Igus has expanded its range with the introduction of lubrication-free flange and pedestal bearings with plastic ball bearings.
The Xiros polymer ball bearings with angular compensation have been developed for maintenance-free use in conveyor belts, track rollers and deflection rollers.
The light, corrosion-free and anti-magnetic bearings do not require oil or grease and compensate alignment errors caused by deflection and/or tolerances.
Potential applications include conveyor engineering, automotive parts suppliers, newspaper printers, food and drinks industries, and also textile and glass production and stone processing.
The ball-bearing flange and pedestal bearings are available in two materials.
The first is suited for high-temperatures up to 150C with the inner ring made of Xirodur A500.
The second is aimed at normal temperature environments and is made of 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 bearings are available immediately ex-stock in 16 varieties with an inner diameter of 10mm.
The diameters six, eight and 20 mm are currently being developed.
