Bottom Roller for Mirrored Closet Door

The roller is locked. The whole roller unit is made of metal - gold colored.

The roller itself is about 1 and 1/8" in diameter.

The door has two rollers at the bottom. One on the left and one on the right. Each roller fits into a bottom track.

Hardware stores in my area carry a similar roller, only the roller is 1.25" in diameter. My roller is 1.125" in diameter. Can I use a 1.25" roller to replace the 1.125"?

The 1/8" difference shouldn't matter unless your door has zero adjustment before it scrapes top or bottom. This would be very unusual for a closet door. The nylon or plastic rollers (23-043) are much more important to keep from wearing down your track with metal wheels.
