The main purpose of ISB elastic rings for shafts (AE) and for bores (AF) is to avoid any type of axial shifting by bearing rings or caged needle rollers. These are made from steel and guarantee minimum radial dimensions. ISB elastic rings for shafts (AES) have the same characteristics as the above mentioned rings, except with a greater radial height, guaranteeing a greater preload.

ISB elastic rings are particularly suitable for axial stability in needle roller bearings and cylindrical roller bearings.

Bores have been inserted in order to facilitate mounting operations, and the use of suitable pliers is recommended.


NBS elastic rings are used in various applications, for example:
* lifting equipment;
* industrial machinery;
* etc.
