RN Series Cylindrical Roller Bearing for Dynamo Motor
Product Introduction:
Cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial
load. The rolling element has little friction with the ferrule rib and is suitable for high speed
rotation. According to the ferrule with or without ribs, it can be divided into single row
cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller
bearings such as NNU and NN. The bearing is a structure in which the inner ring and
the outer ring are separable.
SL Type Cylindrical Roller Bearings can be relubricated via the inner or outer ring.
For this purpose, both bearing rings have an integral circumferential lubrication groove and axial lubrication holes.
It is recommended that catalogue bearings lubricated with a grease in accordance with GA08 should be relubricated using the grease Arcanol LOAD150.
Cylindrical roller bearing main application:
Large and medium-sized motor, engine vehicle, machine tool spindle, internal combustion engine, generator, gas turbine, reducer, rolling mill, vibrating screen and lifting the transport machinery, etc.
