 C     Features a stamped steel cage and stengthened symmetric roller.As a second generation design,these bearing designs are optimized to offer considerably higher load ratings than conventional designs for a broad range of application and long service life.

 CA  The alternative design of the second generation,these bearings feature a precision-machined brass cage and strengthened symmetric roller and are equivalent to C design in load rating.They are used to exchange with C design,particularly for large sizes.

E type is SKF Explorer Design, except E type cage, we also can supply EAE4 cage of Japanese standard.

Instruction of Spherical Roller Bearings:

Spherical roller bearing is made up of inside ring of double rollaway nest, outside ring of spherical rollaway, double row spherical balls containers and center rib. It also has the function of self-align, because of the coincide between the center of circular arcs in the outside rollaway nest and the center of bearing. What's more, it also can repair the error while in installing bearing into house, or the obliquity of outside ring and inside ring caused by the bending of axletree. This kind of bearings can endure much more radial load and a certain amount of axial load.

Dawson can offer you various kind of double row spherical roller bearings, which can be used in different situations, such as 20000CC, 20000E, 20000EAE4, 20000CA, 20000MB and so on.
