Findbearing.com supplies high quality KR, KRE curve roller bearing.
Note:
– For the KP series curve roller, the rolling needles are guided by the retainer, while the outer ring is axially guided by the retaining ring on the stud. This kind of roller is suitable for heavy load and middle rotating speed. Lubricating period is prolonged due to the big grease storage design space. The working temperature is -30 centigrade to 100 centigrade.
– Model KRE is the type with eccentric sleeve. It can be supplied with eccentric collar. The rollers can be adjusted from the stud end. Lubricating grease can be charged from both sides of the stud.
– When the bearing outer ring(with outer cylindrical surface) is fitted with general bearings in the seat holes, basic stable load C and Co should be used while used as rolling wheel, rated load Cw and COW should be used.
– The rotating speed will increase by about 30% if oil lubricant is used.
