Great replacement product for aging rollers. Easy to fit, very smooth and quiet operation, plus being sealed definitely will help to keep dust and other particles out. I would recommend these for a terrific upgrade.

The rollers are very well assembled. The bearing is sealed from dirt with a cap/seal. The bearings run true and very smooth. Swapping them out was easy and took all of about 45 minutes. I am waiting on some more parts to complete the garage door rebuild. Once I am done I will return and post an update on the performance and (hopefully) less noise when operating the door.

The nylon roller are made out if good quality material.

Appear to be well made, fit my garage door and do the job they were intended to do.

Like others, my garage door creaked and popped and sounded like it was going to break at anytime. I lubed up the hinges and cleaned the track to no avail. Bought and replaced the old rollers with these new ones and wow, just rolling sounds, no creaks or squeaks. Was impressed with the quality of the rollers compared to the ones I replaced. I believe these will last a long time. The vendor shipped them quicker than expected, and that allowed me to replace the old ones sooner. I would recommend this product and the vendor who supplied them. Be sure to watch a replacement video, it helped me replace them with little drama.
