Features:
In contrast to standard bearings, the cross-sectional dimensions in each series are designed to be fixed values. The cross-sectional dimensions are constant in the same series but do not increase with internal dimensions. Therefore, the series of thin-section bearings is also known as the same section thin-section bearings. By using the same series of thin-section bearings, the designer can standardize the same common parts. Thin-section bearings with large cross-sections can be replaced by hollow shafts with large diameters instead of small-diameter solid shafts  such as air, water, and wire, which can be provided by hollow shafts to make the design simple. Thin-section bearings can save space, reduce weight, significantly reduce friction, and provide good rotation accuracy. The use of thin-section bearings can reduce the external dimensions and reduce production costs without compromising bearing performance and service life.

KNC thin-section bearings are available in seven open series and five sealed series with bore diameters from 1 inch to 40 inches and cross-sectional dimensions in the range of 0.1875 x 0.1875 inches to 1.000 x 1.000 inches. There are three open bearings: radial contact, angular contact, four-point contact. Sealed bearings are divided into: radial contact and four-point contact.
