Motor shaft arbor for small fractional horsepower
This Dayton arbor fits a 5/8 in shaft and uses a 1/2 in. -20 LH thread to secure buffing or finishing wheels on electric motors. The machined washer set and hex nut are included so the wheel clamps evenly. A socket setscrew locks the arbor to the shaft for reliable rotation.
Type B machined washer set
The machined washers distribute clamping force across the wheel face while the hex nut provides a positive stop. The socket setscrew engages the motor shaft directly, preventing slippage during clockwise rotation. All hardware ships assembled for immediate mounting.
Replaces worn or missing arbors on bench grinders
When the original arbor threads strip or the washer faces deform, this unit restores true wheel alignment without replacing the motor. The jump is worth it if the shaft diameter matches 5/8 in and the wheel width does not exceed 1 1/4 in.

Questions about this item
What thread size does the 1/2 In. -20 LH arbor use, and what wheel width does it cap?
The arbor uses a 1/2 In. -20 LH thread and supports a maximum wheel width of 1 1/4 in.
What shaft diameter and overall length must the motor and space accommodate?
It fits a 5/8 in shaft diameter and has an overall length of 3 1/2 in.
How is the wheel secured, and which step is often missed?
Tighten the hex nut onto the left-hand thread, then lock the socket setscrew against the shaft flat — skipping the setscrew lets the wheel work loose.
