-------   automobile hub Bearing/Excavator bearings SF 3240

Type,Structure and Characteristics

Excavator bearings SF 3240 are desined such that their conical rollers

and raceways are arranged so that all elements of the rollerand race way

cones meet at a common apex on the bearing axis.

The rolling elements perform the real rotating movement on the raceway;

the synthesized force from the inner and outer ring raceways guides the rollers,

pressing them to the large rib on the inner ring.

Metric and inch series are considered standard and both systems are widely used.

The inner ring,rollers and cage can be separated as a unit,or the CONE,from the outer ing,

or the CUP.The CUP and cone are called sub-units,Sub-unit dimension for the nominal cup

small inside diameter and bearing contact angle,are standardized

by ISO and ABMA and are compatible between sun-units,Double row and four row bearings

are available in addition to single row in addition to single row bearings.

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 clearanceis established during mounting by the axial position of the

cone relative to the cup.

Applications

Excavator bearings SF 3240  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.
