patio door roller assembly

A handy person from ontario says:
Hi, I have a wooden patio door (probably 20-30 yrs old) that needs a new roller assembly. The name "Airlite CMHC 5537" is stamped on the window section. Is this a brand name and model number and if so do you carry replacement parts for it? Thanks, Brent
