Good quality Split Roller Bearings - Single Row Cylindrical Roller Bearings – Chengfeng Bearing

Features

One of the rib rings and rollers is attached to the cage assembly and can be separated from the other ring. Easy to install and remove.
Type N
N-type bearings have ribs on both sides of the inner ring and no ribs on the outer ring. The inner ring, rollers, and cage can be separated from the outer ring. Axial displacement of the shaft in both directions relative to the bearing housing can be allowed to bear radial loads.
NU type
NU type bearings have ribs on both sides of the outer ring and no ribs on the inner ring. The outer ring, rollers, and cage can be separated from the inner ring. Axial displacement of the shaft in both directions relative to the bearing housing can be allowed to bear radial loads.
NJ type
NJ type bearings have ribs on both sides of the outer ring and ribs on one side of the inner ring. It can be axially positioned in one direction and bear a certain degree of unidirectional axial load.
NF type
NF type bearing has double rib on the inner ring and single rib on the outer ring, which can be axially positioned in one direction and bear a certain degree of one-way load.
NUP type
NUP type bearings have flanges on both sides of the outer ring and a rib and a separable retaining ring on one side of the inner ring. It can be used as a fixed end bearing for axial positioning in both directions, bearing radial loads and a small amount of bidirectional axial loads.
NU+HJ type
The NU type bearing is used in conjunction with the HJ angle ring, which can be used for axial positioning in one direction.
NJ+HJ type
The NJ type bearing is used in conjunction with the HJ angle ring, which can be used for axial positioning in two directions.
NCLV type
The NCLV type bearing has no ribs on the outer ring but has double lock rings, and the inner ring has double ribs, no cage, and a large number of rollers. Compared with other cylindrical roller bearings of the same size, it can withstand larger radial loads. But its limit speed is low. The inner ring and outer ring of this kind of bearing cannot be separated and cannot be installed separately, which can limit the axial displacement of the shaft or the shell in two directions within the axial clearance limit of the bearing.
NJV type
NJV type bearing has a single rib on the inner ring and a double rib on the outer ring, no cage, full of rollers, and the outer ring and roller group can be separated from the inner ring. It can withstand large radial loads, but the limit speed is low, it does not limit the axial displacement of the shaft or the housing, and cannot withstand axial loads.
NCFV type
NCFV type inner ring with double rib, outer ring with single rib, no cage, full of rollers, the outer ring without ribs is equipped with an elastic retaining ring to prevent the rollers from slipping out and keep the bearing as one. Compared with other cylindrical roller bearings of the same size, it can bear a larger radial load, but its limit speed is lower, which can limit the axial displacement of the shaft or housing in both directions within the axial clearance limit of the bearing .
Cylindrical roller bearings have a large radial load carrying capacity and are suitable for bearing heavy loads and shock loads, as well as for high-speed rotation. Split cylindrical roller bearings and heavy duty full complement cylindrical roller bearings are available.

Application：

Such bearings are mainly used in medium and large electric motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading machinery and various industrial machinery.

Size range:

Single row cylindrical roller bearings:
Inner diameter size range: 25mm~1900mm
Outer diameter size range: 52mm~2300mm
Width size range: 15mm~325mm

Tolerance: The product accuracy has ordinary grade, P6 grade, P5 grade, and P4 grade products can also be processed if the user has special requirements.
Radial clearance
The standard product of single row cylindrical roller bearings has a basic set of radial clearances, and 3 and 4 sets of clearances are also available.
Bearings with radial clearance larger or smaller than the standard value can also be produced according to user requirements.

cage
Single row cylindrical roller bearings mostly use car-made solid cages, stamping cages, nylon frames, etc.
