The AirTAC Airtac SC50 Standard Cylinder SC50X155S is a genuine double-acting standard air cylinder with a Ø50mm bore and 155mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X155S is a 50 mm bore, 155 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the cylinder barrel for non-contact position sensing. The body length A is 150 mm, making the total extended length approximately 305 mm. Standard PT1/4 ports and TPU seals with a -20 to +70 °C operating range are fitted.

The 155 mm stroke and 982 N push force at 0.5 MPa are well-suited for actuating diverters or gates on light to medium-duty conveyor lines. The built-in magnet provides reliable end-of-stroke sensing for sequencing.
Provides controlled clamping force up to 1767 N at 0.9 MPa for holding parts during welding, gluing, or machining operations. The adjustable cushion ensures a gentle, low-impact contact with the workpiece.
Ideal for pushers and stops in packaging machinery. The 20 mm rod diameter offers good rigidity for the 155 mm extension, and the magnet allows easy integration into automated packing sequences with sensor feedback.
Choose the SC50 bore when your application requires a push force around 982 N at 0.5 MPa. If you need more force, stepping up to the SC63 bore provides 1559 N at the same pressure. For lighter, faster cycling, the SC40 bore offers 628 N. The 155 mm stroke is a standard length and does not require external guides for purely axial loads, but any side force must be managed with an external linear guide to protect the rod bearing.
For a direct replacement, match these five points: 50 mm bore, 155 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code SC50X155S signifies a built-in magnetic piston. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel's sensor groove without any additional brackets.
