High quality hardware products of sliding door are mainly reflected in the design and manufacturing level of pulley system, as well as the matching track design. The bearing used for manufacturing pulley must be multi-layer composite structure bearing, the outermost layer is high-strength wear-resistant nylon bushing, and the nylon surface must be very smooth, without edge protrusion; the inner ball bracket is also a high-strength nylon structure, which reduces friction and enhances the lubrication performance of the bearing; The bearing layers are all steel structures. This design can effectively reduce the noise during the sliding process of the pulley, and make the pulley not need to be cared for, and enjoy light lubrication for at least ten years.
The track matching with the pulley is also very important for the use of sliding door. The track for sliding door generally includes cold rolled steel track and aluminum alloy track. Consumers may think that the rail is stronger and more durable than the aluminum alloy track. The thicker the rail wall, the better. High quality sliding door hardware is reflected in the perfect combination of track and pulley, rather than a simple part.
The track must have a perfect radian to fit the pulley, followed by the material problem. Generally speaking, imported materials should be superior to domestic ones. Consumers should know that it is not difficult for any product to make the same shape, but the difficulty is to look like it and not leave it. Any consumer hopes that the hardware of sliding door purchased by them can be used for a long time without failure. Therefore, high-quality manufacturers of sliding door hardware must also consider the problem of steel plate ratio for rail manufacturing and alloy ratio for aluminum alloy track, so consumers should not pay attention to the thickness of rail unilaterally.
In the choice of rail and aluminum alloy track, consumers should not one-sided think that the rail must be better than the aluminum alloy track. A good track depends on the strength design of the track and the smoothness of the contact surface between the rail and the pulley. A good aluminum alloy track is better than the rail in noise resistance. In addition, consumers should not be confused by the product packaging or the coating on the surface of aluminum alloy. Unreasonable coating can only damage the surface finish of the track. Therefore, do not think that the darker the coating on the rail surface is, the better, it is likely to be just the opposite; and the product packaging only depends on its immediate use effect, and there is no need to bear extra high packaging costs for manufacturers.
