An actuator assembly (10) includes a housing (20), a piston rod (22), and an end gland (26). The housing (20) defines a housing bore (44) that extends along a first axis between a first housing end (40) and a second housing end (42). The piston rod (22) is at least partially disposed within the housing bore (44). The piston rod (22) defines a piston bore that extends from a first piston end towards a second piston end along the first axis. The end gland (26) has a first end gland surface (80) that engages the piston rod (22) and a second end gland surface (82) that engages the housing bore. The end gland (26) defines a first gland groove (94) that extends from the first end gland surface (80) towards the second end gland surface (82). The first gland groove (94) is arranged to receive a self-lubricating filler that engages the piston rod (22). A self-lubricating bushing may also be provided to deposit a lubricant into the piston bore.
