SKF Cylindrical roller bearing

The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has retaining edge or not, 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 of inner ring and outer ring

for cylindrical roller bearings with no flange on the inner or outer ring, the inner ring and outer ring can move relatively axially, so they can be used as free end bearings. A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel plate stamping cage or copper alloy turning solid cage are used. However, some use polyamide formed cages

features
1 The roller and raceway are in line contact or repair line contact, with large radial bearing capacity, which is suitable for bearing heavy load and impact load< br>2. Low friction coefficient, suitable for high speed, the limit speed is close to the deep groove ball bearing< br>3. 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< br>4. The processing requirements for the shaft or seat hole are high. After the bearing is installed, the relative deflection of the outer ring axis shall be strictly controlled to avoid contact stress concentration< br>5. The inner ring or outer ring can be separated for easy installation and disassembly
