About the Airtac SC50 Standard Cylinder SC50X175SH
The SC50X175SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa) from a 50 mm bore. With a 175 mm stroke, this tie-rod design is shorter than an ISO 15552 cylinder, making it a good fit where space is limited. The 20 mm diameter piston rod and PT1/4 ports handle typical industrial air supplies, while the adjustable air cushion at each end decelerates the piston smoothly over 21 mm.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel, eliminating external brackets. The H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C—ideal for hot environments like drying ovens or foundry equipment where standard TPU seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X175SH Is Used
High-Temperature Actuation
With Viton seals rated for 0–150°C, this cylinder is suited for hot presses, autoclaves, or drying lines where standard seals would fail.
Sensor-Controlled Clamping
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position in automated welding or assembly fixtures without external flags.
Material Handling & Sorting
Provides 982 N of push force for diverting or lifting medium-weight packages on conveyor systems, with sensor feedback for precise timing.
Is the Airtac SC50 Standard Cylinder SC50X175SH the Right Cylinder?
Choose the SC50 when your application needs around 980 N of force at standard plant pressure. If you need more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 offers 628 N. For this 175 mm stroke, rod bearing load is moderate, but always align the load axially to avoid side-load bending. To replace an existing cylinder, match five points: 50 mm bore, 175 mm stroke, PT1/4 port thread, the -S magnet option for sensors, and Viton seal material. The SC is a tie-rod cylinder and will not directly interchange with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X175SH FAQ
At 0.5 MPa (5 bar), the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X175SH is a double-acting cylinder and will not hold position when pressure is exhausted or the valve is centered. The piston will drift or drop. For load holding, use a pilot-operated check valve or external rod lock.
