The SC Series Standard Cylinder (Tie-Rod / Big Bore) is a heavy-duty pneumatic cylinder designed for applications requiring high output force, reliable performance, and long service life. Available in bore sizes from 125 mm to 250 mm, it is widely used in industrial automation, material handling, manufacturing equipment, and heavy-duty machinery.
Featuring a robust tie-rod construction, the cylinder provides excellent structural strength and operational stability. The piston adopts a heterogeneous two-way sealing structure with grease retention capability, helping reduce friction and extend service life. Compared with standard ISO cylinders of the same bore size, the SC Series offers a more compact overall design.
The cylinder is equipped with adjustable air cushioning for smooth deceleration and reduced impact at the end of stroke. Multiple mounting options, thread standards (PT, G, NPT), and accessories are available to support various installation requirements. Optional high-temperature seals allow reliable operation in environments up to 150°C.
The SC Series Standard Tie-Rod Big Bore Cylinder is designed for applications requiring high output force, stable operation, and long service life. With larger bore sizes and a rugged tie-rod construction, it is widely used in heavy-duty automation equipment, material handling systems, manufacturing machinery, and industrial production lines.
Compared with standard pneumatic cylinders, the big bore design provides significantly higher thrust output under the same operating pressure, making it suitable for applications involving heavy loads, large workpieces, and long-duty cycles. The compact cylinder structure also helps optimize installation space while maintaining excellent mechanical strength.

The piston adopts a heterogeneous two-way sealing structure designed to improve sealing performance while minimizing friction during operation. This advanced seal design helps reduce internal leakage and maintains stable output force even under frequent cycling conditions.
The integrated grease retention function further enhances lubrication performance, reducing wear on critical sealing surfaces and extending service life. For demanding operating environments, optional heat-resistant sealing materials are available to ensure reliable performance at elevated temperatures.

Large bore cylinders often operate with heavier loads and greater kinetic energy. To ensure smooth motion control, the SC Series Big Bore Cylinder is equipped with an adjustable air cushioning system that reduces impact at the end of each stroke.
The cushioning effect can be adjusted according to load conditions and operating speed, helping to minimize vibration, protect connected equipment, and improve overall system durability. This feature is particularly beneficial for high-force applications where stable deceleration is critical.
