Champion ZNR16 Air Compressor Main Bearing Assembly

The Champion ZNR16 Main Bearing Assembly is the OEM replacement bearing set (cup and cone) for Champion air compressors that use the ZNR16 main bearing, featuring a cup-and-cone design that provides robust crankshaft support in Champion’s R-Series pumps. This assembly replaces a worn or damaged main bearing to restore crankshaft alignment and reduce end play, helping maintain proper lubrication and overall compressor efficiency. Listed as the ZNR16 Bearing Assembly (Cup & Cone) in supplier catalogs, it is sold as a direct replacement component for compatible Champion equipment, including Speedaire/Champion catalogs and Champion repair parts diagrams. Typical applications include Champion R-Series reciprocating air compressors where the repair parts diagram identifies ZNR16 as the main bearing component. As a genuine OEM option, it is designed to meet Champion's original specifications for fitment within the crankcase bearing journal interface used by ZNR16-equipped units.
