12PCS 1.8inch Black Silent Garage Door Roller Nylon Door Wheel Replacement Garage Roller, Double Reinforced Cage, Sealed 6200zz Ball Bearing 4 Inch Shaft

💥【What You Get】------- In this kit, you will receive 12 silent garage door rollers. The garage door rollers are 1.8 inches 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%. And the smooth ball bearings effectively reduce rotational friction between the rollers and the shaft, making the garage door open and close quieter and smoother, effectively reducing noise.
💥【Smooth and Strong Sealing】------- Our garage door rollers are equipped with ball bearings that reduce rotational friction between the rollers and the shaft. The professionally sealed bearings can support up to 50 pounds 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 holding the bracket to the door, secure the cable before releasing the lower bracket which is under the tension of the cable spring, clip the cable to the rail, slide out the old roller, place the new roller in position, and screw the bracket back on. 💥【Durable Material】------- 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, a hard, corrosion-resistant material that is stronger than standard bearings. They are manufactured to exceed industry standards and perform 10,000 up-and-down cycles under a 50-pound load.
