8 mm Bore Print-In-Place Flanged Roller Bearing
This two-bolt flange bearing prints as one piece. Six 12 mm double-cone rollers sit trapped in a V-race between the outer ring and a locking inner hub. The hub has an 8.3 mm slip bore for 8 mm rod and an M3 grub-screw collar. The flange is 104 mm long with M4 holes on 80 mm centres. Use it as a pivot or lazy-susan bearing when you don't have a steel bearing to hand. All the running gaps are 0.5 mm, so the part comes off the plate ready to spin.
