Tandem roller difference 149 vs. 182

Question

I would like to replace a tandem roller on Lawson impact sliding door. What is the difference between 81-149 and 81-182 other than the diameter of the wheel? Based on the specs the shell is identical, it's just the size of the wheel, please confirm. I have heavy doors and would like to purchase 2 rollers that would last for a few years at least. Should I buy 149 or 182? I do not mind the price difference.
Please advise.

Thank you,
yk

Hello! In addition to the difference wheel size, the wheels on the 81-182 are also ball-bearing. Aside from those two details the two products are identical.

Your next step should be to verify the diameter of the wheel on your door. That will allow you to verify the better match.
