About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500TC
The SC200X500TC is a robust double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a 500 mm stroke well within its 1500 mm standard maximum, this model is built for heavy industrial linear actuation. The 40 mm diameter piston rod and 33 mm adjustable air cushion provide stable, decelerated end-of-stroke performance.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot and self-align in swinging load applications. As a genuine AirTAC tie-rod cylinder, it offers a compact, serviceable design that is shorter than an equivalent ISO 15552 profile, making it suitable for space-constrained heavy-duty machinery.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500TC Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed for large forming, stamping, or die-casting machinery, with the TC mount handling any slight angular misalignment.
Bulk Material Gate Control
Operates heavy diverter gates or discharge doors in mining and aggregate handling, where the 28274 N max force can shift dense, compacted materials.
Large-Scale Welding Fixtures
Positions and clamps heavy weldments in automated robotic welding cells, using the trunnion mount to swing the cylinder clear for part loading and unloading.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500TC the Right Cylinder?
Select the SC200 for applications requiring high force output in the 15708 N range at standard plant pressure. If your force requirement is closer to 10053 N, consider stepping down to the SC160 bore. For strokes over 300 mm, always evaluate the potential for side loading on the 40 mm rod; an external guide or linear bearing system is recommended to prevent rod bending and premature seal wear. To ensure a correct replacement, match five key points: 200 mm bore, 500 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a magnet.

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 SC200X500TC FAQ
At 0.7 MPa operating pressure, the SC200 cylinder generates a theoretical push force of 21991 N. The pull force on the retract stroke is slightly lower at 15080 N due to the area occupied by the 40 mm piston rod.
No. The SC200 is a standard double-acting cylinder and will not hold its position when air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
