Cylindrical Roller Ball Bearing
Bearing radial size is small, it have four row cylindrical rollers. Comparing to the same size ball bearings, the bearings have greater radial load carrying capacity. The limit speed of them is similar with deep groove ball bearing. But it only endure radial force, can not bear axial force. Because there is no inner wall, inner and outer components can be installed separately. They are widely used in metallurgical industry, mainly used in hot and cold rolling mill.
