Motor Shaft Arbor 1/2 in

This Dayton 3ZN12 arbor mounts buffing and finishing wheels onto electric motors with a 1/2 in shaft. The heavy-duty machined-washer design suits smaller fractional-horsepower units in workshop and maintenance settings. A socket setscrew locks the assembly securely to the shaft.

1/2 in-20 LH thread and 1 1/2 in washer OD

The arbor uses a left-hand 1/2 in-20 thread with a 2 1/4 in thread length and includes a hex nut and machined washers. Maximum wheel width is 1 11/16 in and the washer outside diameter is 1 1/2 in. Clockwise shaft rotation is required for the thread to self-tighten during operation.

Hand-tool operation with no power draw

As a passive mechanical component the arbor generates no heat, noise or electrical load. Thermal and acoustic performance depends entirely on the motor and wheel combination selected by the user. Overall length is 6 1/4 in for compact mounting on smaller motors.

Questions about this item

How much thread length does the 1/2 in.-20 LH arbor provide for mounting wheels?

The arbor has a thread length of 2 1/4 in. and a thread size of 1/2 in.-20 LH, giving you that much engagement for securing buffing or finishing wheels.

What does the 1/2 in. shaft diameter and clockwise rotation mean for motor compatibility?

It fits a 1/2 in. motor shaft and is designed for clockwise rotation, so it matches smaller fractional-horsepower motors that turn in that direction.

What is the maximum wheel width the 1 1/2 in. OD washers can accommodate?

The machined washers have a 1 1/2 in. outside diameter and support a maximum wheel width of 1 11/16 in. for secure mounting.
