SKF Bearing NJG 309 VH

Product description of SKF Bearing NJG 309 VH

SKF Bearing NJG 309 VH SKF single row full complement cylindrical roller bearings incorporate a maximum number of rollers, as they are not equipped with a cage.

The basic SKF assortment provided here includes:
The SKF standard assortment of single row full complement cylindrical roller bearings provided here includes NCF and NJG design bearings. They are used to locate the shaft axially in one direction and eventually to accommodate axial displacement of the shaft relative to the housing in the opposite direction.
NCF design bearings. have two integral flanges on the inner ring and one on the outer ring have a retaining ring in the outer ring, on the side opposite the integral flange, to hold the bearing together The retaining ring should not be loaded axially during operation.
NJG design bearings.comprise the heavy 23 dimension series are intended for very heavily loaded, low-speed applications have two integral flanges on the outer ring and one on the inner ring.
have a self-retaining roller complement Therefore, the outer ring with the roller complement can be separated from the inner ring without having to take special precautions to prevent the rollers from falling out. This simplifies mounting and dismounting.
Matched bearings, are combined so that any difference in cross-sectional height of the bearings used in a matched set lies within a very small tolerance range This tighter tolerance is a precondition for equal load sharing between the bearings.
can be supplied as:
sets of two bearings (designation suffix DR)
sets of three bearings (designation suffix TR)
sets of four bearings (designation suffix QR)
SKF Bearing NJG 309 VH, Cylindrical roller bearings are produced in many designs, ISO Dimension Series and sizes. The vast majority are single row cylindrical roller bearings with a cage. These bearings are an excellent choice for applications where there are particularly heavy radial loads combined with high speeds, especially if there is a limited amount of axial displacement of the shaft with respect to the house-ing as a result of thermal elongation.As axial displacement takes place within the bearing, there is practically no increase in friction as the bearing rotates.

SKF Bearing NJG 309 VH, Single row cylindrical roller bearings are separable, i.e. the ring with roller and cage assembly can be mounted independently of the other ring. This simplifies installation, particularly if an interference fit is required for both rings, Single row cylindrical roller bearings with a cage are produced in many designs, differing primarily in the configure-ration of the flanges. The rollers are always guided between integral flange son one of the rings. The ring with the integral flanges together with the cylindrical roller and cage assembly can be withdrawn from the other ring.The most popular single row cylindrical roller bearings are those of the NU, N,NJ and NUP designs.
