Igus has extended its igubal range of self-adjusting bearings made completely from plastic, with the development of two new mini bearings.
The two new mini bearings are light and compact, simple to install and adapt to all angular deviations.
With the new plain bearing KGLM Mini, igus has developed a highly resilient plastic bush, the wall thickness of which has been reduced by half, as compared to the model that preceded it (22 mm shaft diameter).
The mini plain bearing has a wall thickness of 3 mm, requires even less room and can be supplied immediately ex-stock. Due to its two-part structure (housing, ball-type spherical cap), the plastic plain bearing absorbs vibrations differently to steel.
The movements (rotating, swivelling, oscillating) of the self-supporting shaft take place within the spherical cap, which has a deadening effect.
The housing is made of igumid G, a particularly robust, reinforced polymer, and the self-adjusting housing corrects angular faults. An internal, freely moving, ball-type spherical cap ensures compensation of misalignment inaccuracies. The spherical cap is made of iglidur W 300, a material which achieves minimum frictional coefficients between the shaft and spherical cap.
Also, igus has developed a new mini pedestal bearing for high radial loads (shaft diameter 8 mm: radial tensile load 1600 N). The self-adjusting bearing also absorbs high forces – but only weights 30% as much as it predecessors. The sturdy mini version can be supplied in 5, 6, 8 and 10 mm sizes. The pedestal bearing is either fixed in place from below with self-cutting Spax screws or with M3 machine bolts.
