Cylindrical roller bearing

Cylindrical roller bearing characteristics:

1roller and raceway for the line contact or line contact, radial load capacity, is designed to withstand the heavy load and shock load.

2 friction coefficient is small, suitable for high speed, speed limit is close to deep groove ball bearing.

3type N and type NU axially movable, can adapt due to thermal expansion or installation error caused by the shaft and the housing relative position changes, can be used as a free end bearing using.

4axis or hole processing requirements of high bearing outer ring, after the installation axis relative deviation should be strictly controlled, so as to avoid the contact stress concentration.

The 5inner ring or outer ring can be separated, convenient installation and disassembly.

Main uses:

Large and medium-sized motor vehicles, locomotives, machine tool spindle, internal combustion engine, generator, gas turbine, gearbox, rolling mill, vibration sieve and lifting the transport machinery.
