About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X150S
The SC200X150S is a large-bore double-acting pneumatic cylinder delivering a substantial push force of 15708 N at 0.5 MPa (28274 N at 0.9 MPa). Its 150 mm stroke is well within the 1500 mm maximum for the 200 mm bore, making it a standard, readily available configuration.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for contactless position sensing. The cylinder uses a 40 mm diameter piston rod with an M36x2 knuckle thread, PT3/4 ports, and operates with filtered air at 0.15-1.0 MPa, featuring an adjustable air cushion for smooth deceleration.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X150S Is Used
Heavy-Duty Clamping
The 15708 N push force at 0.5 MPa securely locks large workpieces in CNC machining centers and welding fixtures, with the built-in magnet enabling clamp confirmation via barrel-mounted sensors.
Pallet Lifting & Stopping
Deploy in end-of-line palletizing stations to lift or stop heavy pallets. The adjustable air cushion absorbs the kinetic energy of the moving load, ensuring a soft, damage-free stop.
Press-Fit Assembly
Provides the controlled, high-force linear motion needed for press-fitting bearings, bushings, or pins in automated assembly cells, with sensor feedback for quality control.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X150S the Right Cylinder?
Select the SC200X150S for high-force clamping, pressing, or lifting where 15708 N at 0.5 MPa is sufficient. If your application requires even greater force, the SC250 bore provides 24544 N at the same pressure. For a lower force class, the SC160 offers 10053 N at 0.5 MPa. Always match the replacement cylinder across five key points: 200 mm bore, 150 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration.
At a 150 mm stroke, the 40 mm rod is well-supported for axial loads. For applications with significant side loading, even at this stroke, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearing and seals from premature wear.
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 SC200X150S FAQ
At 0.7 MPa operating pressure, the SC200X150S generates a theoretical push force of 21991 N. The maximum push force at 0.9 MPa is 28274 N. For precise sizing, always factor in your application's specific friction and load factors.
Yes, the -S suffix in SC200X150S indicates a built-in magnet. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional brackets.
