About the Airtac SC50 Standard Cylinder SC50X30S
The SC50X30S is a compact-stroke double-acting tie-rod cylinder with a 50 mm bore and 30 mm stroke, delivering a push force of 982 N at 0.5 MPa. Its 20 mm diameter piston rod and M16x1.5 knuckle thread provide solid alignment for short-throw clamping and pressing tasks.
A built-in magnet (the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for end-of-stroke detection. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston quietly, and the PT1/4 ports suit standard pneumatic plumbing.

Where the Airtac SC50 Standard Cylinder SC50X30S Is Used
Short-Stroke Clamping
The 30 mm stroke and 982 N push force at 0.5 MPa make this cylinder ideal for compact fixture clamps on CNC machining centres where space is tight and sensor confirmation is required.
Part Stops & Diverters
Use the SC50X30S as a fast-acting stop gate on light-duty conveyors. The built-in magnet lets you add CMSG sensors to verify the gate is fully retracted before releasing the next item.
Press-Fit Assembly
Delivers a controlled 30 mm press stroke for inserting bearings or bushings into housings. The adjustable cushion softens the end-of-stroke impact, protecting the tooling and the part.
Is the Airtac SC50 Standard Cylinder SC50X30S the Right Cylinder?
For applications needing slightly more force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. When selecting a replacement, match five points: 50 mm bore, 30 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic mounting style. 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 SC50X30S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X30S indicates a built-in magnet is fitted to the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
