It is very important to purchase the hardware accessories of the electric retractable door correctly

The right to buy electric retractable door hardware accessories is very important to choose the right electric retractable door hardware accessories is very important. General high-quality electric retractable door hardware is mainly reflected in the design and manufacturing level of the pulley system and the matching track design. The bearings used to manufacture the pulleys must be multi-layer composite bearings. The outer layer is a high-strength, wear-resistant nylon bushing. The nylon surface must be very smooth and must not have ribbed projections. The inner ball brackets are also high-strength nylons. The structure reduces friction and enhances the lubrication performance of the bearing; the structural layers bearing the force are all steel structures. This design can effectively reduce the noise in the sliding process of the pulley and can lubricate the pulley.
Everyone knows that the track that is matched with the electric retractable door pulley is also very important for the use of the electric retractable door. The tracks used for the electric retractable door are generally cold-rolled steel rails and aluminum alloy rails. Consumers generally believe that steel tracks are more durable than aluminum alloy tracks, and the thicker the walls of the tracks, the better. In fact, this is a wrong idea, because high-quality electric retractable door hardware is reflected in the perfect combination of track and pulley.
