Product Description of cylindrical roller bearing
Cylindrical roller bearings have high bearing capacity. The new structure design of the flange and the end face of the roller not only improves the axial bearing capacity, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the service performance of the bearing. It can withstand large radial loads and is suitable for high-speed operation, such as large and medium-sized motors, locomotive and rolling stock, machine tool spindles, internal combustion engines, generators, reducers, rolling mills, and lifting and conveying machinery.
Bearing characteristics
1. The roller and the raceway are in contact with the wire or
repaired, and have a large radial load capacity, which is suitable
for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and
the limit speed is close to the deep groove ball bearing.
3. N-type and NU-type can move axially, can adapt to the change of
the relative position of the shaft and the shell caused by thermal
expansion or installation error, and can be used as free end
support.
4. The machining requirements of the shaft or the seat hole are
high. After the bearing is installed, the relative deflection of
the outer ring axis should be strictly controlled to avoid contact
stress concentration.
5. The inner or outer ring can be separated for easy installation
and removal.
