iglidur HSD350 plain bearings are standard bearings to ISO 3547-1 after press-fit Load [MPa]
®
for shafts with h-tolerance (recommended minimum h9). Diagram 03: Deformation under pressure and temperature
The bearings are designed for press-fit into a housing
machined to a H7 tolerance. After being assembled into a
nominal size housing, in standard cases the inner diameter 0.70
automatically adjusts to the F10 tolerances. For particular 0.60
dimensions the tolerance differs depending on the wall 0.50
thickness (please see product range table). In relation to 0.40
the installation tolerance, the inner diameter changes with Coefficient of friction [µ] 0.30
