Blue anodized arm bearing manufactured by Airlock, designed for the early model A6L and A7L Apollo space suits. The ring measures 5.5″ in diameter and 1.75″ wide, and is engraved on the edge, "Assy 8056, SN-178, A6L-1Z4042-01-MREG." In fine condition. As the suit was being tested for the earlier missions, it was found that these bearings added significantly to the width of the suits when measured across the arms. This made for too tight a fit for the crew as they were strapped inside the Apollo Command Module. To solve this problem, ILC designed their own bearing that was more compact and reduced the width.
