Belt drive garage door openers need less lubrication than chain drive but still require some lubrication for optimal performance and longevity, though belt itself does not need lubrication. Belt drive openers like Chamberlain B550, B970, LiftMaster 8355W, and 84505 use rubber-like belt reinforced with steel to move door, belt does not require lubrication and should not be lubricated with grease, as belt is designed to operate dry, lubricating belt can cause slipping and damage. However, other parts of garage door system do need lubrication twice a year, including rollers, hinges, tracks, and torsion springs, use silicone spray lubricant for these parts. Chain drive rail does not apply to belt drive, but trolley and rail may benefit from light silicone spray. Screw drive openers need more lubrication than belt drive. Opener motor and belt drive mechanism are typically maintenance-free and sealed, requiring no internal lubrication. Avoid using heavy grease or WD-40 original formula on belt, as it attracts dust. Use silicone spray on rollers and hinges only. So belt drive garage door openers themselves need minimal lubrication, belt should not be lubricated, but door hardware including rollers, hinges, and springs should be lubricated twice yearly with silicone spray for smooth quiet operation and extended life.
