About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX200-40S
The AirTAC SAIJ200X200-40-S is a double-acting ISO 15552 profile cylinder featuring a SUS304 stainless steel rod and an integrated rear stroke adjuster. It provides a usable travel window of 160-200 mm, allowing you to dial back the nominal 200 mm stroke by up to 40 mm during commissioning. Belonging to the largest standard bore class, it generates a substantial 15708 N pull force at 0.5 MPa and 15080 N at 0.7 MPa, making it ideal for moving massive loads.
This variant includes a piston magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, while the PT tapered port threads ensure a rigid pneumatic connection for its 30-500 mm/s operating speed.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX200-40S Is Used
Heavy Press Tuning
Dial in the exact 160-200 mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping actuators.
Product Changeover
Quickly adjust the retract end-stop on automated packaging lines when switching to a different pallet or product size, saving setup time.
Massive Load Positioning
Leverage the 15708 N pull force to shift heavy assemblies into place, using the fine adjustment to guarantee perfect alignment against a mechanical stop.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX200-40S the Right Cylinder?
Choose this 200 mm bore when 160 mm or 125 mm bores (offering 8590 N or 6136 N push force at 0.5 MPa) cannot provide the necessary thrust for heavy industrial loads. An adjustable stroke is selected over a fixed SAI cylinder when you need precise end-position tuning during machine setup or product changeover without physically swapping the actuator. The rear adjuster and variable air cushions only decelerate the travel end; they do not hold the load without live air. For fail-safe load holding without pneumatic pressure, use an external rod lock or pilot-operated check valve. To replace an ISO 15552 cylinder, match the 200 mm bore, 200 mm stroke, 40 mm adjustment, PT G3/4 port, and -S magnet.
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 SAIJ200BX200-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of pull force and 15080 N of push force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw lets you shorten the nominal 200 mm stroke by up to 40 mm, creating a 160-200 mm usable travel window. This mechanical stop fine-tunes the end position at commissioning but does not lock the load without live air pressure.
