Mini Polymer Bearings are self-aligning.

Press Release Summary:

Featuring wall thickness of 3 mm, igubal® spherical bearings are light and resilient, do not require lubrication or seal, and adapt to all angular misalignments. Housing and spherical ball liner absorbs vibrations differently than steel, and rotational, swiveling, and oscillating movements of self-supporting shaft take place within spherical cap, which has dampening effect. Bearing housing is made of igumid G, and internal, independently moving spherical ball is made of iglide® L280.

Mini Bearings Are Light and Resilient

igus adds two new mini polymer bearings to its igubal range

EAST PROVIDENCE, R.I. - February 1, 2008- igus® Inc, the industry-leading developer of plastic cable carriers, bearings and continuous-flex cables, offers a highly resilient, self-aligning bearing with a wall thickness of just 3 mm.

The mini plain bearing is part of igus' line of igubal® spherical bearings. It requires minimal installation space and can be supplied immediately ex-stock. The self-aligning bearing is light and compact, requires no lubrication, is simple to install and adapts to all angular misalignments.

The housing and spherical ball liner absorb vibrations differently than steel: the rotational, swiveling and oscillating movements of the self-supporting shaft take place within the spherical cap, which has a dampening effect.

The bearing housing is made of igumid G, an especially robust, reinforced polymer developed by igus. The internal, independently moving spherical ball is made of iglide® L280, which means a minimum coefficient of friction with the shaft.

iglide L280 is a highly wear resistant, long life polymer; suitable for even harsh environments and rough shafts.

igus reports that its high-performance plastic bearings are being used more and more in applications such as machine tools, handling equipment, laboratories and automation equipment. This trend is because the bearings are dry running and therefore maintenance-free. They do not require a seal even in extremely dirty environments, and they are corrosion-resistant in liquids and chemicals without exception.
