High quality sliding door hardware products are mainly reflected in the design and manufacturing level of its pulley system, as well as the matching track design. The bearing used for pulley manufacturing must be multi-layer composite structure bearing, the outer layer is high-strength wear-resistant nylon bush, and the nylon surface must be very smooth, without arris protrusion; the inner layer ball bracket is also high-strength nylon structure, which reduces friction and enhances the lubrication performance of the bearing; The structural layers of bearing force are all steel structures. This design can effectively reduce the noise during the sliding process of the pulley, and can {todayhot} make the pulley free of care and enjoy light lubrication for at least ten years.
The track matched with pulley is also very important for the use of sliding door. Generally, there are two kinds of tracks for sliding door: cold rolled steel track and aluminum alloy track. Consumers may generally think that the rail is stronger and more durable than aluminum alloy rail, and the thicker the rail is, the better. In fact, it is not always the case. High quality sliding door hardware is embodied in the perfect combination of track and pulley, rather than a single part.
The track must have a perfect arc with the pulley, followed by the material problem. Generally speaking, imported materials should be superior to domestic materials. Consumers should know that it's not difficult for any product to make the same shape. What's difficult is that it looks like it's immortal. Any consumer hopes that the sliding door hardware purchased by him can be used for a long time without failure, so the high-quality sliding door hardware manufacturer must also consider the steel plate ratio for manufacturing rail and the alloy ratio for aluminum alloy rail, so the consumer should not pay one-sided attention to the thickness of rail.
