Cylindrical Roller Bearings

Galaxy Bearings Limited manufacturers Cylindrical Roller Bearings. Galaxy Bearing Ltd. manufactures many types and sizes of cylindrical roller bearings, the majority being single row bearings with cage & also with a full compliment of rollers. The Galaxy Bearing Ltd. manufacturing program also included precision single and double row cylindrical roller bearings for machine tool applications and double cylindrical roller bearings for rolling mill and other heavy engineering applications as per the customer requirements. All Galaxy Bearing Ltd. cylindrical roller bearings represent the latest state of the art Bearings. The contact geometry between roller and raceway has been much improved by the introduction of the “logarithmic” profile, which provides for optimum stress distribution in the bearing. Optimized surface finishes favors lubricant film formation and the correct rolling motion of the cylindrical rollers. These improvements have considerably increased the performance of Bearings.

The rollers of single row cylindrical roller bearings with cage are guided between integral flanges on one the bearing rings. The bearing rings with integral flanges and the roller and cage assembly can be withdrawn from the other ring. This facilitates mounting and dismounting particularly where both rings have to have interference fits because of the load conditions. Galaxy Bearing Ltd. single row cylindrical roller bearings have high radial load carrying capacity and also high speed capability. They are produced in different designs, which differ in the configuration of the flanges. Bearings of the NU type have two integral flanges on the outer ring and an inner ring without flanges. Where as the N types have two integral flanges on the inner ring and outer ring without flanges. Cylindrical roller bearings of the NJ type have two integral flanges on the outer ring and one integral flange on the inner ring. So that axial location can be provided for the shaft in one direction.

Type NUP cylindrical roller bearings have two integral flanges on the outer ring and the inner ring have one integral and enabling the bearings to locate a shaft axially in both directions. NJ type bearings when used with an HJ angle ring can also be used to locate the shaft axially in both directions whilst the combination of an NU bearing with an HJ angle rings at both sides of NU type bearings as this can lead to axial compression of the rollers. The magnitude of the axial load which can be accommodate by bearings of the NJ and NUP types and by the angle ring can be determined from the information given under "Dynamic axial load carrying capacity"
