Proof load test gauge for swag bearing

Abstract

An improved device for proof load testing of bearings comprising of a cylinder body (8) and a piston (3) which are slidably mounted with a male and female internal coupling design, creating an cylindrical type cavity (9) within the body. The cavity is filled with hydraulic fluid. An axial bore hole (10) extends through the center of the piston and cylinder. A threaded enlongated bolt (1) is extended through the axial bore hole and a bearing assembly and into a threaded recessed receiver die (6). The bolt is tightened, forcing the device against the bearing assembly and the forcing the bearing against the recessed area of the receiver die. The pressure created by tightening the bolt is measured by a hydraulic gauge (12) attached to the cylinder body. When predetermined pressure by the tightened bolt is reached on the hydraulic gauge, a mechanical gauge attached to the receiver die is examined to verify or prove the bearing has withstood the load within manufacturer's specified tolerances.
