The use of spherical bearings is usually associated with high weights of the bearings, difficult installation and high costs. In most cases, however, maintenance is required in the longer term and the bearings are only corrosion-free in special designs. Often roller bearings or plain bearings malfunction prematurely due to high edge loads, or because they need to be readjusted, reamed, or refitted in order to compensate for alignment errors. igubal® spherical bearings ends these disadvantages and opens up new possibilities through their design: They are easy to handle, cost-effective, very lightweight and very robust.
The housing is made of igumid® G, a particularly impact-resistant, long-fibre reinforced polymer. Suitable for temperatures from -30°C to +80°C in long-term use.
In standard spherical bearings, the spherical ball is made from iglidur® W300, a material known for low coefficient of friction in dry running operations and has an extremely low tendency to stick-slip. This is especially important for low loads and very slow movements.
