1.The Introduction of Cylindrical Roller Bearing :
Rolling element is a cylindrical roller to the heart of rolling bearings. Cylindrical roller bearing internal structure of the roller was 90 ° perpendicular to each other cross-arranged (which is the origin of the name of cross-roller bearings), the gap between the roller with cage or isolator block can prevent the roller tilt or roller Between the grinding, effectively preventing the increase of the rotation torque.
2.The Features of Cylindrical Roller Bearing :
1. Roller and raceway for line contact or repair offline contact,
radial bearing capacity, suitable for heavy load and impact load.
2. Friction coefficient is small, suitable for high-speed, speed
close to the deep groove ball bearings.
3.N-type and NU-type axial movement, can adapt to thermal expansion
or installation error caused by the relative position of the shaft
and shell changes, can be used for free-end support.
4. Shaft or seat hole processing requirements are higher, the
relative deviation of the outer ring axis after installation to
strict control, so as not to cause contact stress concentration.
5. Inner or outer ring can be separated, easy to install and
remove.
