Table 02: Maximum surface speed

Permissible sliding speeds
iglidur® A200 has been developed for low sliding speeds. In dry operation, a maximum of 0.8 m/s (rotating) or 2 m/s (linear) is permitted for continuous operation. these specified values indicate the limits at which frictional heat causes the temperature to rise to the permanently permissible temperature. In practice, these limit values cannot always be achieved due to interactions.

Temperatures
The maximum permissible short-term temperature is +170 °C. The compressive strength of iglidur® A200 bearings decreases with increasing temperatures. diagram 02 illustrates this correlation. The temperatures prevailing in the bearing system also have an influence on bearing wear. Additional protection is required at temperatures higher than +50 °C.

Radioactive radiation
Bearings made from iglidur® A200 are resistant to radiation up to a radiation intensity of 1 x 104 Gy. Higher radiation levels attack the material and can lead to the loss of important mechanical specifications.

Table 06: Moisture absorption

The moisture absorption of iglidur® A200 bearings is about 1.5 % in a normal climate. The saturation limit in water is 7.6 %. This must be taken into account under appropriate operating conditions.

Table 07: Important tolerances according to ISO 3547-1 after press-fitting

Installation tolerances
iglidur® A200 plain bearings are standard bearings for shafts with tolerance (recommended at least s h9).
The bearings are designed to be pressed into aH7-toleranced mounting. After installation in a mounting with nominal dimensions, the inner diameter of the bearing with D11 tolerance adjusts itself. For certain dimensions, the tolerance deviates from this depending on the wall thickness (see product range).
