Roller for sliding glass door

Thank you for reaching out to us. I'm afraid we don't sell a match for the roller in your photos. However, I have heard of this complaint before regarding the nylon wheel not holding up. I recommend you check the diameter of the wheel.  It is listed at 1-1/4", but I think it is closer to 1-1/8" and I'm not sure how much clearance you have at the bottom of the door. 

With that said, take a look at the 81-266 roller kit with the 1-1/4" wheel and the 81-223 wheel with the diameter of 1-1/8". If you do go with the 81-223, you will need to order two wheels along with the 81-310 axle kit. Review the specifications for these parts and see what you think.
