Hard fast door pulley

The pulley of the hard rapid door is the core load-bearing component for the door body to run along the track. It bears the load of the door body's own weight (usually 500-2000kg) and high-frequency reciprocating motion (with an average daily opening and closing frequency of over 1,000 times). Its performance directly affects the smoothness of the door body's operation, noise level and service life. Compared with ordinary industrial door pulleys, hard rapid door pulleys need to be adapted to a high-speed operating speed of 0.8-2.0m/s, and at the same time withstand dust, temperature differences and vibration shocks in the environment. Therefore, they have higher requirements in terms of material, structure and precision.

Hard rapid door hinges are typical representatives of "small components determining big performance". Their quality directly affects the safety, durability and operational efficiency of the door body. When choosing, it is necessary to match the material and type in combination with the scene requirements (environment, foot traffic, safety standards). If necessary, anti-pinch hinges should be given priority to enhance the overall safety level.
