About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-40S
The AirTAC SAIJ63X200-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel, creating a precise 160-200mm usable window for commissioning flexibility. It delivers 1559N of pull force at 0.5MPa and includes a magnet for position sensing.
This variant uses a SUS420J2 stainless steel rod (option A) for corrosion resistance and features tapered PT ports. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches without extra hardware.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-40S Is Used
Machine Changeover
Rapidly adjust the retract end-position by up to 40mm during product size changes on a packaging line without replacing the cylinder.
End-Stop Tuning
Fine-tune the final resting position of the tooling at commissioning to absorb mechanical tolerances and achieve exact clamping contact.
Variable Test Travel
Dial back the stroke window from 200mm down to 160mm to test different engagement depths in laboratory or prototype equipment.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-40S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (825N pull at 0.5MPa) is insufficient but an 80mm bore (2268N pull) would be overkill. The 40mm adjustment range is ideal for product changeovers, allowing you to dial in the end stop without swapping the cylinder or adding external stops. For load-holding without live air pressure, note that the rear adjuster is only a travel stop, not a lock; consider SAIL or BSAI cylinders, or an external pilot-operated check valve.
When replacing an ISO 15552 cylinder, match the 63mm bore, 200mm stroke, 40mm adjustment, G3/8 PT ports, and the -S magnet. The 200mm stroke exceeds 150mm, so use an external guide to prevent side-loading damage to the M16x1.5 rod thread.
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 SAIJ63AX200-40S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke by up to 40mm. This gives the piston a usable travel window between 160mm and 200mm. The standard air cushions at both ends handle deceleration, but the adjuster does not lock the load without live air.
At 0.5MPa operating pressure, it provides 1559N pull force and 2182N push force. The -S suffix indicates an integrated magnet, allowing direct mounting of AirTAC CMSE reed switches or DMSE electronic solid-state sensors along the dual barrel grooves.
