SUNBEARING 30303 Tapered Roller Bearing Silver 17*47*15.25mm Chrome Steel GCR15

Product Description

Tractors Metric Series 30303 Tapered Roller Bearing

Tapered roller bearings have tapered inner and outer ring raceways as well as tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. 

The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e, the larger the value of the larger the contact angle. The type of bearing is divided into a single column, double row, and four-row taper roller bearings according to the number of roller bearings. 

Single row tapered roller bearings can bear radial load and single direction axial load. When bearing the radial load, the bearing will produce an axial component, so it needs to be balanced by another bearing that can bear the axial force of the reverse direction.

Tapered bearings for the construction machinery, precision machine tools, agricultural machinery, heavy trucks, automobiles, the use of the best choice, each set of tapered bearings can guarantee you to use 100,000 kilometers of service life, for you to reduce the number of maintenance bearings, to bring you more profits.
