xirodur® B180 | The all-rounder with J3 cage
High speeds lead to high centrifugal forces of the balls in the bearing. As a result, the balls are accelerated outward. The cage material requires a certain strength, otherwise the cage pockets expand and the balls have more clearance or freedom of movement. As a result, the balls can no longer hold themselves correctly in position, leading to higher wear and correspondingly earlier failure of the bearing. In addition to reinforcing materials, which increase the strength of the cage material, sliding friction occurs between the balls and the cage. Solid lubricants improve the sliding behavior. For these reasons, we resort to iglidur materials for a cage material. These contain improved additives to improve the strength and sliding properties.

Tolerances and measuring system:
The tolerances for inner and outer diameters depend on the size. These are often approx. ±0.05 mm to the nominal dimension. The bearing rings are usually injection molded and naturally exhibit a certain ovality. For this reason, the caliper gauge is used to measure 90° to the injection point (if present) over the entire width of the bearing. The dimensions and tolerances are designed to meet an easy press fit by hand when using a H7 mounting as well as shaft h6. Additional axial securing by means of a circlip (shaft) and snap ring (housing) is recommended to prevent axial displacement.
Mounting recommendation:
1. mounting (tolerance H7)
2. front side (balls visible)
3. rear side (cage visible)
4. press in ball bearing with front side first
5. mount shaft (tolerance h6) with chamfer
6. an axial safety device must be provided
