Ball bearings | Choosing the right bearing
A bearing is a mechanical component whose function is to guide a rotating assembly. The bearing therefore allows the rotation of one element relative to another. Bearings are therefore high-precision parts that allow equipment to move at different speed levels by efficiently transporting notable loads. They must offer high precision and durability, as well as the possibility of working at high speeds with minimal noise and vibration. This type of device is...

How to choose this product
ball-bearing

Like all rolling bearings, ball bearings consist of two concentric races and rolling elements held in place and separated by a cage. Here, the rolling elements are spherical. Different types of bearing are used for different load levels.

Applications

Extremely common in mechanical assemblies with a rotating shaft, ball bearings exist in a wide variety of sizes and shapes for use in extremely diverse moderate-load applications.

Technologies

Ball bearings are composed of two races holding one or several rows of balls. Load capacity depends on bearing type: angular contact, four-points contact, etc. They can be made of different materials, including ceramic, plastic and steel. Available with or without an integrated seal, some models are pre-lubricated.

Advantages

- Rotation velocity

Disadvantages

- Fragility
- Life span
