Piston Wrist Pin Bushing Set

DNJ Piston Wrist Pin Bushing Set

DNJ® Piston Pin Bushing Sets are designed to support the wrist pin (also known as the gudgeon pin) within the small end of the connecting rod, ensuring smooth pivot motion between the piston and rod assembly. These sets include replacement bushings for all applicable connecting rods in the engine, engineered to precise tolerances for a secure press fit and optimal alignment. They are an essential component in high-load, high-speed internal combustion engines to reduce friction and wear at the pivotal connection point.

DNJ® Piston Pin Bushing Sets are manufactured from high-grade bronze alloys, often with a precise blend of copper, tin, and phosphorous, selected for their superior anti-friction and load-carrying properties. Bronze offers excellent resistance to galling, high heat tolerance, and a low coefficient of friction, making it ideal for repeated high-speed pivoting under extreme pressures. These bushings are machined to strict dimensional specifications and may include oil grooves to support consistent lubrication and prolong component life.

DNJ® Piston Pin Bushing Sets are manufactured to meet or exceed OEM quality standards.

DNJ® also offers related components such as piston sets, pistons with rings, connecting rod bearing sets, crankshaft main bearing sets, and more. With precision engineering and top-tier materials, DNJ® Piston Pin Bushing Sets deliver exceptional performance and long-lasting durability.
