About the Airtac SAI63 Standard Cylinder SAI63X90S
The AirTAC SAI63X90-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 90 mm stroke provides a compact extension length, making it well-suited for mid-range actuation tasks where space is somewhat constrained but substantial thrust is still required.
This specific configuration includes a magnetic piston for position sensing and utilizes a standard carbon steel piston rod. The extruded aluminum barrel features sensor grooves on both sides, allowing for the direct mounting of CMSE or DMSE series switches without requiring additional brackets.

Where the Airtac SAI63 Standard Cylinder SAI63X90S Is Used
Clamping Fixtures
Provides 1559 N of secure clamping force at 0.5 MPa for holding heavy metal components during machining or welding processes.
Package Diverters
Uses the 90 mm stroke to rapidly actuate diverting arms on packaging lines, operating reliably at speeds up to 800 mm/s.
Press Ejection
Delivers consistent mid-stroke ejection of formed parts from automated presses, utilizing the magnetic piston for timing confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63X90S the Right Cylinder?
Selecting this 63 mm bore over the smaller 40 mm option significantly increases thrust, jumping from 628 N to 1559 N at 0.5 MPa. If your application requires even less force, stepping down to a 50 mm bore yields 982 N. Because the 90 mm stroke is relatively short, rod-bearing bending is minimal, though external guides should still be used to manage any direct side loads.
As a dimensionally interchangeable ISO 15552 cylinder, this unit serves as a drop-in replacement matching the 63 mm bore, 90 mm stroke, PT G3/8 port, and standard mounting accessory dimensions. If the machinery must maintain a load position during a loss of air pressure, an external rod lock or the SAIL variant is required, as standard air cushions only decelerate the piston at stroke end and cannot hold loads.
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 SAI63X90S FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X90-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 cylinders with a 63 mm bore, 90 mm stroke, and G3/8 port.
