Replacement wheels for a Del Mar roller

A home owner from San Mateo, CA says:
We have sliding glass doors for closets, that are probably from the mid-1970's or early 1980's.

The wheels have cracked and we'd like to replace then. I pulled out the wheel and housing and took some pictures. This exact Del Mar wheel is not on your web site but there are several that are very close.

It looks like the wheel itself is 1 1/4" diameter (measuring the outside of the wheel). The main housing is 1 3/16" tall and the overall length is 2 1/4(this length does not include the wheel housing).

Photos are attached. Which wheel should we order to replace this?

Thank you,

Thanks for posting, Michael.

Please take a look at our 81-224 Replacement Steel Concave BB Wheel, which matches the measurements for your own. Or the 81-241 for a stainless steel variant.

I was unsure whether we should replace the entire housing or just the wheel itself. Here's the problem - there is a metal piece that curves over the top (see picture) and I think this prevents me from being able to replace just the wheel itself. I have no idea how I take off the wheel - is there an easy way to do so?

Without knowing the width of the roller housing, the closest roller we have is SWISCO product code 81-256. Compare it to your current roller assembly and if the housing is too tall I can continue to research this, just let us know if the widths matched up.
