How to choose hardware door and window pulley

1. Material: The material of pulley directly affects its service life and performance. High-quality pulleys are usually made of corrosion-resistant, high-strength materials such as stainless steel, aluminum alloy or copper. Avoid plastic pulleys as they are prone to wear and break.

2. Bearing: The bearing type of pulley determines the smoothness of its sliding. High-quality pulleys should use high-quality bearings, such as stainless steel ball bearings or ceramic bearings.

3. Load-bearing capacity: Choose the right pulley according to the weight and size of the doors and Windows. Ensure that the bearing capacity of the pulley is greater than the weight of the doors and Windows to prevent the pulley from being damaged due to excessive pressure.

4. Sealing performance: high-quality pulleys should have good sealing performance to reduce the noise and air leakage caused by doors and Windows during use. Pulley with rubber sealing ring can be selected to improve sealing performance.

6. Installation method: Select the appropriate installation method according to the type and structure of doors and Windows. Common installation methods include single wheel, double wheel and four wheel. Ensure that the pulley is installed in a way that matches the doors and Windows to ensure a good use effect.

7. Appearance and color: Choose pulleys that coordinate with the style and color of the doors and Windows to improve the overall beauty.
