2	Description	Cylindrical roller bearings belong to separable bearings, with easy method of mounting and dismounting. They can be classified into single row, double rows and four rows. As per different rib of the ring, single-row cylindrical roller bearings can be divided into N series, NU series, NF series, NUP series and so on. Cylindrical roller bearings carry a very heavy radial loads.

Features of Cylindrial Roller Bearing:

1. The roller and raceway for the line contact or offline contact, radial bearing capacity big, apply to under heavy load and impact load.

2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.

3. The N type and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.

4. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration.

5. The inner ring or outer ring separable, easy to install and disassemble.
