About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40
The AirTAC SAIJ200X1000-40 is a double-acting ISO 15552 profile cylinder engineered for high-force pneumatic applications. It integrates a rear stroke adjuster that allows you to fine-tune the effective travel down to 960 mm from the 1000 mm nominal length. This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads.
Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore profile cylinder is built to handle heavy loads. The 1000 mm stroke is a non-standard, made-to-order length for this bore, and the 40 mm adjustment window is ideal for dialing in exact end positions during commissioning without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40 Is Used
Heavy Machinery Positioning
Dial in the 960-1000 mm travel window during heavy equipment assembly to set precise mechanical stops without fabricating custom spacers.
Large Product Changeover
Adjust the rear stopper on the fly to accommodate different pallet or product lengths on a 200 mm bore actuator pushing heavy loads.
Long-Stroke Commissioning
Fine-tune the non-standard 1000 mm stroke end-position to perfect timing sequences in new automated lines before locking down the setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40 the Right Cylinder?
Selecting this non-standard 1000 mm stroke configuration means you require maximum extension in a high-force package, stepping up from a 160 mm bore that provides 10053 N push at 0.5 MPa. The adjustable rear stopper is chosen over a fixed SAI cylinder when product changeovers require variable end-of-stroke positions. Because the stroke is 1000 mm, the 40 mm rod diameter and M36x2 thread will not prevent rod sag; an external guide is strictly required to manage side loads and prevent binding.
This SKU uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Note that the rear adjuster acts only as a travel stop; for load-holding without live air pressure, specify an SAIL or BSAI cylinder.
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 SAIJ200BX1000-40 FAQ
At 0.5 MPa, this 200 mm bore cylinder delivers 15708 N of push force and 15080 N of pull force. The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster acts as an external mechanical stop, allowing you to shorten the 1000 mm nominal stroke by up to 40 mm, creating a 960-1000 mm usable travel window. It decelerates the end-of-stroke but does not lock or hold the load without live air pressure.
