Electric Generator Gylindrical Roller Bearing High Load Easy
Installation
1. Product Description
Electric Generator Gylindrical Roller Bearing High Load Easy
Installation according to whether the ring has retaining edge or
not has, it can be divided into single row cylindrical roller
bearings such as NU, NJ, NUP, N and NF, and double row cylindrical
roller bearings such as NNU and NN.The bearing is a separable
structure with inner ring and outer ringthe rolling body is the
centripetal rolling bearing of cylindrical roller.The internal
structure of cylindrical roller bearing adopts parallel arrangement
of rollers, and spacer retainer or isolation block is installed
between rollers, which can prevent the inclination of rollers or
mutual friction between rollers and effectively prevent the
increase of rotating torque.Cylindrical roller and raceway line
contact, radial load capacity is large.It is not only suitable for
heavy load and impact load, but also suitable for high speed
rotation.More specification pls contact us.

3. Application
Electric Generator Gylindrical Roller Bearing High Load Easy
Installation are widely applied in machine tool,gearbox,rolling
mill,electric generator,vibrating screen etc.
4. Advantages
This series cylindrical roller bearing with small friction coefficient, suitable for high speed, limit speed
close to deep groove ball bearings.N type and NU type can be moved axially, which can adapt to the
change of relative position between shaft and shell caused by
thermal expansion or installation error, and can be used as free
end support.The inner or outer ring can be separated for easy
installation and disassembly.Cylindrical roller bearing raceway and
rolling body are geometric shape.After the improved design, it has
a excellent high bearing capacity. The new structure design of the
retaining side and the retaining side face not only improves the
bearing's axial bearing capacity, but also improves the lubrication
condition of the contact area between the retaining side and the
retaining face, and improves the bearing's performance.
