About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X210SH
The SC200X210SH is a large-bore double-acting pneumatic cylinder engineered for heavy industrial actuation. At 0.5 MPa air pressure, it generates 15708 N of push force, scaling up to a powerful 28274 N at the maximum operating pressure of 0.9 MPa. The 210 mm stroke is well within the 1500 mm maximum standard stroke for this 200 mm bore, making it a standard catalog item.
This configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The -H suffix specifies Viton (FKM) seals, which shift the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C, making this cylinder suitable for autoclaves, foundries, or high-temperature process lines. It features a robust 40 mm diameter piston rod with M36x2 threads and PT3/4 ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X210SH Is Used
Sawmill & Log Processing
The 28274 N push force at 0.9 MPa drives log turners, board flippers, and heavy clamping systems. Viton seals handle the high ambient heat from nearby drying kilns.
Heavy Press Feed Systems
Positions steel plate or large castings into stamping presses. The built-in magnet with DMSG sensors provides precise end-of-stroke confirmation to the press controller.
Bulk Material Gate Valves
Operates slide gates for aggregate, grain, or mineral chutes. The high-temperature Viton seals ensure reliable operation even when the cylinder is mounted near hot process ducts.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X210SH the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC series delivers 18095 N at 0.9 MPa, while stepping up to the 250 mm bore provides 44178 N. Always match bore, stroke, PT port thread, and the -S magnet option when replacing an existing unit. The SC200 is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
With a 210 mm stroke on a 40 mm rod, side-loading must be carefully managed. For any non-axial load, use an external linear guide or rod support to prevent bending stress on the rod bearing and premature seal wear. The adjustable pneumatic cushion at each end, with a 33 mm cushion length, decelerates the piston mass smoothly to protect the end caps.
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 SC200X210SH FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. As a standard double-acting cylinder, the SC200X210SH will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load in place without live pressure, you must add an external rod lock or a pilot-operated check valve.
