Abstract:
A roller with a Delrin plastic injection to coat the steel shaft wherein the plastic coated shaft eliminates the metal-to-metal contact that creates the noise. The new and improved Delrin plastic coated shaft will be 1 mm larger than industry standard shafts because 10-11 mm industry standard shafts are too loose in the hinge barrels which allows the rattling. This improved roller shaft is 12 mm at finished thickness to reduce the extra space. Closing the gap between the roller shaft and hinge barrel will eliminate the metal-to-metal contact resulting in a very quiet, rolling garage door. By keeping the finished thickness at 12 mm on the new shaft, the roller will still work on new and old garage door hinges and fixtures. This makes the new and improved roller shaft a truly universal product that will work on 90% of garage doors in service and almost all new models. This is a long over-due improvement to garage door rollers.
