Roller bearings can be used in all types of tracks, and used for cam drive, conveyor systems, etc.. These bearings have a thick outer ring that allows them to adapt to high radial loads while reducing deformation and bending stresses.
The running surface of the outer ring is a convex spherical surface. This is useful for applications that may have a relative angular deviation from the orbit, or the need to minimize edge stresses. In addition to single row ball roller bearings, roller bearings can also be equipped with cylindrical (flat) outer ring running surface.
The roller bearing provided by SKF has been filled with grease, and has a seal, can be installed at any time.
SKF provides a variety of types and design forms of roller bearings, suitable for a variety of conditions and applications. Its type covers:
Ball roller bearing
Single row ball rolling body roller bearing SKF single row cam roller based on 62 series deep groove ball bearing. These bearings have been filled with grease, and on both sides of the steel skeleton reinforced nitrile rubber seal.
Double row ball rolling bearing
SKF double row cam roller is based on 32 series double row angular contact ball bearings, with a 30 degree contact angle. Supply has been filled with grease, can be selected on both sides of the fixed on the inner ring of the steel plate on the dust cover (model suffix -2Z); or on both sides of the RS contact seal (type suffix 2RS1).
Cylindrical roller bearing
SKF cylindrical roller bearing, the internal design of the needle roller bearings or cylindrical roller bearings based on their thick outer ring, so that it can adapt to high radial load, while reducing the deformation and bending stress.
The running surface of the outer ring is a convex spherical surface. However, it is also possible to provide roller bearings with cylindrical (flat) running surfaces. These are pre packed grease quick mounting units for all types of cam drive and conveyor systems.
SKF cylindrical roller bearing:
Without edge
With side
Bolt type cylindrical roller bearing
Bolt type cylindrical roller bearing without inner ring, replaced by a threaded solid studs, so that you can use six nut quickly and conveniently the cam follower mounted to the machine parts corresponding to the.
SKF bolt cylindrical roller bearing has three basic design:
KR design
NUKR design
PWKR design
All three types of cylindrical roller bearings have the same main dimensions. They differ in their internal design, which allows them to be used in different operating conditions. For ball bearings and roller bearings, the bearing size refers to the diameter of D, and for the cam follower, the size is D.
All forms of design on the stem with a concentric seat or an eccentric sleeve. Between the eccentric sleeve and the stem is fit, the positioning tolerance related components with low requirements. Adjustable eccentricity values listed in the product list. The eccentric sleeve is represented by the E at the end of the basic model.
