💡 How does a sintered bronze oilless sleeve handle dry friction loads?
The handy solid metal matrix acts as an internal reservoir so the bearing runs slick without drip feeds.
- Internal porosity traps trace oils to keep the sliding contact zone lubricated during startup cycles
- Graphite infused compound lowers static resistance when shafts sit idle
- Hardened carbon steel backing absorbs shock without denting under alignment stress
