SPW Oiles 500 Self-Lubricating Graphite Bronze Thrust Washers - 50 MPa Load Capacity, -40 to +300°C Temperature Range
Maintenance-free self-lubricating bronze graphite thrust washers with embedded solid lubricants. Features 750 MPa tensile strength, 210 HB hardness, and operates without oiling. Ideal for high-load applications in metallurgical, mining, and heavy machinery with maximum load capacity of 50 MPa and temperature range from -40°C to +300°C.
SPW Oiles 500 self-lubricating graphite bronze thrust washers combine copper alloy wear resistance with solid lubricant properties for maintenance-free operation without oiling requirements. These washers are engineered for high-load applications with intermittent or oscillating movements.
Primary material: C86300, CuZn25Al5, SAE430 with embedded graphite
Alternative options: SL4 or PTFE available upon request
- Cost-effective solution with higher crash strength compared to standard bronze graphite bearings
- Solid lubricant transfers to shaft through frictional heat, creating optimal oil-powder lubrication conditions
- Hardness rating twice that of conventional bronze graphite bushings
- Maintenance-free operation with no oiling requirements
Standard fabrications include cylindrical bushings, flanged bushings, thrust washers, and slide plates
Custom designs and specialized materials available according to customer specifications
Widely used in metallurgical continuous casting machines, train supports, steel rolling equipment, mining machinery, gas turbines, and similar heavy-duty applications
