Findbearing.com supplies high quality KRV, KRVE curve roller bearing.
Note:
– KRV series curve rollers have the same structure as KR type, but they are full complement needle bearings. They can bear heavier load but lower rotating speed. They should be lubricated frequently.
– Model KRVE 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.
