Specifications of igubal® spherical ball materials

Every igubal® bearing is wear-optimised. However, there are materials that are specifically suitable for various applications. In addition to their service life and price level among other things, the materials differ due to temperature and load ranges as well as the usability in conjunction with special shaft materials.

All igubal® materials have the following specifications:

  • Lubrication and maintenance-free
  • Lightweight
  • Good price-performance ratio
