High quanlity steering spherical roller bearings
The entire basic steering bearing assembly is called a Triple Tree, Triple Clamp, Steering Head, Steering Head Yoke, or Steering Stem. , but not all, loose ball bearings for their steering races. These bearings have upper and lower outer races that are a tight press fit in the frame and a lower inner race that is press fitted to the steering stem. The upper inner race is a loose fit.
Most late model
steering gearbox use either tapered roller bearings or caged ball bearings. Caged ball bearings and tapered roller bearings are lubed the same way and are much easier to handle. Even with the front wheel removed that front end felt like it weighed a thousand pounds! I slid everything together and "Ping" one lousy ball bearing popped out.
