Curve Roller Bearings KR32
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.
Model KRV, KRV…PP Curve Roller
The structure of Model KRV, KRV…PP curve roller bearing is same with that of Model KR, KR…PP curve roller
bearing. Model KRV, KRV…PP curve roller bearing is the full complement needle roller bearing. This cure
roller bearing can with stand heavy load under the low speed. However it is necessary to add the
lubricating grease at regular intervals.
Model NUKR Cure Roller
Model NUKR cure roller bearing has the double-row roller structure. As same as parallel roller bearing, the
outer ring is guided axially by rolling body. The cover pressed in outer ring and the shoulder constitutes
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.
KRE KRE…PP Model KREV KREV…PP NUKRE Curve Roller
Model KRE, KRE…PP, KREV, KREV…PP and NUKRE curve roller bearings are the special-purposed bearings in
order to meet the supporting requirement of main machine. The outer ring has roller structure and the bolt
shaft substitutes the inner ring. It has compact structure and can be equipped with eccentric-strap. The
roller can be adjusted by means of the slot at end of bolt. The lubricating grease can be fed from both
ends of bolt.
