to the bearing inner ring with or without edge, keep frame is a car entity or stamping frame to distinguish between the two can not be common.

First, the structure is different

CA type: the whole brass processing keep frame, inner circle without middle flange, end face has two small flange, roller is symmetrical.

CC type: the roller is symmetrical, the inner ring has no suspension point, no end stop. The cage is divided into two parts. This material is a pressed steel frame cage. A movable centre ring is designed between the rollers and the rollers, which can effectively reduce the internal friction of the bearings, effectively assist the rollers in the non-stressed area to enter the load carrying area correctly, and improve the limiting speed of the bearings.\

Second, the internal space is different

CA type spherical roller bearings with low noise, has a certain self-lubricating function. Roller occupies small space, limit the external dimensions and number of roller body, so that its bearing capacity is limited, keep frame has its own activities guide ring. Compared with the same specifications of the CA type, CC type has a larger internal space, you can increase the number of rollers to increase the load.

Third, different axial load carrying capacity

In terms of application occasions, due to the CA structure of the cage in the limited bearing dimensions under the condition of occupying a larger internal space, to a certain extent, to limit the rolling body dimensions and number, thus reducing the bearing to further improve the radial load carrying capacity of the ability. In heavy load, high speed conditions, should be more CC structure. Such as: some use environment is high temperature environment must use CC type spherical roller bearings.
