About the Airtac SAI100 Standard Air Cylinder SAI100X75STC
The AirTAC SAI100X75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for short-stroke clamping and high-thrust actuation tasks.
This configuration includes a standard carbon steel piston rod and a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches via the dual sensor grooves on the extruded aluminum barrel. The cylinder uses a PT tapered G1/2 port and features adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI100 Standard Air Cylinder SAI100X75STC Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N push force at 0.5 MPa to execute short-stroke metal forming and stamping operations reliably.
Pallet Diverting
Handles robust diverting of heavy pallets on conveyor lines using the TC trunnion mount to absorb high moment loads.
Parts Ejection
Utilizes the 75 mm stroke and magnetic piston for rapid, position-verified ejection of finished parts from machinery.
Is the Airtac SAI100 Standard Air Cylinder SAI100X75STC the Right Cylinder?
Select this 100 mm bore when 80 mm falls short—the 80 mm variant provides 2513 N at 0.5 MPa, whereas this model yields 3927 N. The 75 mm stroke is optimal for compact, high-force movements. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides should still be used to prevent binding in rigidly coupled setups.
For drop-in replacements, match the 100 mm bore, 75 mm stroke, G1/2 port, and TC trunnion mounting interface per ISO 15552 standards. Remember to include the -S magnet requirement if your control system relies on position sensing. Note that the standard adjustable cushions only decelerate the piston; they do not hold a load. If pressure drops, the rod drifts. Use a SAIL variant or external check valve for position holding.
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 SAI100 Standard Air Cylinder SAI100X75STC FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X75-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in by matching the 100 mm bore, 75 mm stroke, G1/2 port, and TC mounting interface.
