Characteristics of cylindrical roller bearing
Cylindrical roller bearing roller and raceway for line contact, radial bearing capacity, suitable for bearing heavy load and impact load.
The friction coefficient of cylindrical roller bearing is small, it is suitable for high speed, and the limit speed is close to the deep groove ball bearing.
Cylindrical roller bearings n-type and nu type can move axially, 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 ring or outer ring can be separated for easy installation and removal.
The machining requirements of the cylindrical roller bearing for the shaft and the seat hole are high. After the installation of the bearing, the relative deflection of the inner and outer ring axes should be strictly controlled to avoid the contact stress concentration.
The double row cylindrical roller bearing with 1:12 taper in the inner hole of the cylindrical roller bearing has adjustable radial clearance and high radial rigidity, which is suitable for the spindle of the machine tool.
