Dayton 3ZN16 Shaft Arbor Overview

The Dayton 3ZN16 is a heavy-duty Type D machined washer shaft arbor designed for mounting buffing and finishing wheels on electric motors. It fits a 5/8 in shaft diameter and works with Dayton keyless chucks to drive shank-mounted power tool accessories. This new hand tool includes a hex nut and machined washers for secure assembly in automotive and workshop environments.

Sustained Load Behaviour

The heavy-duty construction supports continuous operation when driving buffing wheels at counter-clockwise rotation. Thread length of 2 1/4 in and 1/2 in.-20 RH thread size maintain engagement under torque. Maximum wheel width of 1 5/8 in and washer outside diameter of 1 1/2 in distribute clamping force evenly across the wheel face during extended finishing tasks.

Installation and Common Issues

Installation requires aligning the arbor with the motor shaft and securing via the socket setscrew. The 6 1/4 in overall length provides reach for various motor configurations. Builders who need a different shaft diameter or clockwise rotation cannot use this model. The fixed thread size and wheel width limit compatibility to specific buffing wheel dimensions only.

Questions about this item

Does the 1/2-20 RH thread generate noticeable heat during extended buffing sessions?

The machined washer and hex nut assembly runs true on the 5/8 inch shaft, keeping friction low so the arbor stays cool during all-day finishing work.

Which motor shaft diameter must I already have for this arbor to fit?

It mounts directly on a 5/8 inch diameter shaft with the included hex nut and machined washers.

Will the 1 1/2 inch washer outside diameter clear the flanges on my older Dayton bench grinder?

The 1 1/2 inch OD washers sit inside standard wheel flanges, and the 1 5/8 inch maximum wheel width matches legacy Dayton buffing wheels.
