DU/SF-1A Aluminum-Based Self-Lubricating Bushing
The thicker working layer of the aluminum-based self-lubricating bushing allows for post-assembly machining to improve fitting accuracy. The surface working layer offers excellent wear resistance, self-lubricating properties, and functions to dampen vibration and reduce noise, while the aluminum alloy substrate meets lightweight design requirements.
