Roll Pin Installation

Postby sdurnal » Tue Sep 17, 2013 6:41 am

Maybe it's "Old Hat" to some of you seasoned veterans, but for those who may not know...

There is a correct way to install roll pins on a rotating shaft. The gap in the pin should always be installed in the direction of rotation, (or opposite) and never according to the center line of the shaft. When a roll pin is installed incorrectly, high torque loads will collapse the roll pin and break it. (then it falls out and the drive fails). Installed in the direction of rotation (or opposite) the pin doesn't collapse.

FWIW Regards,
Stan

Thanks, Stan. Now all I have to do is remember it the next time I install a roll pin. :)
