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
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.
1.High quality and good service
2.Less friction and low noise
5. Small order accepted
6.Excellent antitrust technology
8.Large size range:inner diameter from 80mm-1360mm.
9.Variations of structure:NU,N,NJ,NF,NUP,NH,NCLV...,NB,
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.
