Sliding Glass Door Rollers--Unusual Design

A handy person from Las Vegas, NV says:
I have a house built in the early 60s the sliding glass door has very old bearings with an unusual design. Is there a replacement for this without rebuilding the whole door. Thanks Rod

Thank you for posting, Rod! Take a look at SWISCO part numbers81-016 and 81-017, Capitol Door Rollers. Compare the measurements to see if one of these can work as a replacement.
