New lubrication-free, self-aligning plastic ball bearings
Igus is expanding its product range by introducing lubrication-free flange and pedestal bearings with plastic ball bearings. The new xiros polymer ball bearings with angular compensation were developed for maintenance-free use in conveyor belts, track rollers and deflection rollers. The light, corrosion-free and anti-magnetic bearings do not need any oil or grease, and compensate for alignment errors caused by deflection and/or tolerances. Potential applications include conveyors, automotive parts suppliers, newspaper printers, food and drinks industries, and also textile and glass production and stone processing.
Ball bearing flange and pedestal bearings are available in two materials: one for high temperatures of up to 150degC with the inner ring made of the high-performance polymer xirodur A500; and one for normal temperatures made of the xirodur B180. In both cases there is a simple, rigid version available for the low-cost sector where the balls run directly against the casing, as well as a self-aligning version in which the complete polymer ball bearing with an outer ring is integrated in a plastic spherical component. The corrosion-resistant balls are made of stainless steel or glass for maximum media resistance. The casing is made of igumid G, a particularly impact-resistant, long fibre-reinforced polymer.
The new bearings are available immediately ex-stock in 16 variants with an bore of 10mm. Currently in development are 6, 8 and 20mm versions.
