Thin-walled isometric bearings, also known as thin-walled ferrule bearings, are highly accurate, very quiet and have a high load carrying capacity. Thin-walled ferrule bearings can be deep groove ball bearings, four-point contact bearings, angular contact ball bearings, and thin-walled bearings are mostly square in cross section. In these series, even with larger shaft diameters and bearing bores, the cross section remains the same. These bearings are therefore referred to as equal sections. It is this feature that distinguishes thin-walled ferrule bearings in the standard ISO series from conventional bearings. Therefore, a larger cross section can be selected and a more load bearing bearing can be used without having to change the shaft diameter. Thin-walled ferrule bearings can be designed to be extremely light and require very little space. Complete specifications, a large number of stock.
