The AirTAC Airtac SC40 Standard Cylinder SC40X50SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 50mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X50SCB is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from its 40 mm bore. With a 50 mm stroke and a 16 mm diameter piston rod, it provides a compact yet robust linear motion solution for short-travel clamping and positioning tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The rear double clevis mount (CB, accessory F-SC40CB) allows the cylinder body to pivot, accommodating angular misalignment in articulated linkages. Standard PT1/4 ports and TPU seals (-20 to +70 °C) complete the configuration.

The 50 mm stroke and 628 N force at 0.5 MPa make this cylinder ideal for pneumatic clamps and welding fixtures where a short, firm hold is needed. The rear clevis mount allows the body to swing into alignment.
Deploy the SC40X50SCB as a compact part stop on conveyor lines. The built-in magnet lets you add sensors to confirm the gate is fully retracted or extended, integrating seamlessly with PLC control.
The rear double clevis (CB) mount is purpose-built for pivoting linkages on small machinery. The 16 mm rod and adjustable air cushion ensure smooth, controlled motion at the end of each 50 mm stroke.
Choose the SC40 bore when your application requires between 400 and 628 N of force at standard plant air pressure; if you need more force, step up to the SC50 which provides 982 N at 0.5 MPa. The 50 mm stroke is a standard length for this bore, keeping the extended body length compact at approximately 192 mm (A=142 + stroke).
For replacement, match these five points: 40 mm bore, 50 mm stroke, PT1/4 port thread, rear double clevis (CB) mounting, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. These values assume dynamic operation; theoretical static force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. For a direct replacement, you must match an existing SC cylinder with the same 40 mm bore, 50 mm stroke, PT port, rear double clevis mount, and magnet option.
