About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300STC
The SC200X300STC is a double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa. Its 300 mm stroke is paired with a robust 40 mm diameter piston rod and a 33 mm adjustable air cushion to decelerate high-inertia loads smoothly.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) supplied with the TCM1 bracket for pivoting applications. The body length A is 244 mm, resulting in a total extended length of approximately 544 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300STC Is Used
Heavy Pallet Conveyor Divert
Pushes 15.7 kN at 0.5 MPa to divert fully loaded pallets across a conveyor junction, with the trunnion mount allowing the cylinder to swing as the divert arm moves.
Press Frame Clamping
Applies up to 28.2 kN of clamping force at 0.9 MPa to lock a large forming press platen. The magnetic piston confirms clamp engagement via barrel-mounted sensors.
Dock Leveler Actuation
Pivots a heavy-duty hydraulic dock leveler lip into position. The centre trunnion accommodates the angular movement, and the adjustable cushion absorbs the shock at full extension.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300STC the Right Cylinder?
For a slightly lower force requirement, the 160 mm bore SC160 series provides 10053 N at 0.5 MPa. For maximum force in this tie-rod family, the 250 mm bore SC250 series pushes 24544 N at the same pressure. Always match bore, stroke, PT port thread, centre trunnion mounting (F-SC200TC), and the integrated magnet when replacing.
At a 300 mm stroke with a 40 mm rod, ensure the load is guided externally if any side forces are present. Long unsupported rods are susceptible to bending under offset loads; use a linear guide or rod support 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 SC200X300STC FAQ
At 0.5 MPa (approx. 73 psi), the push force is 15708 N. At 0.7 MPa it rises to 21991 N, and at the maximum operating pressure of 0.9 MPa it reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a standard ISO 15552 profile cylinder, so it is not dimensionally interchangeable. For a direct replacement, match the SC200 bore, 300 mm stroke, PT ports, centre trunnion mount (F-SC200TC), and the -S magnet option.
