About the Airtac SAI63 Standard Cylinder SAI63X600STC
The AirTAC SAI63X600-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. Featuring a 63 mm bore and a 600 mm stroke, this extruded aluminum barrel design provides a robust yet lightweight solution for extended travel requirements.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for seamless integration with CMSE and DMSE reed switches via the dual sensor grooves on the barrel. It utilizes a PT tapered G3/8 port thread and adjustable air cushions at both ends to manage kinetic energy effectively.

Where the Airtac SAI63 Standard Cylinder SAI63X600STC Is Used
Material Transfer
Pushes heavy pallets along extended conveyor lines where the 1559 N force and 600 mm travel distance easily handle automated routing.
Vertical Lifting
Elevates totes or containers in packaging cells, relying on the integrated magnet and CMSE sensors to confirm upper and lower positions.
Long-Reach Ejection
Clears finished machined parts from large press beds, utilizing the adjustable end cushions to decelerate the rod smoothly over the long stroke.
Is the Airtac SAI63 Standard Cylinder SAI63X600STC the Right Cylinder?
Selecting this 63 mm bore over a smaller 50 mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, while stepping up to an 80 mm bore would yield 2513 N. The 600 mm stroke provides extensive reach, but long unsupported rods are susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
For applications requiring the piston to maintain its position after air pressure is removed or exhausted, the standard air cushion will not act as a brake. In those scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a dimensionally interchangeable ISO 15552 unit, this model serves as a direct drop-in replacement matching the 63 mm bore, 600 mm stroke, G3/8 port, TC trunnion mount, and magnet specifications.
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 SAI63 Standard Cylinder SAI63X600STC FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure increases to 0.7 MPa, the push force reaches 2182 N.
