The difference between CC and CA spherical roller bearings

Spherical roller bearings are a very common type of roller bearings. There are two most common structures - CA type and CC type. The two structures are mainly distinguished by whether the inner ring of the bearing has a flange, and whether the cage is a machined solid or a stamped frame. The two cannot be used interchangeably.

CA type: integral brass machined cage, no intermediate flange on the inner ring, two small flanges on the end face, and symmetrical rollers.

CC type: symmetrical rollers, no stop points on the inner ring, and no end stops. The cage is divided into two parts.

CA type spherical roller bearings use low noise, have a certain self-lubricating function, but the load capacity is limited, and the cage has its own movable guide ring. The CC type has a larger internal space, and the load can be increased by increasing the number of rollers.
