Single row tapered roller bearings, inch sizes, designed to accommodate combined radial and axial loads and provide low friction in operation. The inner ring, including the rollers and cage, can be mounted separately from the outer ring.
These detachable and interchangeable parts facilitate installation, removal and maintenance. Rigid applications of bearings are achieved by mounting one single row tapered roller bearing on top of another and applying preload.
High radial and axial load carrying capacity
Accommodates axial loads in one direction
low friction and long service life
Separable and Interchangeable Components
Double row/single row tapered roller bearings are mainly used in gearboxes, lifting equipment, steel rolling mills and for mining machinery, such as pit boring machines.
In the front wheel hub of the car, the small size of double row tapered roller bearings are used
Four-row tapered roller bearings four-row tapered roller bearings used in large cold, hot rolling mills and other heavy machinery. Mainly used in heavy machinery.
The most amount of tapered roller bearings is single row tapered roller bearings. Single row tapered roller bearings can bear radial load and single direction axial load.
The ability to bear axial load depends on the contact angle, that is, the outer ring raceway angle, the larger the angle, the greater the axial load capacity.
Single row tapered roller bearings have an outer ring, its inner ring and a set of tapered rollers by the basket-shaped cage into an inner ring assembly. The outer ring can be separated from the inner ring assembly
The outer ring (or inner ring) of double row tapered roller bearing is a whole.
Two inner ring (or outer ring) small end face is close to the middle of the spacer, clearance is to rely on the thickness of the spacer to adjust,
also available spacer thickness to adjust the double row tapered roller bearing preload. (Slightly larger than the hole fit form.)
