Guide bushings for linear actuators are subject to intense mechanical stress and wear, especially when external radial forces are applied.

Abstract
Guide bushings for linear actuators are subject to intense mechanical stress and wear, especially when external radial forces are applied. Carrying out simplified wear tests on the materials used in these bushings is important in making it possible to estimate how many cycles the actuator can perform before the bushing must be replaced. This paper presents the results of tribological pin-on-disk testing on an anti-friction lining consisting of a porous bronze sinter impregnated and coated with PTFE+Pb. Test specimens were worn with a steel ball, and wear and friction coefficients were determined experimentally with increasing loads and speeds.File | Dimensione | Formato | |
