Replacement garage door rollers for home use. Perfect for replacing old, worn, noisy, or broken rollers. Garage door rollers are easy to replace yourself. Premium nylon and steel wheels with 10 ball-bearings. Standard wheels are made of solid nylon and wear out, but steel wheels can be noisier. Our premium wheels have nylon shells for the quietest possible operation, and steel cores for durability. Each roller contains ten ball bearings for smooth operation. For smooth and easy opening and closing, and to extend the life of the electric door opener, change all rollers at the same time or when adding a new electric opener. Always work carefully and secure the door before starting your replacement.
