ABSTRACT:
A bearing support arrangement for a grader blade uses short stroke hydraulic cylinders to compensate for wear between slide bearings and slide rails of the grader blade. The cylinders are preferably pressurized by grease and a grease fitting is provided for each cylinder to provide convenient access, to allow service by the operator. Preferably the cylinders are located in a generally closed cavity between the bearing support holder and the slide bearing.
