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. A roller wheel connected to a roller shaft being a portion of a hinge affixed to a garage door, the roller wheel adapted to roll within a track of a garage door, the roller wheel including at least one ball bearing and a collar retained in a circumferential cylindrical middle cover seal and the circumferential cylindrical middle cover seal covered with a steel cover, the steel cover covered with 50-90 durometer soft urethane plastic.
