Experimental research on water lubricated three layer sliding bearing with lubrication grooves in the upper part of the bush and its comparison with a rubber bearing

One of the more interesting, currently available water lubricated bearing materials is a three layer composite. Each of its layers has an important function. Specially prepared sliding surface ensures minimum resistance. Following running-in its smoothness becomes very high and the bearing may continue working under fluid lubrication regime. NBR layer ensures bearing elasticity, good vibration damping properties and insusceptibility to shaft axis misalignment. The external brass layer makes fitting the bearing easier. Experiment results of the conducted research were compared with those for a rubber bearing of similar geometry. (C) 2014 Elsevier Ltd. All rights reserved.
