Model KR, KR…PP Curve Roller
In Model KR, KR…PP curve roller, the rolling body is guided by cage and the outer is axially guided by the
baffle ring on the bolt. It is suitable for heavy load and middle rotational speed. Since the bearing has a
large grease-storage space, it has a long-term lubrication cycle. Model KR…PP curve roller has the
contact-type seal structure.

the high-efficient gas seal.
This kind of cure roller bearing can withstand the heavy load and the shock axial load because it is guided
axially by roller.
