Four row Tapered Roller Bearings

Four row tapered roller bearing inner ring with the neck roll and generally with the gap, when the first installation of bearing load bearing box, and then put into boxes bearing journal.

Four row tapered roller bearings and bearing outer ring also used moving boxes with holes, the first load bearing outer ring A box (see Figure 2). Factory in the outer ring, as well as inside and outside the inner circle are printed every other character symbols, characters must be installed when the symbols are arranged in order of load bearing box. Can not be any swaps in order to prevent the bearing clearance to change.

Bearing all the parts are put into boxes, and within the inner circle separated, and the outer ring outside the ring every axial

Measurement end with the outer ring bearing cover the width of the gap between the board to determine the appropriate thickness of the gasket.

Workroom display:   

double row taper roller bearings can take up heavy loads and are stiff.Suitable for combined radial and axial loads, they locate axially the shaft in both directions with the stated axial end play  or given preload.

The basic styles are two-row converging TDI configuration and two-row diverging TDO configuration.Rings and rollers are made of high chrome through hardening steels or case hardened carburizing alloy steels depending on the application.Cages for CIE double row taper roller bearings are stamped pressed steel. A steel pin-type cage, which allows a larger complement of rollers for higher capacity, is also available.

This style of bearing set simplifies design and reduces the danger of bearing clearance changes due to axial shaft expansion.

It is important the definition of the proper internal play related to the application.

taper roller bearings can carry only single direction axial loads. Under pure radial loads, an axial force is induced within the bearings so that they cannot be used singly and a second bearing is required.A correct operational clearance or preload has to be identified for the correct performance and reliability of the application.
