Lightweight, low-friction thin section ball bearings also offer these advantages

Thin section ball bearings are well-suited to the compact, simplified, and lightweight requirements of modern machinery's rotary mechanisms, featuring small size, light weight, and low friction. They are widely used in aerospace, precision machine tools, rotary tables, radar communications, industrial robots, semiconductor processing equipment, medical equipment, and other fields, significantly reducing equipment weight, alleviating friction, and providing excellent rotational accuracy.

Thin section ball bearings are mainly divided into three types:

1. Radial contact (L-type)

2. Angular contact (M-type)

3. Four-point contact (N-type)

The bearing rings in these series are primarily made of bearing steel and stainless steel.

Characteristics of thin section ball bearings:

Unlike standard bearings, the cross-sectional dimension of thin section ball bearings is designed to be a fixed value within each series. The cross-sectional dimension remains constant throughout the series and does not increase with the internal dimensions. Therefore, this series of thin section ball bearings is also known as constant cross-section Thin section ball bearings. By using thin section ball bearings from the same series, designers can standardize common components.

Using thin section ball bearings with large bores and small cross-sections allows for the replacement of small-diameter solid shafts with large-diameter hollow shafts. For example, air, water pipes, and electrical wires can be supplied through hollow shafts, simplifying the design.

Thin section ball bearings save space, reduce weight, significantly reduce friction, and provide good rotational accuracy. Without compromising bearing performance and lifespan, using thin section ball bearings can reduce the external dimensions of the design and lower production costs.

Seven open series and five sealed series of thin section ball bearings are available, with bore diameters ranging from 1 inch to 40 inches and cross-sectional dimensions ranging from 0.1875 × 0.1875 inches to 1.000 × 1.000 inches. Open bearings are available in three types: radial contact, angular contact, and four-point contact. Sealed bearings are available in radial contact and four-point contact.
