Type ofbearings and their functions

As shown above, the Black Oxide coating helps reduce friction during startup, and the Dielectric Gray Alumina coating can be added to non-raceway surfaces to form an electrical insulation barrier.

Coating a bearing significantly reduces the scuffing and wear associated with starting and stopping the bearing and eliminates the liner's chemical reaction and opposing metal bearing components.

Bearings are an essential part of the machinery. A bearing's goal is to ensure motion is regulated in a moving part and help reduce friction.

3 main typesofbearings

This article discusses bearing types/classifications and the remanufacturing process that provides a bearing equal to or better than the original.

When selecting a bearing for an application, there are considerations to keep in mind, including friction, temperature, and lubrication.

Bearingtypes and names

Like cylindrical roller bearings, needle bearings can be made with or without a cage; if they have a cage, they can tolerate very high speed, but if they don't have a cage, they can support significant radial or axial load.

The cylindrical roller bearings have a high radial load capacity and are suitable for high speeds. They are in linear contact with the raceways.

There are five types of rolling elements; Ball, Cylindrical, Spherical, Tapered, and Needle. Ball and roller bearings are classified according to load conditions.

A plain bearing is the simplest type of bearing. It is made of a bearing surface and no rolling element. According to IBTINC, while they vary in shape and size, these bearings function as "a band of close-fitting material that encloses and supports a moving member, or forms a “sleeve” around the shaft."

There are many types of linear bearings on the market. The most common types are linear roller, cam follower, ball spline, flat ball cage, hydrostatic, ball bushing, and the crossed roller.

The fatigued surfaces result from repeated deformation between the roller and raceways. This action's stress cycle is a load and speed function and causes high stresses at the roller and raceway contact.

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the moving parts. Two types of ball bearings are angular contact and radial. The difference between the two, angular contact has a higher speed rating than radial because of the balls' constant contact to both rings.

"Tapered roller bearings are known for their ability to support radial, axial, and combined loads (both simultaneously)," according to Direct Industry. Due to their rigidity, the loads can be hefty.

Bearings Manufacturing Company offers the same solution; to keep your business moving forward and reduce friction. Machine failures are unpredictable, and if you don’t have the backup bearings you need, you may be stuck with long-lead times, causing you to waste time and money. At BMC, you get a one-stop solution for all your bearings needs, including modification, manufacturing, and repair.

The savings result from using the existing races as raw material for the remanufactured bearing. The savings can be substantial while providing a bearing equal to or better than the original. The savings is not only in money but in time, as the raw material is already delivered.

Typically, bearings have precision-made rollers, pins, or balls enclosed in a cage or a frame to rotate around its axis. When the load is placed on it and moved, the rollers or balls rotate, and the load moves forward effortlessly.

Generally, such damage runs to a depth of .002 inches or less. The material at the contact area of the roller and the raceway is fatigued by a bending action. If the operation continues until the material stress limit is reached, the fatigued contact area will be the nucleus for coarse-grain spalling.

The remanufacturing process provides customers with a bearing equal to or better than the original. This requires removing the fatigued material on the raceways and the rollers and calculating new internal geometry.

The remanufacturing process is as complex as new manufacturing with respect to tolerances, finishes, and geometry. By grinding away the fatigued material to create new contact surfaces on the raceways, we can re-engineer the internal geometry and manufacture new rollers. This process produces a remanufactured bearing that is comparable to new. Calculations, dimensions, angles, and finishes meet the accuracies of a new bearing.

The Cross Roller Ring is a roller bearing with high rotation accuracy. Because it has orthogonally arranged cylindrical rollers, it can bear loads in every direction. The main requirements in such applications are high repeatability, durability, and low friction.

Specialty Coatings can be applied to rolling bearing component's surfaces without forming a material bond, for example, by diffusion, between the coating and base material.

Machine failures are unpredictable, and if you don’t have the backup bearings you need, you may be stuck with long-lead times, causing you to waste time and money.
