1.5" roller for sliding door

I have three sliding doors where I want to replace the rollers. They were manufactured in Phoenix by Western Insulated Glass in approximately 1992. They are still in business but say they cannot identify the rollers. Your product 81-175 looks close but the wheels are plastic and I prefer steel.

It's tough to say without knowing your dimensions, but consider our 81-056. Could this be a better match?
