High-Temperature Dry-Running Sleeve Bearings
Graphite provides a layer of dry lubrication that operates in high-temperature environments.
Graphalloy bearings perform at extreme temperatures and under water. They are electrically conductive and wear resistant.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.
