<p>The charm of sliding doors lies in sliding, and the quality of hardware accessories directly affects the service life and comfort of sliding doors. The <a href="https://www.lsbarndoorhardware.com/sliding-door-hardware" rel="noopener noreferrer" target="_blank">sliding door hardware</a> mainly includes pulleys, pulley tracks and stop gadgets. High-quality mobile door hardware is mainly reflected in the design and manufacturing level of its pulley system, as well as the supporting track design.</p><p><br></p><p>Three main parts of sliding door: frame, pulley, track</p><p>1. Frame material</p><p>At present, the main frame materials of sliding doors on the market are: carbon steel, aluminum alloy, aluminum-magnesium alloy, titanium-magnesium aluminum alloy and so on. Among them, carbon steel has the lowest price, and titanium-magnesium-aluminum alloy has the highest price.</p><p><br></p><p>The thickness of the frame profile is generally 1.2mm-1.5mm, so that the sliding door can reach a maximum of 2.8 meters, and it will not shake and is relatively stable. If the wall thickness is less than 1.2mm, such as some only 0.8 mm or 1.0 mm, the maximum can only be 2 meters. If it is too high, it will shake and problems will easily occur. The thickness determines the price of the profile, the cost is relatively high, and it also determines the firmness of the sliding door.</p><p><br></p><p>There are roughly two types of profile components: one is aluminum alloy and the other is plastic steel (carbon steel). Because aluminum alloy has the characteristics of light weight and high strength, it is the main material of sliding door base material, and it has gradually replaced plastic steel products. The aluminum alloy itself is divided into ordinary aluminum-magnesium alloy and aluminum-magnesium-titanium-silicon alloy. Aluminum-magnesium-titanium-silicon alloy is an exclusive material in the aerospace field. It has higher strength and smaller weight, and has the advantages of oxidation and corrosion resistance. It is favored by consumers, but the cost is several times that of ordinary aluminum-magnesium alloys.</p><p><br></p><p>2. Pulley</p><p>The most important part of the sliding door is the pulley that carries the weight of the entire door. It is necessary to use high-quality high-strength wear-resistant nylon bushings, and the nylon surface must be very smooth, without prismatic protrusions; the inner ball bracket is also high-strength nylon The structure reduces friction and enhances the lubrication performance of the bearing; the structural layers that bear the force are all steel structures. This design can effectively reduce the noise during the sliding process of the pulley, and can make the pulley need not be cared for, and enjoy light lubrication at least a dozen year.</p><p><br></p><p>A roller is roughly divided into two parts, one part is the bearing and the other part is the outer shell of the bearing. The quality of the bearing plays a key role in the durability of the sliding door. For example, sliding door hanging wheel bearing adopts needle roller bearing, which can maintain the characteristics of precise guidance, high load, smoother, etc., and adapt to the ambient temperature between -20℃ ~ 120℃.</p><p><br></p><p>The twin pulley has the function of wear resistance and noise reduction. There are two pulleys that slide in parallel to further ensure the quietness, smoothness and stability of pushing and pulling. In addition, good pulleys are often designed with two anti-jumping devices to ensure reliable and safe sliding of the cabinet door. Bad pulleys often have only one anti-jumping device or even no anti-jumping device. They are easy to derail during use and difficult to ensure safety. </p><p><br></p><p>3. Orbit</p><p>The pulley guide rail is the core technical part of the sliding door and has to withstand repeated friction, so the guide rail must be strong and wear-resistant. The track matched with the pulley is also essential for the use of sliding doors. There are generally two types of rails for sliding doors: cold rolled steel rails and aluminum alloy rails.</p><p><br></p><p>Consumers generally believe that steel rails are stronger and more durable than aluminum alloy rails. The thicker the rail, the better, but this is not always the case. High-quality sliding door hardware is embodied in the perfect combination of track and pulley, rather than just a component. The track must have an arc that fits perfectly with the pulley, and the second is the problem of material.</p>
