Table 02: Maximum surface speed

Permissible surface speeds
The maximum permitted surface speed is based on the operation period and the type of motion. A plain bearing is subjected to the greatest load during long-lasting rotating movements. Here, the maximum speed for iglidur® F2 plain bearings is 0.8m/s. In practice, the values given in Table 02 are often not reached due to reciprocal effects.

Temperatures
The ambient temperatures strongly influence the specifications of plain bearings. With increasing temperatures, the compressive strength of iglidur® F2 plain bearings decreases. Diagram 02 shows this inverse relationship. At temperatures over +70 °C, additional securing is required.

Table 06: Moisture absorption of iglidur® F2

Moisture absorption
The moisture absorption of iglidur® F2 plain bearings in ambient conditions is approximately 0.2%. The saturation limit in water is 0.4% and therefore very low. This must be taken into account for these types of applications.

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

Installation tolerances
iglidur® F2 plain bearings are standard bearings for shafts with h-tolerance (minimum h9 recommended). The bearings are designed for press-fit into a housing machined to a tolerance of H7. After being assembled into a housing of nominal size, the inner diameter of the bearing automatically adjusts to the E10 tolerance. For particular dimensions the tolerance differs depending on the wall thickness (please see product range).
