- Designed for wheels with a 1" arbor opening, so it is not a universal fit for every wheel or shaft setup.
- The adapter is made to be shortened if needed, which adds flexibility but may require fitting before use.
- Shaft flanges are sold as a separate component and are not included with the arbor adapter.
- This is a simple support accessory rather than a performance upgrade for the wheel itself.

Frequently Asked Questions
What does this arbor adapter do?
It converts polishing or grinding wheels with a 1" arbor opening to fit smaller motor shafts.
Is this adapter the same as a shaft flange?
No. The arbor adapter is for fitting the wheel to a smaller shaft, while shaft flanges provide extra side support and a bearing surface for the shaft nut so the wheel can be locked down tight.
What are the listed specifications for the arbor adapter?
The arbor adapter is made of industrial polyresin and is listed at 1" O.D. and 1" long. It may be shortened.
What are the listed specifications for the shaft flanges?
The shaft flanges are plated steel, 2-1/2" O.D., 1" I.D., and 1/8" thick.
Will this fit any shaft size?
The short description says it fits any size shaft, and the long description says the arbor adapters convert 1" arbor opening wheels to fit smaller motor shafts. Exact compatibility depends on the shaft and wheel setup, which is not further specified.
