4 Technical Data iglidur Mechanical Properties The recommended maximum surface pressure is a mechanical material parameter. No conclusions regarding the tribological properties can be drawn from this. With increasing temperatures, the compressive strength of iglidur plain bearings decreases. The raph 02 shows this inverse relationship. However, at the longterm maximum temperature of +130 C the permissible surface pressure is almost 40 MPa. Pressure [MPa] raph 02: Recommended maximum surface pressure as a function of temperature (80 MPa at +20 C) raph 03 shows the elastic deformation of iglidur during radial loading. At the recommended maximum surface pressure of 80 MPa the deformation is less than 5 %. The plastic deformation is minimal up to a pressure of approximately 100 MPa. How ever, it is also dependant on the cycle time. Deformation [%] Surface Pressure, page Temperature [ C] Permissible Surface Speeds iglidur has been developed for low to medium surface speeds. The maximum values shown in table 02 can only be achieved at low pressures. At the given speeds, friction can cause a temperature increase to maximum permissible levels. In practice, though, this temperature level is rarely reached. due to varying application conditions. Surface Speed, page 45 m/s Rotating Oscillating Linear Continuous Short term Table 02: Maximum running speed Temperatures Application temperatures greatly affect the properties of plain bearings. The short term maximum temperature is +220 C, this allows the use of iglidur plain bearings in heat treating applications in which the bearings are not subjected to additional loading. The temperature in an application also has an effect on the bearing wear. With increasing temperatures, the wear increases and this effect is signifi cant when temperatures rise over +120 C.

5 iglidur Technical Data Friction and Wear Similar to wear resistance, the coeffi cient of friction µ also changes with the load. The coeffi cient of friction decreases with increasing pressures, whereas an increase in surface speed causes an increase of the coeffi cient of friction. This relationship explains the excellent results of iglidur plain bearings for high loads and low speeds (raphs 04 und 05). Coeffi cient of friction [µ] Coeffi cients of Friction and Surfaces, page 48 Wear Resistance, page raph 04: Coeffi cient of friction as a function of the running speed, p = 0.75 MPa Coeffi cient of friction [µ] Surface speed [m/s] Pressure [MPa] raph 05: Coeffi cient of friction as a function of the pressure, v = 0.01 m/s Shaft Materials The friction and wear are also dependent. to a large degree. on the shaft material. Shafts that are too smooth, increase both the coeffi cient of friction and the wear of the bearing. For iglidur a ground surface with an average roughness Ra = 0.8 µm is recommended (raph 06). raphs 07 to 09 show results of testing different shaft materials with plain bearings made of iglidur. In raph 07 it shows that iglidur can be combined with various shaft materials. The simple shaft materials of free-cutting steel and HR carbon steel have proven best at low loads. This helps to design cost-effective systems, since both iglidur and the shaft are economically priced. It is important to notice that with increasing loads, the recommended hardness of the shaft increases. The soft shafts tend to wear more easily and thus increase the wear of the overall system. If the loads exceed 2 MPa it is important to recognize that the wear rate (the gradient of the curves) clearly decreases with the hard shaft materials. The comparison of rotational movements to oscillating movements shows that iglidur provides advantages in oscillating movements. The wear of the bearing is smaller for equivalent conditions. The higher the load, the greater the difference. If the shaft material you plan on using is not shown in these test results, please contact us.
