Features of thrust bearing 51109
Thrust ball bearings consist of two precision chrome steel washers (ring) and a ball complement spaced by bronze retainer. They can be supplied with or without radius ball grooves in the rings. Thrust bearings are used under purely axial loads.Thrust ball bearings can handle loads in the axial direction only. Bearing rings mounted on the shaft are called shaft washers, and those mounted in the housing are called housing washers. Both washers contain raceways for the balls.Thrust ball bearings are available as both single and bi-directional types. The bi-directional thrust bearing incorporates a third washer and an additional set of balls. This center washer is located in the axial direction by a shaft shoulder and sleeve.Care must be taken in handling to prevent damage to the separable rings and ball assemblies.
Applications of thrust bearing 51109
live centers in lathes, lead screws, automotive clutches, kingpin supports, speed reducers
Single direction thrust ball bearings
Single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage thrust assembly. The bearings are separable so that mounting is simple as the washers and the ball and cage assembly can be mounted separately.
Smaller sizes are available with either a flat seat surface on the housing washer ( fig 1) or a sphered seat surface ( fig 2). Bearings with a sphered housing washer can be used together with a sphered seat washer ( fig 3) to compensate for misalignment between the support surface in the housing and the shaft. Sphered seat washers are available from TORRINGTON but must be ordered separately.
Single direction thrust ball bearings, as their name suggests, can accommodate axial loads in one direction and thus locate a shaft axially in one direction. They must not be subjected to any radial load.
In addition TORRINGTON also offers polymer thrust ball bearings, shown in the section "Engineering products - Polymer ball bearings".
Double direction thrust ball bearings
Double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball and cage thrust assemblies. The bearings are separable so that mounting is simple. The various parts can be mounted separately. The housing washers and ball and cage thrust assemblies are identical to those of the single direction bearings.
Smaller bearings are available with either a flat seat surface on the housing washers ( fig 4) or with a sphered seat surface ( fig 5). Bearings with sphered housing washers can be used together with sphered seat washers ( fig 6) to compensate for misalignment between the housing and shaft. The sphered seat washers are available from TORRINGTON , but must be ordered separately.
Double direction thrust ball bearings can accommodate axial loads acting in both directions and can thus serve to axially locate a shaft in both directions. They must not be subjected to radial load.
