How long do sealed garage door rollers usually last with 2 door openings/closings per day and how do you know when it's time to replace them?

The nylon rollers with ball bearings should last forever with that light usage (twice a day). The only caution I would make to owners living in a salty, coastal environment: The sellers never mention what metals are used for the ball bearings. If stainless steel is used, no worries. If the bearings are mild steel, I would consider a yearly spray of anti-corrosive lubricant as a precaution. Maybe they are pre-lubed for lifetime, but hard to know. As far as knowing when to replace them: They should be quiet and rotate freely by hand, without binding. These rollers made our door operation so much quieter. I wish I had changed them sooner. The friendly, honest installer who upgraded our Liftmaster opener has to charge $9.00 for each roller (his boss' idea, not his). He's the person that suggested the Amazon search that led to this product. Between the belt-drive Liftmaster and the new nylon rollers, our door is nearly silent.

Don' know but my steel rollers without ball bearings lasted for 12 years and had become noisy but not worn out. I expect my nylon rollers with bearings to last much longer. They are much quieter.

I dont know how Long they are. But it's worth it. I have many rolls and I know they will last for more than a year. I use them once per week.

Yea you can always just put the vacuum back on it. I'd say 1-2 months until it starts really expanding. But I honestly think these bags are garbage unless I got defective ones. They should stay sealed much longer in my opinion

My best guess is that the vinyl wrapping material will last about 6 months before stretching out making a larger roll than original. I've used my current one since May of this year. It seems to be outlasting another one by a different mfr which is already stretched out of shape after only a month. The print is wearing off somewhat; but, that is to be expected. It is still working, ad for the price I am happy with it.

All it takes is the right length of chain. The real key is having good quality rollers. If your gate does not move easily with out an opener them your opener won't last as long. The rollers I'm using we're more expensive but well worth it

I couldn't find a expiration date on mine but I freeze the rolls until I need them and then keep the open end covered and in the fridge. You can call them at 1-800-775-3849, or look for their Facebook page, and get all of your questions answered.

When my garage door started involuntarily closing when I was opening it (with nothing blocking it), I used this stuff to grease the tracks of my garage door. It solved the problem. I was about to call someone in, so this saved me time and money. With the grease, the door is less rickety when it opens, which I think was what was causing it to start closing. Hope this helps/

The Rollers make all the difference. If your gate rolls well by hand the unit will last. don't use gooey lubricants on the chain. they gum it up and will limit the life of the motor.

We recommend allowing 20 seconds between seals. Under heavy usage the vacuum sealer will shut off automatically and the red light will flash. In this case, you will need to wait 20 minutes for the appliance to cool down before continuing to vacuum and seal.

Just purchased them in January 2014, still very very pleased with these Nylon Garage Door rollers. Did replace a couple of hinges that were worn, from Home Depot. I made sure the pins holding the hinges rotated smoothly and close fit. Look at the picture of National Hardware V7610 7-3/8" High Hinge #3 W/Carriage Bolt & Nuts in Galvanized, very well assembled. Also cleaned all oil and grease from tracks, these rollers are quiet. Practice all safety, wear heavy gloves, garage doors can be dangerous.

genie ga rage door openers are junk. I keep setting my limits and my garage door leaves a crack at the bottom. when the weather gets better im going to buy a chamberlain. Its too bad because they used to be the best. Its like everything else they have been sold twice and are now owned by a foreign company.

I needed to replace both. The rubber seal on the door has to be flexable to make a seal with the threshold on the garage door. Replace both.

Around 40 hours is all I would use it. You should be able to tell when to replace. I keep mine in the bag and sealed when not in use.

I use two in my garage door opening. I set them in a slight zig-zag patern and connect the to the door rails with zip ties. This is a reliable and rugged brand. My dog is 12lbs.

I do not see a way to do that, you could ask the manufacturer, these rollers are indeed awesome, very high quality and make the garage door move easier and much more quietly, it was a great investment at modest cost

It has been my experience the roller does not need replacing just cleaned properly. Good luck!
