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 bearings used in the manufacture of pulley must be multi-layer composite structure bearings, the outer layer is high strength wear-resistant nylon liner, and the nylon surface must be very smooth, not ribbed; The inner ball bearing bracket is also high strength nylon structure, which reduces friction and enhances the lubrication performance of the bearing. The structural layers of bearing capacity are all steel structures. This design can effectively reduce the noise in the process of pulley sliding, and {TodayHot} can make the pulley not need to be taken care of and enjoy light and smooth lubrication for at least ten years.

The track matching with pulley is also very important for the use of sliding door. Generally, there are two kinds of tracks for sliding door, namely cold-rolled steel track and aluminum alloy track. Consumers may generally think that the rail is stronger and more durable than the aluminum alloy track, the thicker the wall of the track is the better, actually not all. 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, and then the material. Generally speaking, the imported materials should be superior to the domestic materials. Consumers should know that it's not hard for any product to make the same shape. It's hard to look like it's always there. Any consumer hopes the sliding door hardware that he buys can have no malfunctions for a long time to use, so the manufacturer of sliding door hardware of high quality also must consider, the steel plate that makes rail matches a ratio and alloy of aluminium alloy track match a ratio problem, so consumer should not unilaterally pay attention to the thickness of the track.

In the choice of rail and aluminium alloy track, the consumer should not unilaterally think that the rail is better than the aluminium alloy track. Good track depends on the strength design of the track and the smoothness of the contact surface with the pulley in the track. In addition, the consumer should not be confused by the packaging of the product or the coating on the surface of the aluminum alloy, unreasonable coating can only destroy the surface finish of the track, so do not think the color of the surface coating on the track is the deeper the better, probably just the opposite; However, the packaging of the product is only for its temporary use effect, so it does not have to bear the extra high packaging cost for the manufacturer.
