Ball & Roller Bearings

Texas Bearing Services manufactures and distributes all types of ball and roller bearings up to twenty four feet in diameter. Serving OEM clients, distribution, aftermarkets and end users all over the world.

Slew ring bearings

Four point contact

Four point contact - Four point contact ball bearings are radial single row angular contact ball bearings with races that are designed to support both axial and radial loads in either direction. Available with internal gear teeth, external gear teeth or gearless designs.

Eight point contact

Eight point contact – Eight point contact ball bearings are radial double row angular contact ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Available with internal gear teeth, external gear teeth or gearless designs.

Three row roller

Three row roller – three row roller bearings are designed with three independent rows of rollers to accommodate a combination of axial and radial overturning moment loads. Available with internal gear teeth, external gear teeth or gearless designs.

Cross roller

Cross roller – Cross roller bearings are designed with multi-directionally installed cylindrical rollers. They are designed to accommodate radial, axial and overturning moment loads with a compact design footprint.

Ball Bearings

Angular contact

Angular contact - An angular contact ball bearing uses axially asymmetric races. Axial loads pass in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each.

Axial thrust ball bearing

Axial thrust ball bearing - Thrust ball bearings, composed of ball bearings supported in a ring, can be used in high thrust applications where there is high axial load. An axial load is transmitted directly through the bearing, while a radial load is poorly supported and tends to separate the races.

Deep groove ball bearings

Deep groove ball bearings - In a deep-groove radial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.

Tapered roller bearings

Tapered

Tapered roller bearings are designed to accept large axial and radial forces. They use a combination of cups and cones with angular shaped rollers to transmit the loads. There are a multitude of configurations including Single row, double row and four row.

Cylindrical roller bearings

Cylindrical

Cylindrical roller bearings utilize cylindrically shaped rollers as their rolling element. They are many designs available including single row, double row, and full complement designs. They can be configured in an axial or radial thrust design.

Spherical roller bearings

Spherical

Spherical roller bearings are designed with spherically shaped rollers that allow for misalignments. These bearing typically support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. Most are designed with two sets of rollers allowing them to accommodate heavy axial and radial loads.
