Dura-Bond Bearing Company: Seven Decades of Engine Rebuilding Excellence

Few names in the engine rebuilding world carry as much weight as Dura-Bond Bearing Company. Founded in the spring of 1947 in a small former woodworking plant in Palo Alto, California, the company was built on a simple but transformative idea: that a solid, seamless “all-round” camshaft bearing would outperform the interlocking designs of the era. That insight proved correct, and Dura-Bond’s design quickly became the industry standard against which all others are measured.

Today, Dura-Bond operates out of an 85,000-square-foot facility in Carson City, Nevada, and holds internationally recognized ISO 9001 and Oliver Wight Class “A” MRP II certifications. The company has grown from its camshaft bearing roots into a comprehensive supplier of aftermarket engine and transmission components, serving professional engine rebuilders, performance shops, and OEM manufacturers worldwide.

A Complete Portfolio of Engine Rebuilding Components

Dura-Bond’s product catalog spans the full spectrum of precision engine components. Their camshaft bearings—available in standard, aluminum overhead, high-performance, and fluoropolymer-coated variants—remain the flagship of the lineup. The high-performance series features proprietary Micro-Babbitt technology and grain-controlled casting processes that deliver more than double the fatigue strength of conventional bearings, a design that has been validated through extensive lab testing and real-world NASCAR racing applications.

Beyond bearings, Dura-Bond entered the valve seat market in 1996 after acquiring a well-respected valve seat manufacturer. Their engine valve seats use patented powder metal technology—with finely dispersed tungsten carbide in a tempered tool steel matrix—to deliver exceptional machinability, heat resistance, and wear performance. These inserts are engineered to handle the thermal and mechanical demands of modern engines running on unleaded gasoline, diesel, propane, and natural gas.

For builders tackling a full engine refresh, Dura-Bond’s engine hardware kits bundle the essential small parts that are so easy to lose during teardown: cam bolts, woodruff keys, seal housing components, cam eccentrics, bypass valves, and more. And where precision alignment is critical, their dowel pins cover a broad range of applications—from cylinder head and bellhousing dowels to crankshaft and transmission dowel pins—across GM, Ford, Mopar, and other platforms.

Why Engine Builders Trust Dura-Bond

Dura-Bond’s reputation is built not just on the quality of individual parts, but on the depth and breadth of their catalog. Engine rebuilders frequently encounter hard-to-find OEM service parts that are discontinued or difficult to source—Dura-Bond has made it a priority to stock and manufacture many of these items at competitive prices. Their transmission bushing line, which includes full-round Babbitt, bronze, coated, and dry-film-lubricated bushings, reflects the same commitment to material science and precision manufacturing that defines their engine products.

Whether you are rebuilding a classic muscle car, a modern truck, a marine engine, or agricultural equipment, Dura-Bond has the engineered replacement parts to do the job right the first time.
