Tapered Roller Bearings 30303

Dimension:17mm*47mm*15.25mm

Product description:

Tapered Roller Bearing has a conical inner and outer ring raceway, Tapered Roller arranged in between, all conical surface projection lines in the bearing axis to meet the same point, this design enables Tapered Roller Bearing particularly suited to bear composite (radial and axial) loads. Tapered Roller Bearings can best way to stress distribution in the Roller Raceway contact with the surface, thereby enhancing the reliability and affordability of error of perspective.

Tapered roller bearings are applied in a broad range of industries including automobile, rolling mill, metallurgy, plastic machinery, etc.

Features:

The inner and outer ring raceways and rollers of these bearings are made with a taper so that the surface planes of the raceways and roller axis meet at a point. The rollers are guided by a flange on the inner ring. Tapered roller bearings are separable, and have the following components: outer ring, inner ring and roller assembly. The non-separable inner ring and roller assembly is called the 'cone', and the outer ring is called the 'cup'. Internal clearances established during mounting by the axial position of the cone relative to the cup.

Applications:

Mainly used in motorcycle rear axle wheel hub, heavy machine tools' main shafts, big power reduction gears, axletree axle boxes, roller wheels of transportation devices, and the supporting rollers and working rollers of the rolling mills.
