This assembly is typically used in applications where rotational alignment and load support are critical—commonly within air compressor systems or accessory drive components tied to Cummins-powered equipment. The integrated bushing provides a controlled wear surface, reducing metal-to-metal contact and extending service intervals in high-load environments.
Unlike generic bushings, this is a matched support assembly, meaning tolerances and fitment are designed as a unit—important for maintaining shaft alignment and preventing premature bearing or seal failure.
Often sourced for maintenance on older or military-supported equipment where exact OEM geometry is required and aftermarket substitutions can cause fitment or longevity issues.
Includes only the component shown.
