High quality sliding door hardware products are mainly embodied in the pulley system design and manufacturing level, and orbit design related to it. Used in the manufacture of pulley bearing must be used for multi-layer composite structure bearing, the outermost layer of high strength wear-resistant nylon bushing, and nylon surface must be smooth, not ribbed raised; The inner ball bearing bracket is also high strength nylon structure, reducing the friction, enhance the lubrication performance of bearing; Tolerance of structure layer of steel structure, this design can effectively reduce the noise in the process of pulley sliding, and {TodayHot} make pulley does not need to do, enjoy the light bright lubrication at least ten years.
Of block matching with orbit is important for the use of the sliding doors, sliding doors in the orbit of generally has two kinds of cold-rolled steel rail and aluminum alloy orbit. Consumers in general may think rail orbit of aluminum alloy with sturdy, orbital wall thickness is thicker, the better, do not use up actually like that. High quality sliding door hardware in orbit and the perfect combination of pulleys, rather than just a certain part.
Rail must have and pulley with perfect radian, second is the material problem. Generally speaking, the imported materials should be superior to domestic materials. Consumers should know that it's not difficult to make the same shape to any product, the hard part is apparent and god. Any what consumers want to purchase the sliding door hardware can trouble-free use for a long time, so the high quality of the sliding door hardware manufacturer must also be considered, manufacturing steel ratio of steel plate and aluminium alloy matching problem of the orbit, so consumers should not be one-sided emphasis on thickness of the orbit.
On the choice of steel and aluminum alloy orbit, the consumer should not be one-sided thought must be better than that of aluminum alloy rails, good orbit depends on the strength of the orbit design and orbit and pulley contact surface finish, good aluminum rail is superior to the rail in terms of noise resistance. In addition, consumers should not be the product packaging or on the surface of the aluminum alloy coating, the unreasonable coating can only destroy the surface finish of the orbit, so don't think rail surface finishes the deeper the color, the better, probably just the reverse; And the use effect of product packaging is that it only temporary, don't need to manufacturers to take on extra high packing.
