Loads

The load capacity of the maintenance-free igubal® bearing elements is very high at normal ambient temperatures. igubal® bearing elements absorb high forces and weigh only a fifth of conventional metallic bearing housings. The excellent dampening properties are based on the fact that the plastic material of the two part bearing can absorb vibrations differently than steel.

However, plastic-specific specifications, such as dependence on temperature and behaviour under long-term stress, must be taken into consideration. For this reason, the load-bearing capacity of the rod ends should be tested in individual practical tests, especially with high continuous loads, low load speeds and higher temperatures.
 

Coefficient of sliding friction and speed

One important advantage of igubal® bearing elements is that rapid, rotary movements of a mounted shaft take place directly in the spherical ball portion made of iglidur® W300. The advantage therefore lies in the plastic vs. steel relationship. Polymer produces lower friction and permits high speeds, even in dry operation. Taking the radial loads into account, maximum surface speeds up to 0.5m/s rotating can be attained.

The angular movements of the spherical bearings, on the other hand, take place on the spherical outer diameter of the spherical portion.

The maintenance-free igubal® bearing elements also permit linear movements of the shaft.
