Deciding Whether Your FANUC Motor Has a Keyway

There are various ways to determine if your FANUC Motor has a keyway:

You can clearly see the holes on the coupling's end when you look at the shaft's end. Your shaft is smooth if it has a single hole in the center of the end. You have a keyed shaft if the shaft has three holes in a row.

Reading the OEM label on the FANUC motor is another technique to determine if you have a keyed shaft without being able to see the shaft directly. One of two different labels, a yellow FANUC sticker or a silver G.E. FANUC sticker, may be attached on your motor. Except for the tag #7000, which shows that it is really a slick shaft, all of the silver G.E. FANUC tags on motors have a # suffix signifying a keyed shaft. The # tag is displayed for each tag in the image below.

How to tell the difference:

• The yellow FANUC label makes identification slightly simpler.
• It is a keyed shaft if the part number bears the # tag at the end of it.
• It is a smooth shaft if there isn't a # at the end of the component number.
• An image of a yellow FANUC tag without the # tag may be seen above.
