Caterpillar 0964277 Carrier Roller Assembly

The 0964277 carrier roller assembly is engineered for Caterpillar hydraulic excavators including the E200B, EL200B, 320C, 322, and 315 series. This top roller supports the track chain, maintains proper track tension, and prevents sag during operation. It utilizes a sealed and lubricated bearing design to exclude contaminants and extend service life in abrasive undercarriage environments. Constructed from high-strength cast or forged steel with a hardened running surface, the roller withstands high radial loads and impact forces typical in construction and earthmoving applications. The shaft diameter measures 1.85 inches (47 mm). Direct replacement for Caterpillar OEM part numbers 096-4277, 0964277, and superseded reference 8E5600. Compatible with machines powered by Caterpillar 3116 and Mitsubishi S6KT engines.
