High-quality sliding door hardware products are mainly embodied in the design and manufacturing level of pulley system, as well as the supporting track design. The bearings used for manufacturing pulleys must be multi-layer composite structure bearings, the outermost layer of which is high-strength wear-resistant nylon bushing, and the nylon surface must be very smooth, not ridged protrusion; the inner ball bracket is also a high-strength nylon structure, which reduces friction and enhances the lubrication performance of bearings; the structural layer of which is steel. Structures, this design can effectively reduce the noise of the pulley during sliding, and {TodayHot} can make the pulley unnecessary, enjoy light lubrication for at least ten years.

The track matched with the pulley is also very important for the use of sliding doors. There are two kinds of tracks for sliding doors: cold rolled steel track and aluminium alloy track. Consumers may generally think that rails are stronger and more durable than aluminium alloy rails. The thicker the rails, the better. In fact, this is not the case. High quality sliding door hardware is embodied in the perfect combination of track and pulley, rather than a simple part.

The track must have a perfect radian 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, but it's hard to be inseparable. Any consumer hopes that the sliding door hardware purchased by himself can be used for a long time without failures. Therefore, high-quality sliding door hardware manufacturers must also consider the problem of steel plate ratio for rail manufacturing and alloy ratio for aluminium alloy track, so consumers should not unilaterally pay attention to the thickness of the track.

In the choice of rail and aluminium alloy track, consumers should not unilaterally think that rail must be better than aluminium alloy track. A good track depends on the strength design of the track and the smoothness of the contact surface between the track and the pulley. A good aluminium alloy track is better than a rail in noise resistance. In addition, consumers should not be confused by product packaging or aluminium alloy coating, unreasonable coating can only destroy the surface smoothness of track, so do not think that the darker the color of track surface coating is, the better, it is likely to be the opposite; and the packaging of products only depends on its temporary use effect, not for the manufacturer to undertake. Take on extra high packing costs.
