40Cr Alloy Swing Lever

This product is a 40Cr Alloy Swing Lever，widely used in building materials machinery, automated conveying equipment, and precision transmission mechanisms. It is made of 40Cr alloy structural steel, processed via CNC milling, quenching and tempering, and hard chrome plating. The hole position tolerance is strictly controlled within ±0.02mm, with a coaxiality error no greater than 0.02mm, ensuring stable and reliable operation of the transmission mechanism. Quenching and tempering treatment achieves a hardness of 300-350HBS, while hard chrome plating further enhances wear and corrosion resistance, making it suitable for long-term high-intensity working conditions. Sample lead time is 7-10 days, and bulk orders can be delivered within 15-20 days. Customization of different lengths, angles, and hole patterns according to customer drawings is available. #40Cr Alloy Swing Lever #CNC Machined Connecting Link #Mechanical Arm #Custom Building Machinery Component
