Need a professional to help identify replacement rollers needed for sliding glass door

Hello, I am in need of help in properly identifying the correct replacement rollers for the bottom of my sliding glass door. Despite cleaning the old rollers and using break cleaner and a brush etc to clean all the junk out of their metal ball bearings a month or two ago, the door has been back to being hard to slide open again. Cleaning the track and rollers etc only helped for two weeks or so and lubricating the track with silicon spray is now only helping for a day or two so I figure I probably need to replace the rollers at this point unless you have a better suggestion?

Unfortunately, the rollers do not have an part number or brand name etc to make identification easy. Attached are a few pictures showing them from when I had them removed for cleaning several months ago. Pleas advise. Thanks.
