Abstract: A hydraulic system includes a pump, a reservoir, and an actuator system. A hydraulic circuit breaker is arranged to compare fluid flow to and from the actuator system and to shut off this flow in the event the flow to the actuator system is greater than the flow returning from the actuator system by more than a predetermined differential, thereby indicating a leakage condition. A hydraulic circuit breaker reset device is hydraulically connected to the actuator system and to the circuit breaker. When the circuit breaker is in a shut-off condition, the reset device continuously pressure tests the actuator system. If the pressure in the actuator system increases to indicate the absence of fluid leakage, the reset device responds to the pressure increase in the actuator system to provide a reset signal to the circuit breaker. After the circuit breaker is reset to its normal operating position, a timing piston returns the reset device to its normal operating condition.

Abstract: A bearing comprising a housing including an outer bearing member having an insert receiving surface and at least one insert sized to be received within the insert receiving surface. A ball and a bearing liner are provided within the housing. Adhesive extruded from the bearing liner during assembly of the bearing is provided between the insert and the insert receiving surface to at least assist in retaining the insert within the insert receiving surface.
