C67300 High Tensile Manganese Bronze Rods
The C67300 High Tensile Manganese Bronze Rods is high in strength alloy with good bearing qualities. The alloy maintains high impact resistance with with good machinability by making it well suited for clutch bearings, shaft bushings, sleeve bearings, thrust bearings, pump parts, drive shafts, bearing pins, wear plates, gears and cams. It also resists squashing out under high loads and extreme wear applications.
Typical Uses :
- Fasteners: Fasteners, Lead Screw Nuts
- Industrial: Gears and Cams, Wear Plates, Bushings, Seal Rings, Idler Pins, Piston Heads, Brearing Pins, Thrust Bearings, Sleeve Bearings, Propeller Shafts, Shaft Bushings, Clutch Bearings, Drive Shafts, Spindles, Pump Parts, Bearings
- Marine: Hardware, Valve Seats
- Other: Connecting Rods
