About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X15
The AirTAC SC200X15 is a double-acting tie-rod cylinder delivering substantial force in a very short stroke format. With a 200 mm bore, it generates 15708 N of push force at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for compact clamping and pressing operations.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 port connections. The total extended body length is approximately 259 mm, combining the 244 mm body length A with the 15 mm stroke. Its adjustable air cushion (33 mm cushion length) decelerates the piston smoothly at end-of-travel, protecting the end caps from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X15 Is Used
Heavy-Duty Clamping
Short-stroke 200 mm bore cylinder provides high force for secure workpiece clamping in machining and welding fixtures.
Press-Fit Assembly
Delivers up to 28274 N at 0.9 MPa for bearing insertion, bushing press-fit, and component staking operations.
Die Cushion Actuation
Compact 15 mm stroke suits punch press die cushions and stripper plates where space is limited but force demand is high.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X15 the Right Cylinder?
For applications requiring slightly less force, the SC160 bore provides 10053 N at 0.5 MPa, while the SC250 steps up to 24544 N. When replacing an existing cylinder, match five key points: bore (200 mm), stroke (15 mm), port thread (PT), mounting accessory (basic), and magnet option (none). Even with a short 15 mm stroke, ensure the rod is not subjected to lateral loads—external guides are recommended if side forces are present.
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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X15 FAQ
At 0.7 MPa operating pressure, the SC200X15 produces 21991 N of push force and 15080 N of pull force, based on the official AirTAC thrust table for the 200 mm bore.
No. The SC200X15 is a double-acting cylinder and does not hold position when pressure is exhausted or the directional valve is centered. For load holding without live pressure, a pilot-operated check valve or external rod brake is required.
