Cylindrical Roller Bearing

Bearing Features

1. High radial load capacity and low friction coefficient2. The rollers and raceways are in line contact or modified line contact, suitable for withstanding heavy loads and impact loads3. Low friction coefficient, suitable for high-speed operation, with a limiting speed close to that of deep groove ball bearings4. N and NU types are axially movable and can be used as free-end supports5. High requirements for the machining of shafts and housing bores; the deflection of the outer ring axis must be strictly controlled after installation to avoid contact stress concentration6. The inner ring or outer ring is separable, facilitating installation and disassembly

Bearing Classification

Classified by the number of rolling element rows:• Single row: N, NU, NJ, NF, NUP, NFP, NH (NJ HJ) types• Double row: NN, NNU, NNF types• Four row: FC, FCD types

Application Scope

Large and medium-sized electric motors, railway rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, hoisting and conveying machinery, etc.
