single roller patio door

Question

The house was built in the 1980s.  I believe brand could be Anderson but door did not have label listing. The only label that led me to this site was PPG, which made glass. The measurements are listed on a few of the pictures.  The roller appears to be single and am looking to replace since the bearings came off when door was removed.

Good morning, the Great Lakes caterpillar roller assembly from your photos has been discontinued for some time now. However, we've had a service person suggest using the 81-279 as a replacement. The adjustment screw is a little higher, but the wheel rolls nicer than the tank treads.
