Product description

Cylindrical roller bearings are separable, easy to mount and dismount especially more outstanding when they are used on bearings requiring clearance fits between inner and out rings with the shaft and housing. Cylindrical roller bearing is contacted with the fair line between the rollers and the raceway, which is of elimination of edge stress. Comparing with the ball bearings with same boundary dimensions, cylindrical roller bearings have larger radial carrying capacity.
Comparing with structure, this type of bearing is more suitable for high speed rotation.
Structures
1. N0000 type cylindrical roller bearings without rib on outer ring and NU0000 type cylindrical roller bearings without rib on inner ring
These types of bearings can carry large radial load, rotate at a high speed, no limit to axial displacement on shaft or housing, but cannot withstand axial load.
2. Cylindrical roller bearings with ribs on both inner rings and outer rings
NJ0000 and NF0000 types of bearings can allow axial displacement on the shaft or housing and carry little single-direction axial load; NU0000+HJ0000types, NJ0000+HJ0000 types and NUP0000 type bearings can allow two-direction displacement within axial clearance range on the shaft and housing and carry little double-direction axial load.
3. Other bearings
RN0000 type bearings without outer rings are applicable to the parts with limitation on radial sizes.The hole neck surface can be directly used as raceway surface, the hardness, processing precisionand surface roughness should be similar to those of ring raceway.NAL0000 type and NNAL0000 type of long cylindrical roller bearings with double ribs on outer ringsare applicable to petroleum machinery.Double-row cylindrical roller bearings NNU0000 type and NN0000 type.Four-row cylindrical roller bearings types FC, FCD and FCDP are mainly applicable to heavy dutymachines, such as rolling mills
Cage materials
Cylindrical roller bearings adopt copper (steel) or pole coupled cages.

Deep Groove Ball Bearing

Deep groove ball bearings are designed as non-separable bearings with the characteristics of simply designed structures; low friction coefficient and high limit rotational speed. They can mainly carry radial load and certain axial load. When the radial internal clearance increases, the bearings have ...read more

Angular Contact Ball Bearing

Angular contact ball bearing have high limit rotational speed, they can carry radial load and axial load simultaneously, they cal also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Structures 1. Separable ...read more

Tapered Roller Bearing

Tapered roller bearings are mainly suitable to carry combined load--- radial load and as well as axial load; while steep angle tapered roller bearings (27°-30°) can carry the combined load dominated by the axial load. The tapered roller bearings are separable bearings, their internal assemblies and outer ...read more

Spherical Roller Bearing

Spherical roller bearings A self-aligning roller bearing is composed by an inner ring with a double raceway, an outer ring with a spherical surface, double-row spherical rollers and a cage. The outside raceway center is in accord with shaft center; all have self-aligning function, which can compensate ...read more
