Friction Stay
The multi-layer topological structure stainless steel four-bar can carry 1000N window sash load, and has passed the US AAMA 15,000 cycle wind pressure resistance certification. The patented self-compensating shaft sleeve makes the friction coefficient constant ≤ 0.08, and realizes 1mm-level opening and closing trajectory control in the strong turbulence at an altitude of 280 meters in the Burj Dubai, providing a mechanical fulcrum that never deviates for super high-rise buildings.
