About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1260S
The AirTAC SC200X1260S is a double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. Its 200 mm bore and 1260 mm stroke suit long-travel linear actuation where substantial force is required, such as pressing, lifting, or material transfer in heavy industrial lines.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for contactless end-of-stroke or mid-position sensing. The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end help manage deceleration of large inertial loads, while the PT3/4 port thread supplies the necessary flow for the 200 mm bore.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1260S Is Used
Long-Stroke Material Transfer
Pushes or pulls heavy pallets, frames, or structural components across a 1260 mm travel in assembly or welding lines, with sensor feedback confirming end positions.
Industrial Compaction & Pressing
Delivers up to 28274 N at 0.9 MPa for compacting waste, pressing laminates, or forming sheet metal, where the long stroke accommodates deep tooling or large workpieces.
Automated Heavy Lifting
Raises and lowers heavy fixtures or machine guards over a 1260 mm distance, using the built-in magnet and barrel-mounted sensors to signal safe open and closed positions.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1260S the Right Cylinder?
The SC200 bore generates 15708 N push at 0.5 MPa. If your application can work with less force, stepping down to an SC160 bore reduces push to 10053 N at the same pressure, saving space and air consumption. For higher force, the SC250 bore provides 24544 N push at 0.5 MPa.
At 1260 mm stroke, the piston rod is fully extended far from the front bearing. Any side load, even a small one, creates a large bending moment on the 40 mm rod. Always guide the load externally with linear rails or rods, or consider a guided cylinder, to prevent rod bending, bearing wear, and premature seal failure. For replacement, match five points exactly: 200 mm bore, 1260 mm stroke, PT3/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC200X1260S FAQ
At 0.5 MPa, the cylinder produces 15708 N extending and 15080 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force reaches 28274 N. These values assume clean, filtered air at 40 µm and standard operating conditions.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and tie-rod spacing are not interchangeable. It directly replaces another AirTAC SC200 tie-rod cylinder with the same bore, stroke, PT3/4 ports, and magnet option.
