Specification:

Cylindrical roller bearing is a separable bearing,easy to assembly and dismantle,Tight fit can be use for both inner and outer rings.The corrected contact line between the rollers and raceway can reduce stress concentration.

Information of the cylindrical roller bearing

Cylindrical roller and raceway for the line contact bearings. Load capacity, the main radial load. The rolling element and ring wall friction is small, suitable for highspeed rotation. According ring without ribs, can be divided NU, NJ, NUP, N, NF and other

single row bearings, and NNU, NN and other double row bearings. The bearing is the inner, outer separable structure. Inner or

outer wall of the cylindrical roller bearings, the inner and outer rings relative to the axial movement can therefore be used as

freeend bearings. On either side of the inner and outer double wall, the other side of the ring has a single wall of the cylindrical

roller bearings, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy machined

cage. But there are also some use of polyamide forming cage.

Features of cylindrical roller bearing

1 roller and the raceway is in line contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and

shock load.

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

3. N NU type pattern and to be axially movable to adapt to the mounting shaft due to thermal expansion or due to the relative

errors with the housing position changes, can be used for supporting the free end.

4 of the shaft or housing bore machining higher, after the installation of the outer ring bearing axis relative deflection should

be strictly controlled to avoid contact stress concentration.

5 inner or outer ring detachable, easy installation and removal.

What we can do: 

1.High quality and good service

2.Less friction and low noise

3.Competitive price

4.Quick delivery

5. Small order accepted

6.Excellent antitrust technology

7.Long life

8.Large size range:inner diameter from  80mm-1360mm.

9.Variations of structure:NU,N,NJ,NF,NUP,NH,NCLV...,NB,

NU...V,NNU,NNCF,NNCL,NNCS,FC,FCD,FCDP.

10. Physical Characteristics:

1)  Cylindrical roller bearing can be separated by

single row,double rows and four rows.

2)Cylindrical Roller bearing can be submitted to high

radial load and some axial load.

3)  The rolling element of cylindrical roller bearing is

cylinder,the two ends of the external lines have the

corrective slope which can eliminate the contact stress.

4)  Cylindrical roller bearing have high rigid and apply

to machines such as rolling mills.

The main purpose

Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill,

vibrating screen and lifting and transport machinery.
