Explanation: cylindrical roller and raceway for line contact bearing. Large load capacity, mainly bear radial negative

Acknowledge. Roller and ring guard friction small, suitable for high speed rotation. According to the ring have without block

May, NU, NJ, NUP, N, NF, such as single bearing, and NNU, NN, etc

Double row bearings. The bearing inner ring and outer ring is separable structure. Inner ring or outer ring without blocking

Edge of cylindrical roller bearing, which is made to the axial circle and the outer ring can move relatively, so

Can be used as a free end bearing. , have double guard on either side of ring and outer ring, the other

One side of the ring has a single guard cylindrical roller bearing, can withstand a certain degree of a

A direction axial load. General use of stamping steel cage, or keep the copper alloy car system

Frame. But there are also part of using polyamide forming keep frame.

Cylindrical roller bearing features:

1. The rollers and raceway for the line contact or offline access, radial load capacity is large, suitable for under heavy load and shock load.

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

3. N and NU type axial movement, can adapt 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 processing the demand is higher, bearing outer axis relative deflection after installation to kept under strict control, so as not to cause contact stress concentration.

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

Main application: large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery
