Unique Design of Grease-Free, Plastic Ball Bearings

Why is igus® ball bearing design unique?

  1. Inner and outer ball bearing races: the suitability of a xiros plastic ball bearing is determined by the materials of the two races. Our low-friction ball bearings are made of high-performance plastics with different material properties, which means that they can be used in many applications and service life can be maximized.
  2. Ball bearings cage: the cages of the xiros plastic ball bearings are perfectly tailored to the materials of outer and inner ball bearing races regarding resistance to chemicals and temperature.
  3. Ball bearings balls: in addition to steel balls igus offers polymer ball bearings with balls made of glass or plastics.  Glass balls are used to give a metal-free and chemical-resistant solution. By using polymer balls ball bearings are particularly lightweight and quiet.  Steel balls (stainless steel) are particularly cost-effective and temperature-resistant.
