Companies introduce rolling bearing cages with DLC, or Diamond-like Carbon, finishing. These steel cages coated with DLC are harder and last longer than the standard, uncoated brass variants, as well as are ideally matched to harsh operating problems. Other bearing elements besides cages can be treated with the amorphous carbon layer.
As a component of its continuous initiative to improve the performance capabilities of its moving bearings, companies investigate surface area finish technologies and utilize different cage products. Bearings that are utilized in equipment with high radial velocities, centrifugal forces, or vibrations are generally furnished with outer-ring or inner-ring assisted, largely one-piece, solid brass cages in order to reduce any undesirable impacts the cage might carry the activity characteristics of the rolling aspects. Examples of regular applications include huge end bearings, quickly accelerating gearboxes, or generator systems.

Although strong brass cages are an acknowledged requirement, they are still subject to particular operating limits. In applications with heavy loading, too much wear, abrasion of the cage guide surfaces, or perhaps mechanical failure can happen.
In order to improve the performance of radial cylindrical roller bearings and radial deep groove round bearings specifically, for demanding operating conditions company utilizes a cage made from high-strength material with an amorphous carbon finishing, the DLC coating. This increases resistance to breakage and lowers the coefficient of friction between the moving bearing shoulders as well as the cage, helping to avoid early wear or abrasion, particularly in applications where lubrication is challenging. The material of selection for the cage is steel and depending upon the layout of the born the cage may be machined solid steel with external or internal ring support. These cages are identified as necessary with the suffixes FPB or FBA.
