Roller Bearing Assembly
Delco-Remy

A closely related roller bearing variant provides similar load-support capabilities with a slightly different outer diameter specification, delivering 30.10 mm outer diameter while maintaining the same 30.70 mm width and 22.20 mm inner diameter. This precise difference in outer diameter can align with specific housing bores or mating components within the alternator drive or auxiliary equipment train, ensuring proper fit and minimal play under vibration and temperature changes. Categorized under 77124, these roller bearings support reliable operation of the rotating assembly by preserving correct pre-load and alignment, which translates to steadier voltage output and reduced wear on adjacent races. VMRS 031-001-015 anchors this part within the same bearing family for consistency in replacement practices, while offering a compatible option for fleets seeking exact-match maintenance components to minimize downtime and preserve charging performance across a broad operating envelope.
