Tips for installing sliding hanger door roller


1. First install the hand crank and find the special expansion screw for the hand crank


2. Take out the hand crank, loosen the finger screw on the hand crank, and remove the bottom plate of the hand crank


3. Draw a line against the wall. The general theoretical size is 80 to 100 cm. The actual size can be determined according to the height of each person, that is, the height of the hand crank is installed at the waist, so it is the most convenient to use. Please remember to draw the line When installing, the direction of the bottom plate must be with the arrow pointing up.


4. Use an electric impact drill to mark the place, put in the special screws for the hand crank


5. Align the card slot with the hand crank and rotate it to the left, and use a screwdriver to tighten the finger screws.


The structure of wheel sliding door roller


The sliding door pulley structure is mainly composed of the lower pulley, the upper pulley, the fixing screw, and the lower pulley traction screw.


The upper pulley plays a guiding role. Because it is installed in the upper track, consumers often do not pay attention to it when purchasing. This gives some businesses an opportunity to take advantage of the opportunity to replace only small wheels with rubber rings to make the upper pulley The gap between the upper rail and the upper rail is large, resulting in greater shaking and noise during sliding. The structure of a good upper pulley is relatively complicated. It not only has a bearing inside, but also has aluminum fasten the two wheels to make it slide smoothly and achieve the effect of silence.


About the quality of the bottom roller wheel


Good bottom wheels are generally made of carbon glass fiber, with balls inside, with non-dry grease, and use twin bottom wheels to improve stability and load-bearing capacity. Inferior pulleys are often made of organic plastics, which can slide smoothly through lubricating oil. Therefore, the bearing capacity and wear resistance are not up to standard. The pulley bearing is made of stainless steel, the bearing is installed tightly, and it feels soft and no noise when sliding. Some pulleys can also adjust the height to compensate for the distance between the doors and windows and the track, so that the doors and windows and the track are more closely connected.


Important: Sliding doors should not be as slippery and light as possible when sliding. High-quality sliding doors should have a certain amount of self-weight when sliding, smooth and without vibration.
