Taper roller thrust bearings enable axially very compact bearing arrangements to be produced which can carry very heavy axial loads, are insensitive to shock loads and are stiff.  We produce single and double direction taper roller thrust bearings.

Taper roller thrust bearings are produced with the “logarithmic” contact profile between raceways and rollers to guarantee optimum stress distribution in the bearing, thus enhancing bearing life.

The taper roller thrust bearings with cage are of separable design so that the two washers and the roller and cage thrust assembly can be mounted separately and easily.

Single direction taper roller thrust bearings:

We produce single direction taper roller thrust bearings in two designs which differ in the execution of the washers.

Bearing of the one design have shaft and housing washers which have the same dimensions. These washers both have a tapered raceway and one retaining flange. Bearings of this design are to be preferred where very heavy axial loads occur as, for example, in the swivels of drilling rigs or in crane hooks. The bearings have a cage which is centred on both washers.

Bearings of the other design have a shaft washer with tapered raceway and retaining flange whereas the housing washer is plane (flat). Therefore, bearings of this design are able to accept minor eccentricities of the shaft with respect to the housing bore without any detrimental influence on bearing performance. With the exception of a few sizes which have a full complement of rollers, the bearings are fitted with a roller centred cage.

Double direction taper roller thrust bearings:

   Taper roller thrust bearings of double direction type are mainly used together with multi-row cylindrical roller bearings in rolling mill applications. Those bearings with a plane shaft washer are the more popular as they are able to accommodate slight eccentricities of the shaft with respect to the housing bore, of the order of the radial internal clearance of the radial bearing with which they are used. A spacer sleeve is arranged between the two housing washers. This is dimensioned so that the cover screws of the chock can be fully tightened and no special spring adjustment of the bearing is required.

    As the double direction taper roller thrust bearings are normally mounted with a loose fit on the roll neck as well as in the chock, the shaft washer of most bearings has one or two locating slots. It is then possible to prevent the shaft washer from rotating on its seating by using keys which engage the slots or by other similar means.

Misalignment:

Taper roller thrust bearings with plane washers cannot accept any misalignment of the shaft with respect to the housing nor any errors of angle of the support surfaces in the housing and on the shaft.

Tolerances:

The bore and outside diameter tolerances of single and double direction taper roller thrust bearings with very few exceptions are produced with normal tolerances. The tolerances for the height and the running accuracy differ.

Cages:

    Those taper roller thrust bearings which do not have a full complement of rollers are fitted with machined brass cage or steel pin-type cage.
