NUP2305
Basic Design:
It is the combination of 2 machined and polished grooved raceways(inner &outer rings),guilding a number of appropriate cylindrical rollers as the rolling elements,with a cage or full complement.This type bearings are designed to carry heavy radial loads at high speed.
Detailed Description:
Cylindrical roller bearing owns large load capacity,and mainly bears radial load.There is small friction between its roller and the rim of its loop,which is suitable for high-speed rotation.
The roller and the the raceway of cylindrical roller bearing are defined as line contacts,which have large radial load capacity and are suitable to withstand heavy load and shock load.With small coefficient of friction,cylindrical roller bearing is suitable for high-speed rotation,whose limiting speed is closed to that of deep groove ball bearing.
Application:
Cylindrical Roller Bearing are used for medium and large motors,locomotives,machine tool spindle,internal combustion engines,generators,vibrating screen,gas turbine,reduction gearbox,rolling mill,vibating screen and elevating machinery.
