Description
The roller and raceway are in line contact or off-line contact, which has large radial bearing capacity and is suitable for bearing heavy load and impact load..Low friction coefficient, suitable for high speed, and the limit speed is close to deep groove ball bearing..N-type and NU-type can move 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 machining requirements for shaft or seat hole are higher, and the relative deviation of outer ring axis after bearing installation should be strictly controlled to avoid contact stress concentration..The inner ring or the outer ring can be separated, which is convenient for installation and disassembly..The raceway and roller of cylindrical roller bearing are in geometric shape. After the improved design, it has a high bearing capacity. The new structural design of the flange and the roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the flange, and improves the service performance of the bearing.
