U-shaped nylon PA6 pulley: The pulley is designed with a U-shaped groove and is made of nylon PA6 material. Nylon PA6 has excellent wear resistance, self-lubrication properties, and corrosion resistance, which can effectively extend the service life of the pulley. The U-shaped groove structure can better cooperate with the rope or U-shaped track, preventing the rope from deviating.
Excellent wear resistance: The nylon PA6 material of the pulley has excellent wear resistance, maintaining a good condition over a long period of use and reducing the frequency of maintenance and replacement.
Low noise operation: The operation is extremely quiet, making it suitable for use in places requiring a quiet environment, such as homes and offices.
Easy installation: The installation process is usually simple and can be completed quickly, saving time and labor costs.
Widely applicable: It is suitable for various scenarios such as furniture assembly, industrial equipment, household doors and windows, and drawer tracks, especially performing well in situations requiring rope guidance or linear movement.
Furniture sector: The drawer tracks suitable for furniture such as wardrobes and cabinets, as well as the sliding systems for doors and windows, provide a smooth sliding experience.
Industrial equipment: In some industrial equipment with high requirements for precision and noise, such as automated production lines and conveying equipment, the 687ZZ U-shaped nylon PA6 bearing pulleys can be used for the movement and guidance of components.
Other fields: They can also be applied to curtain tracks, fitness equipment, etc., to meet the sliding needs in different scenarios.
