Need Closet Rollers

A quick learner from USA says:
The bottom roller hardware on my sliding glass doors in my front hall closet is broken and needs replacing.

Here are the pictures of the closet door and the rollers. The plastic piece on the roller is broken. All the metal pieces are fine.

The dimensions of the broken piece are:

Diameter 1 1/4" 32mm
Inside Diameter 7/8" 21mm
Width 1/4" 7mm

Let me know what you can find. I need 4 of these as there are 4 rollers and 3 are broken.

Thank you for reaching out to us. We don't sell a replacement for your rollers, unfortunately. If you're able to reuse the housing, I recommend you see if you can just replace the wheels. Take a look at our selection here and see what you think.

81-228 looks like it might work but I need dimensions of width and also the inside diameter of the plastic/nylon piece

Thanks, I still need the inside diameter of the nylon wheel and is it easy to remove the nylon wheel from the overall assembly?

I couldn't locate your exact roller and it's not something I am familiar with so I don't know how easy or difficult it is to remove the nylon wheel. I am sorry we couldn't be of more help in this regard. 

To ensure we get you the right requested measurement, can you outline the portion of the wheel you would like measured on the image below?
