Advantages of high-performance bearings for automotive manufacturers

high-performance bearings

Bearings enable smooth, low-friction motion. In a perfect world, they would all be super light, extremely compact, maintenance-free, quiet, and durable. Unfortunately, the world isn’t perfect, but high-performance ball bearings can come very close. Here are some pointers on their use for automotive manufacturing.

Rolling or plain bearings for automotive applications

Plain bearings are those with a smooth, low-friction surface. They are used in the crankshaft, camshaft, and connecting rod areas because they can support very high loads. Elsewhere in the car, rolling bearings take care of friction reduction.

These use balls or rollers that separate an outer and inner race. A cage holds them in place and allows them to roll freely when the inner or outer race rotates. This rolling motion minimizes friction.

High-performance bearings in automotive manufacturing

Rolling bearings can be designed for radial loads, axial loads, or both. Load capacity is proportional to the number of balls or rollers and their diameters. High-performance bearings pack high performance into a small volume. They can be designed for a wide speed range, including applications where the speed varies rapidly. In addition, bearing designers can incorporate self-aligning features, which simplifies installation in mechanisms and reduces costs.

Other features of high-performance bearings include their quiet, smooth-running, and long life. This results from the materials used and the precision with which they are manufactured. They can also be designed to be virtually maintenance-free.

Advantages of using high performance automotive bearings.

1. packaging/space/envelope. High-performance bearings can be designed to take up very little space.

2. perception of quality. The movement will be quiet and smooth, giving the driver the feeling of being in a high-quality vehicle.

3. durability. Careful selection of materials and careful design and engineering analysis ensure that the bearings can exceed the life of the vehicle.

4. simplification of assembly. The self-aligning ability can allow simplification of construction elsewhere and facilitate the assembly of the complete mechanism.

5. lightweight. Careful design and rigorous material evaluation and selection result in bearings that offer high performance for their size and mass.

Example of automotive applications

High-performance automotive bearings are used in all areas of the modern automobile. Seat rails are one example. This application requires high load capacity while providing exceptionally smooth and quiet movement. And, as with all automobiles, weight must be minimized.

A second example is steering column bearings. Drivers take it for granted that the wheel will turn smoothly, but space for the bearing is often severely limited. Again, a high-performance bearing that offers a good feel and high load capacity in a small package is the answer. For details, please visit:
