What is the difference between B type sphericals and C type?
The “B” type spherical has asymmetric rollers guided by three fixed inner ring ribs that provide better skewing control. The retainer in this bearing is finger type and provides optimum lubrication access. The “C” type spherical employs symmetric rollers and utilizes a floating center guide ring. As no fixed guide rings are used in this design, a window type cage is necessary to guide the rollers.
