Material and purchase precautions of sliding door pulley

In families, sliding doors can be used in many places, such as kitchens, balconies and bathrooms. Pulley is an important accessory of sliding door. The quality of sliding door pulley will affect the use of sliding door. So what material is of good quality and how to choose to buy sliding door pulley? Let's study together.
1、 Material of sliding door pulley
1. Pure metal wheel
Advantages: bear gravity, wear and deformation.
2. Dry grease
Advantages: The castor surface is made of dry lubricating ester, so it can be easily pushed and pulled, flat, and will not produce friction noise, which makes up for the shortcomings of pure metal wheels.
3. Metal nylon double pulley
Advantages: metal nylon double-closed pulley has the advantages of large stress, pressure resistance, wear resistance and smooth sliding. It is made of pure metal wheels and rubber wheels, and based on the principle of four-wheel dynamic balance and positioning of oil vehicles, without eccentricity and wear. Therefore, many integral wardrobes now use this pulley, which ensures the practicality of the wardrobe and also facilitates people's life.
Many people also install sliding doors in the kitchen and bathroom. If the sliding door pulley is broken, it will make it inconvenient to open and close the door. Whether it is wardrobe door or kitchen door, it will be very troublesome if the sliding door pulley is damaged. If the sliding door pulley device is damaged, it can only be replaced with a new one. We can take down the pulley with a screwdriver. Generally speaking, it will be fixed with screws, so you can remove the whole pulley as long as you remove the screws. Then check the cause of damage. If it is only rusty, apply some lubricating oil, and then install it to see if it can be used flexibly. In this case, we should pay attention to the material selection of the sliding door pulley and try to choose a high-quality sliding door pulley.
2、 Precautions for purchase of sliding door pulley
1. Check the material of the pulley and the sealing condition of the wheel seat.
2. First of all, the material of the pulley should be solid and durable, and then the pulley seat of the pulley should have certain weight resistance and sealing. The wheel seat is generally made of 304 stainless steel composite material with good sealing performance, preventing water vapor from entering the wheel and ensuring the smoothness of the wheel.
3. Look at the compatibility of pulley and aluminum rail. The pulley and rail should be closely matched, and the gap should be small, so that it will not fall off under the impact of external force to avoid safety accidents.
4. It also depends on whether the pulley matches the track. Imported stainless steel and fully enclosed bearing structure are adopted. No matter how many times the door is operated, the service life of decades will not be affected.
5. The pulley and track of sliding door are important, but the pulley should also be maintained during use:
A. When using the movable door, avoid forcing it off.
B. Clean the slideway and pulley regularly and add lubricating oil regularly.
C. Regularly adjust the slider screws to ensure that the slider can effectively load and slide on the movable door.
