Compressive Strength

With increasing temperatures, the compressive strength of iglide® TX1 plain bearings decreases. At the short-term permitted application temperature of 338°F, the permitted surface pressure is still 14,500 psi. The recommended mximum surface pressure is a mechanical material parameter. No conclusions regarding the tribological properties can be drawn from this. The graph shows the elastic deformation of iglide® TX1 at radial load.

Permissible Surface Speeds

The typical applications for iglide® TX1 plain bearings are high load pivoting motions at comparatively low speeds. However relatively high speeds are still attainable.The speeds shown in the table are threshold values for low bearing loads. They do not provide any indication of the wear resistance under these parameters.

Friction and Wear

Please note that a sliding surface with a rough surface finish will increase the friction. Shafts that are too smooth also increase the coefficient of friction of the bearing. We recommend shaft surface finishes (Ra) of 0.4 to a maximum of 0.7 µm. Furthermore, the coefficient of friction of iglide® TX1 plain bearings largely depends on the speed and load. As the speed increases, the coefficient of friction will quickly increase as well. With increasing load, the coefficient of friction however sinks continuously.

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

Temperatures

iglide® TX1 is a very temperature resistant material. The long-term upper temperature limit of +248 °F permits the broad use in applications typical for the agricultural, utility vehicle or construction equipment sectors. The press-in and press-out forces of iglide® TX1 bearings are extremely high over the entire temperature range. As a result, additional axial securing is generally unnecessary. Although the levels still remain very high, a certain decline can, however, be observed at temperatures above +212 °F. In some cases, axial securing is therefore recommended from this temperature. When considering temperatures, the additional frictional heat in the bearing system must be taken into account.

Installation Tolerancesiglide® TX1 plain bearings are 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.

Shaft MaterialsIn high load applications, we generally recommend the use of hardened shafts. This particularly applies when using iglide® TX1. However, acceptable wear rates are also achieved on soft shafts with heavy-duty pivoting of less than 14,500 psi. The comparison of the wear rate during rotation and pivoting shown in the graph below highlights that the strength of iglide® TX1 lies in heavy-duty pivoting.
