Patio Door roller

A quick learner from USA says:
HOUSE WAS BUILT IN 1967. ROLLERS ARE GOING BAD FOR THE SECNOD TIME. WAS ABLE TO FIND THEM THE FIRST TIME, BUT NOT NOW. WOULD LIKE TO KNOW IF YOU HAVE ANY ASSEMBLYS , OR JUST THE ROLLERS. THE ROLLERS ARE 1.75 IN DIA. WITH 1/4" HOLE. ON THE ROLLER IT IS PRINTED KILIAN SYRACUSE, NY.

I don't believe we can replace the entire assembly, but see our 81-116 1-3/4" replacement wheel, along with the 81-310 axle. We also have the 81-272 1-1/2" wheel replacement kit. It's 1/4" smaller than your original, but the steel wheel should last longer and you may be able to adjust the roller unit to make up the difference. What do you think?
