A snubber for a machine is provided. The snubber includes a frame that is mounted on an implement of the machine, a shaft that is operatively coupled to a movable component of the implement and a housing that is coupled to the shaft and rotatably received within the frame. The housing defines a cavity that is configured to store a fluid therein in a sealed manner. The snubber also includes at least one brake disc disposed within the housing and configured to rotate with the shaft and at least one brake pad disposed within the housing and configured to frictionally engage with the at least one brake disc to oppose rotational movement of the housing relative to the frame. The fluid is configured to at least partly remove heat generated due to the frictional engagement between the at least one brake disc and the at least one brake pad.
