Table 02: Maximum surface speed

Permissible sliding speeds
Although important solid lubricants were deliberately omitted in the development of iglidur® C, the plain bearings are very wear-resistant and are therefore also suitable for continuous movements with medium sliding speeds. short-term speeds of up to 1.5 m/s are possible, but the main applications are at speeds below 0.5 m/s.

Table 03: Temperature limits for iglidur® C

Temperatures
The upper short-term application temperature is +130 °C. However, the bearings can no longer be loaded at this temperature. It therefore makes sense to limit the temperature to around +80 to +90 °C. Please note that the bearing must be mechanically secured in the housing from temperatures of +40 °C to counteract the risk of the bearing coming loose.

Radioactive radiation
Bearings made from iglidur® C are resistant to a radiation intensity of up to 2 x 104 Gy. Higher radiation levels attack the material and can lead to the loss of important mechanical specifications.

Moisture absorption
The moisture absorption of iglidur® C bearings is approx. 7 % when saturated in water and must therefore be taken into account for applications in humid environments.

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

Installation tolerances
iglidur® C bearings are standard bearings for shafts with tolerance (recommended at leasth9).

The bearings are designed for press-fitting into a H7-toleranced mount. After installation in a mounting with nominal dimension, the inner diameter of the bearing with D11 tolerance adjusts itself.
