IGUS has extended its 'igubal' range of self-adjusting bearings, made completely from plastic, with the development of two new mini bearings.
Available from Treotham Trading , both are extremely light and compact, simple to install and adapt to all angular deviations.
In the field of bearing technology, machine components made of compounded high-performance polymers are being used more and more often in materials and bulk handling, in laboratories, and in jig construction.
This trend is due to the fact that the material properties allow these bearings to be used for dry applications. They are maintenance-free, manage without a seal - even in heavily soiled environments - and are corrosion-resistant in liquids and chemicals.
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 compared to the model that preceded it (22mm shaft diameter).
The mini plain bearing has a wall thickness of 3mm, 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. This 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.
New mini pedestal bearing
Igus has now developed a new mini pedestal bearing for high radial loads (shaft diameter 8 mm: radial tensile load 1600 N). This self-adjusting bearing also absorbs high forces - but only weights 30% as much as it predecessors.
This sturdy mini version can be supplied in 5, 6, 8 and 10mm sizes. The pedestal bearing is either fixed in place from below with self-cutting Spax screws or with M3 machine bolts.
