High-Strength 863 Bearing Bronze Rods

- Yield Strength: 62,000 psi
- Hardness: Rockwell B95 (Medium)
- Temper: M07
- Heat Treatable: No
- Specifications Met: ASTM B505
Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated. It is often used for heavy-load bearings, hydraulic cylinder parts, and large valve stems.

Tight-Tolerance High-Strength 863 Bearing Bronze Bars

- Yield Strength: 62,000 psi
- Hardness: Rockwell B95 (Medium)
- Temper: M07
- Heat Treatable: No
- Specifications Met: ASTM B505
Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated. These bars are a higher-strength alternative to tight-tolerance 954 bearing bronze bars. They’re precision ground on the top and bottom for a tight thickness tolerance, saving you the work of machining them.
