About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50
The AirTAC SAIJ200X290-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N of push force at 0.5 MPa. It features a rear external adjusting stopper that trims the effective stroke, providing a usable travel window of 240 to 290 mm. This allows precise end-position tuning during commissioning without swapping out the entire actuator.
Equipped with a robust 40mm piston rod and M36x2 rod threading, this model handles significant side loads, though its 290mm stroke still necessitates an external guide for optimal stability. The barrel is extruded aluminum with sensor grooves on both sides, and the rod utilizes SUS420J2 stainless steel (code A) for enhanced corrosion resistance. It operates at 30-500 mm/s and includes variable air cushions at both ends to manage kinetic energy.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50 Is Used
Heavy Machinery Setup
Dial in the 240-290mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without machining external spacers.
Product Size Changeover
Quickly adapt automated heavy-duty clamping stations to different pallet heights by rotating the rear stopper screw up to 50mm.
Long-Stroke Positioning
Manage the 290mm travel with adjustable end-stops for large material handling doors, using the M36x2 threaded rod for secure heavy-load attachment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50 the Right Cylinder?
Selecting this 200mm bore actuator provides 15708N push and 15080N pull force at 0.5 MPa; stepping down to a 160mm bore would reduce output to 10053N. The 50mm rear adjuster is chosen when a machine requires variable end-stops for rapid product-size changeovers, functioning as a travel stop rather than a load lock. For applications requiring position holding without live air pressure, a plain SAIJ is insufficient—consider an AirTAC SAIL or BSAI locking cylinder instead.
Because the stroke exceeds 300mm, supporting the load with an external guide is critical to prevent excessive rod wear. To ensure exact ISO 15552 replacement compatibility, verify the 290mm stroke, 50mm adjustment range, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this configuration omits FB, CA, CB, and CR mounts.
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 SAIJ200 Adjustable Cylinder SAIJ200AX290-50 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At a maximum 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that shortens the nominal 290mm stroke, creating a 240-290mm usable travel window. It sets the retract end position but does not lock the load without continuous air pressure.
