Ultra-Life Max 2 in. Sealed Nylon Garage Door Roller with 7 in. Stem (10-Pack)

These have a 7-inch stem and are designed so you can install a second hinge on your door. The wording in the description is: • Hurricane-rated: the 7 in. stem permits support from 2 hinges to increase durability during a high-wind hurricane or other severe weather That would make them extremely strong against the wind. I have a chain driven opener so it’s not very quiet to begin with, but I noticed an improvement once I replaced the original metal rollers with the new nylon rollers. In searching how to replace the rollers, most videos showed someone bending the track and then popping the rollers out one by one to replace them. Instead I used an impact driver to remove all the hinges. Each only had 3 short bolts and the job was quick. These rollers will last the lifetime of the garage door.

More than I needed but worth the cost for a lifetime of performance. Model # DLMR6200ZZ7 Internet #306315835 DURA-LIFT Ultra-Life Max 2 in. Sealed Nylon Garage Door Roller with 7 in. Stem (10-Pack)in. Stem (10-Pack) My old doors were dragging and hard to open and close. The reason is that over time dirt and other debris build up in the single bearing and causes friction and wear. At first I thought it would a big job but this is perfect a DIY garage door project. It took me about 2-3 minutes per roller and I did not have to remove the door just the roller bracket. See photos. My door had 5 roller per side so I was finished in under 30 minutes. Just install it and forget it.

Another is that it has a dual cage bearings instead of just one, so it rolls easier. The nylon roller is quieter than the old metal roller I had.

Great Rollers! Gave our old garage door a tune up with these sealed bearing rollers. Super quiet with nice action compared to the old steel rollers. Swapping out the old for the new took about an hour from the time I pulled the cars out, gathered tools, disengaged the garage door opener, swapped them, cleaned up and put the cars back in. A simple, inexpensive upgrade to quiet your garage door and reduce wear on your opener. Ironically, I'm expecting these rollers to last longer than the door itself!

Awesome rollers! With the sealed bearing, I won’t have to worry about cleaning and grime build up, or, changing out my rollers anytime soon. BONUS the nylon wheels are completely quiet compared to the CLANG and BANG of my old metal wheels. It took me about 5 minutes to change them out and only needed a long screwdriver to pop the old ones out and a rubber mallet to pop the new ones in!! LOVE THEM!!

Major differences between my original garage door roller. The sealed bearing makes a big difference with noise and performance. My garage was not noisy but this new set of rollers made it even more quiet. The shaft are long but it did not affect the installation or operation and even added additional feature to add additional brackets. No need to grease the roller less mess and cleaner garage door.

Working good, easy to install, waiting to see how durable they are

Excellent product. I swapped out my original garage door wheels in about 30 minutes with the Dura-Lift wheels. The door rides up and down much smoother and very much quieter now. Very pleased with DuraLift.

These rollers arrived swiftly and were simple to install. No more squeaky garage door!

Great rollers, easy to install, very quiet in operation, good quality and a good price.

So far they seem to be working fine. Did not reduce the noise level as some reviewers advertised
