Table 02: Maximum surface speed

Permissible sliding speeds
The maximum permissible sliding speeds depend on the operating time and the type of movement. A plain bearing is subjected to the highest loads during long-lasting rotating movements. Here, the maximum speed for iglidur® F2 bearings is 0.8 m/s. The values specified in Table 02 can often not be achieved in practice due to interactions.

Temperatures
The ambient temperature has a strong influence on the properties of plain bearings. The compressive strength of iglidur® F2 plain bearings decreases with increasing temperatures. diagram. 02 illustrates this relationship. Additional protection is required at temperatures higher than +70 °C.

Table 06: Moisture absorption of iglidur® F2

Moisture absorption
The moisture absorption of iglidur® F2 bearings is about 0.2 % in a normal climate. The saturation limit in water is 0.4 % and thus very low. This must be taken into account under appropriate operating conditions.

Table 07: Important tolerances for iglidur® F2 plain bearings according to ISO 3547-1 after press-fitting

Installation tolerances
iglidur® F2 bearings are standard bearings for shafts with tolerance (recommended minimum h9). The bearings are designed to be pressed into an H7-toleranced mounting; after installation in a mounting with nominal dimensions, the inner diameter of the bearing is automatically adjusted with E10 tolerance in standard cases. For certain dimensions, the tolerance deviates depending on the wall thickness (see product range).
