What are the classifications of thin-walled bearings?

Thin-walled bearings are generally divided into rubber seal-RS, iron seal-ZZ, plane, iron clamp-K, copper clamp-M. For example: 608RS, 6914ZZ, 61926K, 61844M.

1.Thin-walled Crossed Roller Bearings

CRA series thin-walled crossed roller bearings (split outer ring type) are small and lightweight crossed roller bearings with very thin outer and inner ring walls. They are small and can withstand heavy loads, so the bearing installation parts on the equipment can be lightweight.

The inner and outer ring dimensions of the CRB series thin-walled cross roller bearings (split outer ring type) are minimized to the maximum extent. The outer ring is divided into two parts, and the inner ring is a one-piece structure. It is most suitable for places where high inner ring rotation accuracy is required.

CRE series thin-walled crossed roller bearings (split inner ring type) have a structure in which the inner ring is divided into two parts and the outer ring is a one-piece structure. They are most suitable for places where high outer ring rotation accuracy is required.

Thin-walled ring bearings are highly precise, very quiet and have a high load-carrying capacity. These ball bearings are available in three designs and are extremely small, mostly with a square cross section. In these series, the cross section remains constant even with larger shaft diameters and bearing bores. These bearings are therefore called constant cross-section. It is this property that distinguishes thin-walled ring bearings in the standard ISO series from conventional bearings. It is therefore possible to select a larger cross section and use a bearing with a higher load-carrying capacity without having to change the shaft diameter. Thin-walled ring bearings can be designed to be extremely light and require very little space.

2.Deep groove ball bearings, four-point contact bearings, angular contact ball bearings

Thin-walled ring bearings can be deep groove ball bearings (C), four-point contact bearings (X), angular contact ball bearings (E). All of these designs are available in different series. The series depends on the size of the cross section. The balls are matched to the series. Deep groove ball bearings can support axial loads in both directions as well as radial loads. Four-point contact bearings can support axial loads in both directions as well as radial loads; they therefore operate in the same way as double-row angular contact ball bearings. Angular contact ball bearings are matched with an optimal number of balls and have a contact angle of 30. They can support higher radial loads than deep groove ball bearings or four-point contact bearings and can support axial loads originating from the same direction. On special request, angular contact ball bearings can also be supplied as matched bearings. As a result, the rigidity and load-carrying capacity of these combinations are much higher than with single bearings.
