Compressive StrengthWith increasing temperatures, the compressive strength of iglide® G V0 plain bearings decreases. However, at the longterm maximum temperature of +266 °F the permissible surface pressure is still around 5,076 psi. The recommended maximum surface pressure is a mechanical material parameter.

Friction and Wear

Similar to wear resistance, the coefficient of friction µ also changes with the load. The coefficient of friction decreases considerably with increasing pressures, whereas a slight increase in surface speed causes an increase of the coefficient of friction. This relationship explains the excellent results of iglide® G V0 plain bearings for high loads and low speeds.

➤ Coefficients of friction and surfaces, Page 68 ➤ Wear resistance, Page 69

Temperatures

The ambient temperatures greatly influence the wear performance of plastic bearings. The short term maximum temperature is +410 °F, this allows the use of iglide® G V0 plain bearings in heat treating applications in which the bearings are not subjected to additional loading. The ambient application temperature has a direct impact on bearing wear, an increase in temperature results in an increase in wear. With increasing temperatures, the wear increases and this effect is significant when temperatures rise over +248 °F. At temperatures over +212 °F an additional securing is required.

Installation Tolerances

iglide® G V0 plain bearings are meant to be oversized before being pressfit. After proper installation into a recommended housing bore, the inner diameter adjusts to meet our specified tolerances. Please adhere to the catalog specifications for housing bore and recommended shaft sizes. This will help to ensure optimal performance of iglide® plain bearings.Please contact an iglide® technical expert for support.

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 coefficient of friction and the wear of the bearing. For iglide® G V0 a ground surface with an average roughness between 0.6 and 0.8 µm is recommended. The graph shows results of testing different shaft materials with plain bearings made from iglide® G V0. 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 affect the clearance of the overall system. If the loads exceed 290 psi 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 iglide® G V0 provides advantages in oscillating movements at loads up to 4,351 psi. If the shaft material you plan to use is not contained in this list, please contact us.
