igubal® spherical bearing

The use of spherical bearings is usually associated with the high weight 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 end these disadvantages and open 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.

Here, the spherical ball is made from iglidur® J material, which is known for its low moisture absorption, low coefficient of friction during dry operation and an extremely low tendency to stick-slip. This is especially important for low loads and very slow movements.

Tolerances
Maintenance-free igubal® spherical bearings are designed with a tolerance in the inner diameter according to E10. The shaft tolerance should be between h6 and h9. The bearing clearance can be used to compensate for expansion of the bearing when it heats up.Check the inner diameter


Assembly
igubal® spherical plain bearings are press-fitted into a recommended H7 hole and secured axially. No exact bearing housing alignment is necessary, since the spherical bearing automatically compensates for alignment errors.
