A machined washer arbor for mounting buffing and finishing wheels on electric motors with a 5/8 inch shaft

  • Fits 5/8-inch motor shafts for secure wheel mounting
  • Left-hand 1/2-20 thread prevents loosening during clockwise rotation

  • 1-13/16-inch thread length accommodates wheels up to 1-1/4 inches wide
  • Socket setscrew locks arbor firmly to motor shaft

Motor Shaft Arbor for Small Motors

The Dayton 3ZN14 AL-5 arbor mounts buffing and finishing wheels onto electric motors with a 5/8 inch shaft diameter. It suits smaller fractional horsepower motors and rotates clockwise. The overall length measures 3 1/2 inches with a thread length of 1 13/16 inches.

Included Hex Nut and Machined Washers

A hex nut and machined washers are supplied with the arbor so the wheel can be secured immediately. The washers have a 1 1/2 inch outside diameter and the assembly accepts a maximum wheel width of 1 1/4 inches. A socket setscrew locks the arbor to the motor shaft.

For Shops Mounting Wheels on 5/8 Inch Shafts

This arbor fits only shafts of 5/8 inch diameter with a 1/2 inch -20 LH thread, so it will not work on larger motor shafts or different thread patterns. Buyers needing a different shaft size, thread direction or wheel capacity should look at other arbors.

Questions about this item

How often will the machined washers on the 3ZN14 arbor need replacement under normal use?

The machined washers are metal components designed for the life of the arbor; replace them only if they show visible wear, cracking or deformation during routine inspection.

What limits continuous operation when mounting a wheel at the maximum 1 1/4 in width?

The 1 1/4 in maximum wheel width sets the mechanical limit; exceeding it prevents the hex nut from engaging enough thread to clamp the wheel securely.

How much heat builds up on the 5/8 in shaft during all-day buffing?

The arbor itself generates negligible heat; any temperature rise comes from the motor and wheel friction, not from the steel shaft, nut or washers.
