Brand: Tilton Engineering
This bearing is normally supplied with certain Tilton mechanical throw-out bearings 62-020, 62-021, 62-022, and 62-063 (note that we do not stock any of those bearings). It is also the correct bearing to use on Swift DB-1, DB-2, and DB-3 when running the original Swift HRB setup with a 5.5" Tilton clutch.
The 45.5mm radiused contact face is correct for clutches with a 1 7/8" diaphragm spring hole, including QuarterMaster 5 1/2" and Tilton 7 1/4" (OT-II) or 5 1/2" (OT-III) racing clutches.
The inner race of this bearing has a 40mm bore, designed to be press-fit onto the release piston. The outer race rotates with the clutch. Tilton calls this piston style "Press Fit Type for (Inner Race) Radius-Face Bearings". Note that the TE 60-3000 is the only HRB assembly we currently offer with this piston design.
