Should sealed bearing locking collars be tightened in the direction of the shaft rotation or opposite the direction of the shaft rotation?

The shaft drives the collar thru the set screw, which in turn tightens on the eccentric of the bearing race.

Always tighten in the direction of rotation to ensure the collar is tight on the eccentric. One light tap is sufficient because the collar will self tighten on on the bearing race. Too much force will crack the bearing race and cause a loose bearing which in turn will cause a worn shaft.

So far the vote is 50-50, but every book I've ever seen, along with one of my co-workers (the other one says opposite), you always tighten in the direction of rotation. If nothing else- always do it the same way, so that if YOU have to dismantle, you know which way to punch it! If it's torch time- it doesn't matter.

Tighten dead shaft collars in the direction of bearing rotation so if set screw comes loose it will self tighten.

Tighten live shaft collars in the opposite direction of shaft rotation so if set screw loosens it will will self tighten.

Service manual for IH 80 3 point snowblower says to tighten them opposite shaft rotation to help ensure they stay tight in the event a set screw loosens.
