Abstract: A linear actuator assembly comprises a linear actuator which has a housing and an output shaft, the output shaft defining an actuator axis and being movable along the actuator axis between an extended position and a retracted position. The assembly also comprises a buffer carriage arranged in an active configuration in which it is mounted on either the housing or the output shaft. The buffer carriage has a rotary portion which is rotationally coupled to the output shaft such that rotation of the output shaft about the actuator axis requires corresponding rotation of the rotary portion. The rotary portion is rotationally restrained when the buffer carriage is in the active configuration.

Abstract: The invention relates to a flinger device for preventing the ingress of foreign matter such as dust or grit to the vicinity of a contact surface between a rotary shaft lubricant seal and the shaft. The device is adapted to locate on an end of the shaft and has a radially extending flange portion which fits closely adjacent to a radially extending outer end surface for retaining the seal in contact with the shaft. The device also has an axially extending wall part whose outer circumferential surface locates closely adjacent to an axially extending inner surface of the seal retainer. The surfaces of the flange portion and wall part of the device co-operate to prevent or at least restrict the ingress of foreign matter to the vicinity of the seal/shaft contact surface.
