About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-20S
The AirTAC SAIJ63X200-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 1559 N pull force at 0.5 MPa and provides a usable travel window of 180 to 200 mm, letting you trim up to 20 mm off the nominal stroke. Equipped with a -S magnet, it supports AirTAC CMSE reed and DMSE electronic sensors for precise position feedback.
This bore uses a 20 mm rod with an M16x1.5 thread and a G3/8 port, handling speeds up to 800 mm/s. The rod is built from SUS420J2 stainless steel for superior corrosion resistance, and the extruded aluminum barrel integrates sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop for end-position tuning, not a load-holding lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-20S Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 180-200 mm window during line changeovers without adding external mechanical stops.
Variable End-Stop Positioning
Fine-tune the end-of-stroke location on packaging equipment to accommodate varying package sizes on the fly.
Sensor-Driven Automation
Leverage the integrated magnet with DMSE electronic sensors for solid-state position detection in automated assembly.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-20S the Right Cylinder?
Select this adjustable model when your application requires fine end-position tuning at commissioning or frequent product-size changeovers without physically swapping cylinders. It provides 1559 N of pull force at 0.5 MPa. If you need less force, stepping down to the 50 mm bore yields 825 N of pull at 0.5 MPa. For load-holding without live air pressure, this plain SAIJ cylinder will not suffice; consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
To match this exact configuration for an ISO 15552 replacement, specify a 63 mm bore, 200 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Since the stroke is 200 mm, it is well within standard limits and does not require external side-load guidance.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-20S FAQ
At 0.5 MPa, it provides 1559 N of pull force and 2182 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 180 to 200 mm. It is a travel stop, not a lock.
