Spherical bearings, detectable, EGLM-DT, igubal®
igubal® spherical bearing
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.
Typical applications
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. Exact alignment of the bearing housing is not necessary since the spherical bearing automatically compensates for alignment errors.
