Abstract
An actuator assembly includes a housing, a piston rod, and an end gland. The housing defines a housing bore that extends along a first axis between a first housing end and a second housing end. The piston rod is at least partially disposed within the housing bore. The piston rod defines a piston bore that extends from a first piston end towards a second piston end along the first axis. The end gland has a first end gland surface that engages the piston rod and a second end gland surface that engages the housing bore. The end gland defines a first gland groove that extends from the first end gland surface towards the second end gland surface. The first gland groove is arranged to receive a self-lubricating filler that engages the piston rod. A self-lubricating bushing may also be provided to deposit a lubricant into the piston bore.
