NTN 612X is a single tapered roller bearing cup made from case carburized steel for long wear life under load. It measures 4.75 in. outside diameter by 1.25 in. width, sized to pair with its matching cone in a tapered roller bearing set. Case carburizing hardens the outer surface while keeping a tougher core underneath, which helps the cup resist pitting and spalling in service. This is a genuine NTN part sold by Pro Gear and Transmission.
