iglidur® X is designed for higher speeds than other iglidur® bearings. This is made possible by a high temperature resistance and very high thermal conductivity. This is already clear from the pv values of maximum 1.32 MPa · m/s. At the same time, only minimal radial forces act on the bearings in this case. At the specified speeds, an increase in temperature up to the long-term permitted value can occur due to friction.
The friction and wear are also dependent, to a large degree, on the counter partner. Shafts that are too smooth increase the coefficient of friction of the bearing. Ground surfaces with an average surface finish Ra of 0.6 to 0.8µm are ideal.

iglidur® X bearings are standard bearings for shafts with h-tolerance (recommended minimum s h9). The bearings are designed for press-fit in a housing with h7 tolerance. After the installation in a housing with nominal diameter, the inner diameter of the bearing automatically adjusts to the F10 tolerance. In certain dimensions the tolerance in dependence on the wall thickness deviates from this (See delivery program )

iglidur® X bearings have almost universal chemical resistance. They are usually affected only by concentrated acids.
The iglidur® X bearings are radiation resistant up to a radiation intensity of 1 • 105 Gy.
The excellent material features of the iglidur® X do not alter under UV radiation and other climatic influences.
The iglidur® X bearings can also be used almost unrestrictedly in vacuum. An evaporation takes place only to a minor degree.
Bearings made of iglidur® X are electrically conductive.
