Aluminum and glass slider door roller

I'm sorry to say that we don't sell this roller. Being an aluminum door, it's possible that this is just too old for us to supply. Aluminum doors are difficult to repair even in ideal circumstances.

Ordinarily, I'd suggest reusing the housing and swapping out the wheel. But being 2" that's already an extraordinary difference. We don't sell a replacement wheel that large. The largest in our inventory is the 81-237 at 1-11/16" diameter.

I'm very sorry that we can't be of more help.

Thanks for verifying. In that case, see our 81-272 wheel and axle kit. This comes with 1-1/2" diameter wheels and axles used to install them. You will need to drill out the old wheel, then install the original using one of the included axle pairs.

If you'd prefer nylon we do sell the 81-236A, but the axles are sold separately under the  81-310.

Regarding steel and nylon, they both do the job equally well. Where they differ is durability. Steel wheels last longer, but don't fare all that well in salt air environments. On heavier doors they can be unkind to the track, as well. Plastic wheels wear out faster but handle much better on the coast.

We unfortunately don't have a formal guide on that, but it's fairly straightforward. You drill the old wheel out at the axle, then install the new axle using whatever installation method is necessary for the axle type. They all vary. Some just snap together, others need to be hammered in place.

It can be tricky if you've never done such a thing before, though. If you were interested in this process but weren't sure how to approach it, you may want to consider the assistance of a professional. I would rank it an advanced job, but on the low end.
