  • Extra-long 4 1/16 in design reaches recessed wheel hubs

Shaft Arbor for Motor-Mounted Accessories

This extra-long Dayton 3ZN08 arbor fits a 5/8-inch motor shaft and accepts various shank-mounted buffing or finishing wheels. It is designed for counter-clockwise rotation and mounts directly to compatible Dayton keyless chucks on electric motors. The assembly includes a hex nut and machined washers for secure wheel retention.

Installation Steps and Common Issues

Thread the arbor onto the motor shaft using the 1/2-inch-20 RH thread with a 2-5/8-inch engagement length, then tighten the socket setscrew against the shaft flat. The included machined washers and hex nut clamp wheels up to 2 inches wide. Misalignment or insufficient setscrew torque often causes vibration or wheel slippage during use.

Thread Engagement and Wheel Width Limits

The 1/2-inch-20 right-hand thread provides 2-5/8 inches of thread length, limiting maximum shaft penetration and overall stacking height. Wheels wider than 2 inches cannot be clamped by the supplied hardware. Counter-clockwise rotation requirement restricts use to motors wired for that direction only.

Questions about this item

How do I confirm the arbor is seated correctly on the motor shaft after installation?

Verify the 5/8 in shaft diameter fits snugly, the 1/2 in.-20 RH threads engage fully, and the 2 5/8 in thread length allows the hex nut to clamp the 1 1/2 in machined washers against the wheel.

Which components are included with the 3ZN08 and what must I source separately?

The package supplies the extra-long Type C arbor, hex nut, machined washers, and socket setscrew; you must provide the buffing or finishing wheel and a compatible Dayton keyless chuck.

When should I choose this extra-long Type C version over a standard-length arbor?

Select this model when the motor shaft requires the 4 1/16 in overall length and 2 5/8 in thread reach to accommodate wheel widths up to 2 in on counter-clockwise rotating shafts.
