Superior Performance in Horizontal Shaft Applications
Tapered thrust bearings have been found to have superior performance in horizontal shaft applications. The self-centering action of the rollers helps counteract the gravitational effect of the roller assembly. This reduces the possibility of the roller assembly contacting the shaft.

Steel
The plates and rollers are made from case hardened carburizing bearing grade steel. Upon request we can manufacture the components from CEVM or VIMVAR grades of material.

Precision Ground Inner and Outer Plates
All thrust plates are accurately ground for flatness and parallelism of roller riding and backing surfaces. Locating diameters are ground to obtain an accurate fit on the shaft or in the housing. The surfaces of the plates are ground to provide a long operating life. The guide rib on the tapered plates is spherically ground to match the roller and reduce friction. All tapered thrust plates are designed to be used with a full complement of rollers. Therefore, making it possible to supply this version for any size. Rollway tapered thrust pates are manufactured from Carburizing Bearing Grade Steel. The surfaces are precision ground to ABMA standards. Unlike the cylindrical thrust, these plates can be used as either the shaft or housing plate.

Precision Ground Tapered Rollers
All rolling elements are precision ground and graded to provide an even distribution of load over the contact surfaces. Rollers are crowned for optimum contact stress patterns by reducing the end stress between the roller and the thrust plates. The large ends of the rollers are spherically ground. This provides controlled contact between the rollers and the guide rib, thus enhancing the flow of lubricant. These rollers are manufactured from Carburizing Bearing Grade Steel.

Machined Brass Retainer
The TTHD taper thrust bearing retainers are machined from a single piece of centrifugally cast brass. The retainer is designed to pilot on the thrust plates’ flanges. The roller pockets are accurately machined at right angles to the thrust force which will be applied to the bearing. Due to their design, tapered thrust bearings provide a true rolling motion. This is in contrast to cylindrical thrust bearings, whose rollers tend to have a minimal amount of slippage due to the fundamental design.

Pin through Steel Type Retainer – T-Flat Type
The T-Flat retainers are “pin through” style (pins extend through the center of the roller). The retainer consists of two steel rings through which the hardened steel pins are secured. An alternate design is a retainer machined from a single piece of centrifugally cast brass with each roller retained by two pins.
