Maximum recommended surface pressure dependent on the temperature: X = temperature [°C]
Y = surface pressure [MPa]

X = Load [MPa]
Y = Wear [μm/km]

Wear of iglidur plain bearings under medium and high loads

Surface pressure

The load of a plain bearing is expressed through the surface pressure (p) in MPa (corresponds to N/mm²). With it the radial load is distributed over the projected surface of the bearing. Radial bearing: p = F/d1 * b1 For axial bearings the load arises accordingly. Axial bearing: p = F/(d2² - d1²) * π/4 Present is

F	Load in N
d1	Inner diameter of the bearing in mm
b1	Bearing length in mm
d2	Outer diameter of the bearing in mm

Maximum recommended surface pressure

A comparative value of the iglidur material is the maximum recommended surface pressure [p] at +20°C. The values of the individual iglidur plain bearings differ greatly on this point. The value [p] indicates the pressure limit of a plain bearing. The plain bearing can carry this pressure permanently without damage. The given value applies to static operation; only very slow speeds up to 0.01m/s are tolerated under this pressure. Higher pressures than those indicated are possible if the duration of the load is short. Please call for further information.

Load and temperature

Diagram 02 and 03 show the maximum recommended surface pressure of the iglidur plain bearing as a function of temperature.

With increasing temperature, this value decreases continuously. Take advantage of the opportunity presented by the predictability of the iglidur plain bearing to record these effects in advance, or determine the effective temperatures in the test.

Load and speed

With decreasing radial load on the plain bearing, the permissible surface speed increases. The product of the pressure [p] and speed [v], the so-called pv value, can be understood as a measurement for the frictional heat of the bearing. This relationship is shown by the pv diagram that is the first in the respective chapter for each iglidur material.

Wear of iglidur plain bearings at low loads

Load and wear

The bearing load influences the bearing wear. The following diagram shows the wear behavior of the iglidur® bearing materials. It is good to keep in mind that for every load there is an ideal bearing.

Load and coefficient of friction

With increasing load, the bearing's coefficient of friction typically reduces. In this connection, shaft material and surfaces are likewise of importance.
