Contents: 10 Silent Garage Door Rollers. The garage door rollers are 4.6 cm in diameter to ensure ultra-quiet operation, meaning you can enjoy opening and closing your garage door without any annoying noise. They can be matched with most residential garage doors. Ultra-Quiet Operation: The garage door rollers are made of reinforced nylon, which reduces garage door noise by at least 75%. The smooth ball bearings effectively reduce rotational friction between the rollers and the shaft, making the garage door open and close more quietly and smoothly, effectively reducing noise. Smooth and Solid Seal: Our garage door rollers feature ball bearings that reduce rotational friction between the rollers and the shaft. The professional-grade sealed bearings can support up to 22.7 kg on one side, isolating over 99% of dust. In addition, the front and rear sealing caps prevent dust and dirt from entering the rollers. Easy to install: there are two installation methods. First method: slightly bend the track at the seam to remove it, replace the roller, and move the door for the next roller (repeat on the other side). Second method: unscrew the screws that hold the bracket to the door, secure the front cable, release the crank (which is under cable spring tension), clip the cable to the track, slide out the old roller, place the new roller in position, and screw the bracket back on. Durable material: the replacement garage door rollers are made of nylon, which is more durable than plastic and more rust-resistant than metal. The bearings are made of zinc-plated iron, which is hard, corrosion-resistant, and stronger than standard bearings; manufactured to exceed industry standards and perform 10,000 up-and-down cycles under 50 lbs (22.7 kg) loads.
