When engineers in Texas design equipment, they always look at what bearings they will require. Bearings are the devices that make the movement of a machinery possible. They also prevent two parts or more from clashing and damaging each other. This is particularly important when dealing with equipment consisting of a rotating and stationary part. Pillow block bearings make it possible for the unification and smooth functioning of these disparate components.


For a pillow block bearing to produce the correct result, its inner and outer sleeve, separated by the actual bearings, must perform differently. The former turns with the shaft; the latter remains anchored. Not only do the bearings provide separation for friction minimization, but they also afford the shaft structural support. It accomplishes this without obstructing the rotation of the shaft.

The use of bearings inside a pillow shaft creates opportunities for many industries. In fact, pillow blocks find employment commonly in diverse applications within manufacturing and transportation sectors.

Pillow Block Bearings: Specifications

Selecting the proper bearings for a pillow block relies on understanding specific factors. These consist of the following:

 * Shaft diameter
 * Shaft height
 * Shaft size
 * Maximum load
 * Maximum speed

When the bearings and the pillow blocks correctly match the application, they prove to be reliable performers, functioning reliably in accordance with their specified demands by Texas customers.

The choice of the appropriate bearings is an integral part of the engineering design process. The selection of these small devices, and specifically pillow block bearings, depends upon the intended function. Engineers and operators in Texas select their bearings using their knowledge of shaft size, height and diameter as well maximum load and speed. They consider the material of the shaft and bearings. When combined with proper maintenance – including lubrication when necessary, the result is an industrial or construction application that is functional successful while exhibiting longevity and durability.
