  • Counter-clockwise rotation matches compatible motor direction

Dayton 3ZN15 Heavy-Duty Shaft Arbor Type D

The Dayton 3ZN15 is a heavy-duty shaft arbor designed to mount buffing and finishing wheels onto electric motors. It accepts a 1/2 inch shaft diameter and uses a 1/2-20 RH thread with a 2 1/4 inch thread length. The assembly includes a hex nut and machined washers with a 1 1/2 inch outside diameter. Overall length measures 6 1/4 inches and maximum wheel width is 1 5/8 inches.

Shaft Fit and Rotation Constraints

This arbor suits maintenance technicians and machinists who need to drive shank-mounted accessories on a 1/2 inch motor shaft with counter-clockwise rotation. It is not for users whose motors have a different shaft diameter, thread pitch, or clockwise rotation requirement. Builders needing a longer thread engagement or a larger washer diameter should look at other arbors.

1/2-20 RH Thread With Counter-Clockwise Rotation

The single specification that decides compatibility is the 1/2-20 right-hand thread combined with a counter-clockwise shaft rotation requirement. If the motor shaft uses a different thread size, pitch, or rotates clockwise, this arbor will not secure the wheel safely. Verify both the thread and rotation direction before ordering.

Questions about this item

How can I confirm the Dayton 3ZN15 arbor is secured correctly after installation?

Tighten the hex nut against the machined washers until the buffing wheel sits flush with the 1 1/2 in outside diameter washer, then verify the setscrew seats firmly on the motor shaft flat; the arbor should turn counter-clockwise without wobble at full motor speed.

What components come with the 3ZN15 and what must I supply?

The package includes the heavy-duty shaft arbor, hex nut and machined washers; you must provide a Dayton keyless chuck, a 1/2 in motor shaft and the buffing or finishing wheels you intend to mount.

Which version of this arbor suits a 1/2 in shaft with a 2 1/4 in thread length?

The 3ZN15 Type D is the only version listed with a 1/2 in.-20 RH thread, 2 1/4 in thread length and 1 1/2 in washer outside diameter, so select this model when those dimensions match your motor.
