Re: Threaded rod through roller bearings

Here's a cross-section of the drive arrangement I'm considering.

The dark gray rod is the axle; potentially a steel, 3/8-16 threaded rod. It runs through two bearings, shown in white near the center, and has a cantilevered sprocket on one end and a wheel on the other. Threaded onto each end is a 1/2" hex coupling nut. The ends of the axle are drilled and tapped to accept left-handed screws which'll hold plates against the wheel and sprocket to prevent them from backing off.

I was looking specifically at Grade B7 threaded rod available from McMaster-Carr -- part no. 98750A068.
