Window Roller Assemblies

Question

We have a old manufacturing building converted into senior living in 1978 and at the time it was fitted wiht double glazed sliding alumnium windows. Today we have a number of windows that are difficult to operate due to little maintenance on the roller assembly over the years. We are vewry interested in purchasing new window assemblies but we are having difficulty without knowing the indentity of the window manufacturer. The bright aluminum assembly is used on the botom of the slider that can be adjusted to prevent draging on the tracj wiht the phillips screw on the end of the assembly. The smaller steel assembly i was told is used on smaller windows less than 24 inches. Your help in identifying the hardware would be greatly appreciated that we hope could lead to purchasing of wiondow replacement hardware from SWISCO. Thank you Rick C.

The duller looking roller looks to be a part of our 81-012. I believe the wheel used to be nylon but has worn down to the metal bearing. Take a look at the window where that roller came from, there should be more to it as seen in the 81-012 product picture.

The brighter roller is discontinued and no longer available. I wonder if the 81-012 could be substituted. Take a look at the measurements found on the 81-012 product picture and see if this roller could possibly be adapted to work. Let me know if you need any measurements that do not appear on the 81-012 product picture.

By the way, the 81-012 is usually used to replace a sliding glass door roller.
