About the Airtac SC50 Standard Cylinder SC50X163STC
The SC50X163STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) with the TCM1 bracket (F-SC50TC) for pivoting applications. The 163 mm stroke fits compact linear transfer and clamping operations where the cylinder body must swing.

Where the Airtac SC50 Standard Cylinder SC50X163STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on packaging conveyors where space is tight.
Clamping Fixtures
With 1767 N of clamping force at 0.9 MPa, this cylinder secures workpieces in CNC welding jigs, with sensor confirmation via the built-in magnet.
Tilt Mechanism Actuator
The TC mount enables the cylinder to swing as it strokes, perfect for tilting small hoppers or chutes in material handling systems.
Is the Airtac SC50 Standard Cylinder SC50X163STC the Right Cylinder?
For higher force, the 63 mm bore SC63 series offers 1559 N at 0.5 MPa. If a smaller footprint is needed, the 40 mm bore provides 628 N. This TC configuration suits pivoting loads; ensure the trunnion pins are aligned to avoid binding.
To replace an existing cylinder, match five points: 50 mm bore, 163 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S). The SC is a tie-rod cylinder and is not dimensionally interchangeable 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 SC50X163STC FAQ
At 0.5 MPa it produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force reaches 1767 N.
No. Like all standard double-acting cylinders, the SC50X163STC will not hold position when pressure is exhausted. If load holding is required, add a pilot-operated check valve or an external rod lock.
