FAQ
Which cup width do I need?
Pick the width that fits your tube, plate or link design. All four cups have the same 2.125" bore and 2.625" OD and take the same bearing, snap ring and spacers. Only the width changes.
What bolt does it take?
The bolt size you choose: 3/4", 5/8", 9/16" or 1/2". The bearing bore is 1", and the two high misalignment spacers step it down to that bolt.
What does 3" stack height mean?
It is the width of the assembled joint: the 1.375" ball plus a .813" spacer on each side, 3" total. Set your mounting tabs 3" apart.
Does the bearing need grease?
No. The Pro 9 bearing has a bonded, self-lubricating PTFE liner, so don't pack it with grease. Grease holds dirt and can shorten liner life.
What does F1 mean?
It is the torque fit. F1 is extremely tight, rated 6 ft-lb to 24 ft-lb no-load breakaway torque.
How does it go together?
Weld the cup in place, ideally with a brass spherical bearing slug in the bore to absorb heat and keep the cup round, and let it cool fully. Press the bearing into the cup, pushing on the outer race only, and seat the snap ring in its groove. Slide a spacer into each side of the ball, flared end facing out toward the mounting tab.
