Looking for heavy duty solution

We had one set of rollers fail. It lasted only a year. It appears that it started to lose its ball bearings. Is there a heavier duty version of the 81-018 roller? The door is 50" double pain door that is heavy. Or could it be caused by a worn track?

Yes, we have two excellent solutions for you.
First, SWISCO product code 81-149 roller assembly. This patio glass door wheel assembly features both stainless steel housing and stainless steel wheels, good for use in severe weather environments; the weight capacity is 110 lbs per roller. The 81-149 will replace the 81-018 style roller.
Second, we have stainless steel track covers available to snap over existing track. A sliding glass door track cover is an easy way to repair sliding patio door track and will provide a better riding surface for your rollers.
