Tapered roller bearings are generally of separable design and have tapered one and cup raceways between which tapered rollers are arranged, their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load.
LEGEND tapered roller bearings have types of single row, double row and four row. The single row tapered roller bearings are able to accommodate radial load and axial load in one direction only. Under radial load, and axial component force is produced in the bearing which must be counteracted, so the bearing is normally adjusted against a second bearing. Axial load carrying capacity of single row tapered roller bearings is largely determined by the contact angle, which corresponds to the angle of the cup raceway. The larger this angle, the higher the axial load carrying capacity.
LEGEND manufactures single row tapered roller bearings with metric as well as inch dimensions. Bearings with suffix E in metric series are reinforced bearings and the main parameters have been optimized. Their rollers are more and longer than the conventional bearings. These bearings therefore have higher load carrying capacity and longer basic rating life. These dimensions of bearings conform to ISO. All the designations and dimensions of inch size bearings of LEGEND conform to AFBMA standards.
LEGEND produces double row and four row tapered roller bearings which can carry combined (radial and axial) load in which radial load is predominant and axial load in two directions. They limit axial displacements of shaft relative to housing in both directions.
In order to satisfy the special demands of customers, bearing axial clearance can be modified by using the special adjusted procedures. The load can be uniformly distributed within the bearing axial clearance limit. The bearings with this feature are usually suitable for the operation of medium of low speed.
Tapered roller bearings can be supplied with a pressed steel cage, but those with outside diameter D>650mm will be supplied with a machined steel cage. This kind of cage is welded with supporting rollers (each roller has a supporting hole in its radial center).
