elevator door hanger roller OTIS 140x20x6204 double slot rope synchronous wheel

The main function of the elevator door pulley is to guide and carry the movement of the elevator door, and to roll along the preset track through the groove on its outer wall to achieve smooth opening and closing of the elevator door. The design of the pulley allows the elevator door to remain stable during movement. At the same time, through the cooperation between the pulley and the track, it supports and guides the elevator door, ensuring the stability and safety of the elevator door during the opening and closing process. In addition, the design of the pulley also takes into account the durability and stability of the elevator door under various conditions of use. It is usually made of high-strength metal and has wear-resistant and corrosion-resistant properties to adapt to the humid environment that may exist inside the elevator and extend its service life.

Main functions:

Ensure that the elevator door can move: The door hanging wheel slides through the grooves on the outer wall and the specific track, so that the elevator door can be opened and closed smoothly. The grooves of the door hanging wheel cooperate with the track to play a certain role in the opening and closing of the elevator door.

‌Durability‌: Because the elevator door is opened and closed many times, the door hanging wheel is made of wear-resistant materials.

‌Rust-proof: The door hanging wheel is rust-proofed to ensure its practical life.

Strong load-bearing capacity: The elevator door hanging wheel is made of high-strength metal or cast iron and can support a large weight.
