Technical Information: Ball bearing types, selection

23 rows· Ball Bearings 1.0 Introduction Ball bearings are used widely in instruments and machines in order to minimize friction and power loss. While the concept of the ball bearing dates back at least Leonardo da Vinci, their design and manufacture has become remarkably sophistied. In the following we shall review their basic characteristics.

Bal-tec - Ball Material Selection

Ball Screws. Ball screws are very similar to ball bearings in that they generally use either chrome steel or type 440C hard stainless steel. A peculiarity of ball screws is that they typically have a load ball and the next ball is a .001-inch undersized spacer ball, and so on.

Deep groove ball bearings | SKF

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

What materials are used to make ball bearings?

Most ball bearings are made of a type of steel known as high carbon chromium steel, often called chrome steel. This is used for reasons of cost and durability. Bearings are also made from other materials such as stainless steel, ceramics and plastic. Chrome steel will corrode if exposed to moisture so, where corrosion resistance is needed
