Unique Design of Grease-Free, Plastic Ball Bearings

Why is igus® ball bearing design unique?

Due to the polymers used, all xiros plastic ball bearings are permanently maintenance-free without requiring additional lubrication.

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.
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.
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.
