Table 02: Maximum surface speeds

Permissible surface speeds
Although important solid lubricants were intentionally not used when iglidur® C was developed, the plain bearings are wear-resistant and therefore also suitable for continuous movements at medium surface speeds. Although it is possible to reach short-term speeds of up to 1.5m/s, the main applications should involve speeds of less than 0.5m/s.

Table 03: Temperature limits for iglidur® C

Temperatures
The upper short-term application temperature is +130°C. However, it is not possible to subject the bearings to loads at this temperature. The temperature should therefore be limited to approximately +80 to +90°C. Please note that the bearings must be mechanically secured in the housing at temperatures above +40°C so as to counteract the risk of the bearing becoming detached.

Radioactive radiation
Plain bearings made of iglidur® C are resistant to a radiation intensity of up to 2 x 104Gy. Higher radiation weakens the material and can cause the loss of important mechanical specifications.

Moisture absorption
The moisture absorption of iglidur® C plain bearings amounts to approx. 7% at saturation in water and must therefore be taken into account in applications in humid environments.

Table 07: Important tolerances for iglidur® C plain bearings according to ISO 3547-1 after press-fit

Assembly tolerances
iglidur® C plain bearings are the standard for shafts with h-tolerance (recommended minimum: h9).

The bearings are designed for press-fit into a housing machined to a H7 tolerance. After being assembled into a nominal size housing, the inner diameter automatically adjusts to the D11 tolerances.
