Last time I went to my friend s new house, I saw that his balcony kitchen was all made of Rongjun s

1. All the smooth sliding is because the quality of the pulley accessories used is relatively good, as far as I know, the pulley used in the Rongjun sliding door is 304 stainless steel silent pulley, which slides smoothly and is almost silent.

The smooth push and pull is not the role of the aluminum profile, but the role of the roller. Don't look at the roller is just an accessory, but the usual opening and closing of the sliding window depends on it, and the quality requirements are absolutely high.

The sound of the metal wheel rolling is louder, and the sound of the nylon wheel rolling is smaller. I hope my answer can help you.

Pay attention to lubrication, the slide rail and pulley resistance is large, abnormal noise, poor movement, and even wear down the slideway.

Our sliding door factory generally uses professional sliding door wheel rail grease, which is colorless and transparent, with good adhesion and good durability. Tiger head hotolube or Kruber can be used, with food-grade safety certification, suitable for household use. There are 130 grams of tubes in the hedge.

When using, apply directly to the slide rails and pulleys, and open and close the sliding door a few times.

Do not use lubricating oil and regular butter on the slide rails and slides of the sliding doors, as the lubricating oil will be lost quickly. Regular butter will have a harmful smell that is not good for the human body.
