Abstract: A linear actuator assembly for providing an axial force. The assembly comprises a torque input assembly, a torque multiplier assembly and a linear actuator. The torque input assembly is driven at an input torque and input speed. The torque multiplier transfers the input torque to the linear actuator with an increased torque from the input torque.

Abstract: A cam thrust assembly that includes at least one rotatable cam plate and at least one roller retaining recess defined in the cam plate. The roller retaining recess has an inner radius and an outer radius and defines a ramp surface having a shallow portion and a deep portion. The cam thrust assembly further includes a tapered roller positioned in the roller retaining recess on the ramp surface for movement along the ramp surface. At least a portion of the ramp surface is curved between the shallow portion and the deep portion in the direction of the roller travel.

Abstract: A thrust bearing assembly comprising a retainer cage and a plurality of rollers positioned in roller retaining pockets spaced about the retainer cage. At least one of the pockets is an angled pocket having a radial axis that is non-parallel relative to a retainer cage centerline passing through the angled pocket.
