SD Series 77mm Mega-Bore Short Body Open-Center Hydraulic Cylinder

Application:

The Samchully SD Series hydraulic cylinders are designed for high-speed CNC lathes and precision turning centers where compact, rear-mounted actuation is required. Engineered for reliability and efficiency, these short-body cylinders provide smooth, powerful actuation in limited spaces, making them ideal for both standard and high-speed spindle applications.

Product Features:

The Samchully SD-18577CU features a compact, short-body design that maximizes space efficiency without compromising clamping power. Built for high-speed performance up to 5000 RPM, each cylinder delivers powerful and consistent hydraulic force, with 89kN push and 82kN pull capacity ensuring reliable chuck operation. Its precision-machined 77mm bore and 29mm piston stroke provide smooth, repeatable motion, while the robust construction withstands operating pressures up to 4.5 kgf/cm² for long-term durability. The unit includes an M85 × 2.0 drawtube connection with an integrated coolant collector for added convenience and protection, and a low total leakage rate of just 3.0cc ensures efficient and dependable performance in continuous operation.
