Proform manufactures high-quality sintered bronze and iron bearings
Operating from a 125,000-square-foot manufacturing facility in Punxsutawney, Pennsylvania, Proform combines scale, precision, and powder metal expertise to support high-volume production programs. With more than 70 compaction presses ranging up to 200 tons, we manufacture millions of bronze flange bearings, sleeve bearings, bushings, thrust washers, spacers, and custom powder metal components for OEMs, distributors, and industrial customers across a wide range of markets.
Our expertise in oil-impregnated, self-lubricating bronze bearings provides customers with reliable, low-maintenance solutions designed for long-term performance. Backed by an ISO 9001-certified quality management system, Proform delivers consistent dimensional control and repeatable quality from initial development through full-scale production. Whether your program requires thousands of components or millions, we have the manufacturing capacity and powder metal expertise to support your long-term production needs.
Oil-Impregnated Bushings & Bearings
Proform’s engineering team works closely with customers from concept through production, helping optimize part geometry, material selection, lubrication, and manufacturing processes to improve performance while reducing overall costs. Our powder metallurgy expertise allows us to produce near-net-shape components that minimize material waste and secondary machining while maintaining consistent dimensional accuracy. We manufacture bronze, iron, and custom alloy components engineered to meet application requirements for strength, wear resistance, corrosion resistance, controlled porosity, and long-term performance.
Oil impregnation is a core Proform capability and an important advantage of powder metal bearing technology. The interconnected porosity created during the powder metal process allows lubricating oil to be stored within the component, creating self-lubricating bronze bearings and bushings that can reduce friction, wear, and maintenance requirements. Proform manufactures oil-impregnated bronze sleeve bearings, flange bearings, bushings, thrust washers, and other components for applications where dependable lubrication and long service life are critical. Standard products utilize SAE oil impregnation, with alternative lubricant options available for specific operating conditions and application requirements.
Beyond compacting, sintering, and oil impregnation, Proform offers a complete range of value-added manufacturing services to deliver fully finished, production-ready components. Our capabilities include tooling design, sizing, CNC machining, drilling, tapping, assembly, custom packaging, and quality inspection. By providing comprehensive manufacturing and secondary operations, Proform can simplify the supply chain, reduce lead times, and support customers from initial part design through high-volume production and final delivery.
