Engineered for applications where traditional lubrication is not feasible, Wrapped Bronze Bearings with Solid Lubricants combine a high-elongation copper alloy with embedded solid lubricants such as graphite. This design ensures smooth, wear-resistant operation, even in environments without oil lubrication, providing long-lasting reliability and reduced maintenance.
High-Elongation Copper Alloy: Thin-wall construction delivers strength, flexibility, and durability.
Embedded Solid Lubricants: Graphite on the bearing surface ensures continuous lubrication without external oil.
Maintenance-Free Operation: Ideal for conditions where regular lubrication is difficult or impossible.
Wear-Resistant: Optimized for long service life under frictional and rotational stress.
