Minnesota Rubber & Plastics is a specialist in the production of precision Thrust Washers and friction components for powertrain and torque management applications.
Transmissions and torque management systems operate at elevated temperatures with precision components rotating at extremely high speeds. Thrust washers are often critical elements of these systems. They provide mechanical strength while limiting friction and weight.
What are Plastic Thrust Washers?
Thrust washers and other load-bearing components are critical elements for the performance of power transmission systems. They need to withstand extreme temperatures while limiting frictional impact on the overall system. Mechanical strength and dimensional precision are necessary for plastic thrust washers to enhance the performance of these high-speed high-load applications.
Material Science: High Strength + Low Friction
Due to the importance of both strength and friction reduction, material selection is critical for thrust components. High-performance thermoplastics (Bearing-grade PEEK, Torlon, Aurum, etc.) are frequently needed in order for these components to survive the harsh environments within a powertrain system. Our team will evaluate an application’s PV rating (pressure x velocity) and consider both dimensional and manufacturing needs in order to identify the optimal material.
Molding and Manufacturing
High-performance plastics are often more challenging to mold. They require higher molding temperatures and complex tooling strategies in order to optimize repeatability and reduce waste. Our experience with molding these high-performance materials becomes even more critical with complex multi-cavity tools required for high-volume production.
