This is a solicitation for the manufacture and delivery of Duplex Ball Bearings that must adhere to the military specification MIL-B-17931E for quiet operation. The item is a Qualified Products List (QPL) item, meaning only Government-approved sources will be considered, and qualification for new sources is an extensive, time-consuming process.
