High Quality Material & Low Noise Of Cylindrical Roller Bearing
- Nov 17, 2016 -

Key Specifications/Special Features:

·         Structure: cylindrical

·         Cylindrical roller bearing:

o    Single roller, double roller and four roller bearing

o    Single roller: N, NU, NJ, NF, NUP, NFP, NH series

·         Single row cylindrical roller bearing can be classified in NU, NJ, NUP, N, NF

·         Inner ring outer ring are separable

·         Can bear axial load from one direction

·         Generally made of steel stamping or brass cage and some of them are using cage of formed polyamide

·         Double roller: NN, NNU, NNF series

·         Double roller bearing

·         They are separable, which means ring with complete flange, roller and cage can be installed with other rings, or all the bearing components can be installed separately, which is favorable for stalling, checking and maintaining

·         Four roller: FC, FCD series

·         Four row cylindrical roller bearings are almost used for roller neck of mill housing, rollers and rolling machines

·         Compared with other roller bearing, these bearing are characterized by low friction

·         They are always interference fitted on roll necks especially application to rolling machines which rolling at a high speed

·         Single roller bearing have some types:

o    Single row cylindrical roller bearings without inner Ring rib (NU type)

o    Single row cylindrical roller bearings with single inner ring rib( NJ type)

o    Single row cylindrical roller bearings with single inner ring rib and loose rib (NUP type)

o    Single row cylindrical roller bearings without out ring rib ( N type)

o    Single row cylindrical roller bearings with single inner ring rib and thrust separate ring(NJ+HJ type)

o    Single row cylindrical roller bearings with single out ring rib (NF type)

·         Double row cylindrical roller bearing types:

o    NN: outer ring without flange, the inner ring of the two guard intermediate in the guard

o    NNU: both sides of outer ring have flange, intermediate have flange, inner ring without flange

o    NNF: double full cylindrical roller bearing

·         Four roller bearing types:

o    FC: double outer rings, single inner ring, without ribs

o    FCD: double outer rings, double inner rings, without ribs

o    FCDP: double outer rings, with center and loose ribs, double inner rings, without ribs

·         Cylindrical roller bearing feature:

o    Roller and roller way for line contact or repair referrals contact, radial bearing capacity is big, is designed to withstand heavy loads and shock load

o    Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearing

o    N type and NU type can be axial movement, can adapt for thermal expansion or installation error caused by the shaft and housing relative position change, can make free end bearing use
