Single Roller Sliding Glass Door hardware replacement

We have an older sliding glass door from the late 70s and need to replace the rollers. Could not find any markings on the hardware.
Inside diameter of hardware width = 5/8"
Overall hardware height = 1-3/16"
Roller is approx 1-1/2" and metal with a V-groove to slide along lower rail.
Only one screw holds hardware in place, lower opening on door is for adjustment screw (that currently has no play or movement when adjusted)
