Lubricant-free with angular compensation
Igus has expanded its range even further 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 conveyer belts, track rollers and deflection rollers. The light, corrosion-free and anti-magnetic bearings do not need any oil or grease, and compensate alignment errors caused by deflection and/or tolerances. Potential applications include conveyer engineering, automotive parts suppliers, newspaper printers, food and drinks industries, and also the textile and glass production and stone processing.
The ball-bearing flange and pedestal bearings are available in two materials: One for the high temperature range 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 version which compensates angles.
In this case, the complete polymer ball bearing with an outer ring is integrated in a plastic spherical ball to compensate alignment errors and production tolerances automatically. The corrosion-free 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 varieties with an inner diameter of 10 mm. The diameters 6, 8 and 20 mm are currently being developed.
