Table 02: Maximum surface speeds

Permitted surface speeds

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.

Friction and wear

Just like the wear resistance, the coefficient of friction µ also alters with the load (Fig. 04 and 05).

Coefficients of friction µ	0,09 - 0,27	0,09	0,04	0,04

Wear resistance

Shaft materials

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.

Diagrams 06 and 07 display a summary of the results of tests with different shaft materials executed with plain bearings made of iglidur® X. If the shaft material you intend to use is not included in the test results presented here, please contact us.

Installation tolerances

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 )

Chemical resistance

iglidur® X bearings have almost universal chemical resistance. They are usually affected only by concentrated acids.

Radioactive rays

The iglidur® X bearings are radiation resistant up to a radiation intensity of 1 • 10⁵ Gy.

UV-resistant

The excellent material features of the iglidur® X do not alter under UV radiation and other climatic influences.

Vacuum

The iglidur® X bearings can also be used almost unrestrictedly in vacuum. An evaporation takes place only to a minor degree.

Electrical properties

Bearings made of iglidur® X are electrically conductive.
