About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20
The AirTAC SAIJ200X200-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, engineered for heavy-duty applications requiring 15708N of push force at 0.5MPa. It features a robust 40mm SUS304 stainless steel rod and PT tapered ports. By integrating an external adjusting screw at the rear, this model provides a usable travel window of 980-1000mm, allowing you to trim the effective stroke by up to 20mm without swapping the cylinder.
This made-to-order 1000mm stroke variant utilizes an extruded aluminum barrel with sensor grooves on both sides, maintaining a true profile design rather than a tie-rod construction. The rear stopper enables precise end-position tuning during commissioning or product changeovers, functioning strictly as a travel stop and not a load-holding lock. For applications requiring position holding without live air pressure, external rod locks or related SAIL pneumatic lock cylinders are required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20 Is Used
Heavy Press Tuning
Dial in the exact 980-1000mm end-stop during heavy press commissioning to accommodate material thickness variances without adding external stops.
Large Product Changeover
Adjust the retract position on the fly for different pallet sizes on a conveyor line, utilizing the 20mm trim window to avoid reprogramming fixed stops.
Automated Assembly Setup
Fine-tune the stroke end-position during automated assembly machine setup, ensuring precise alignment of heavy 200mm bore actuation components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20 the Right Cylinder?
Selecting this 200mm bore cylinder is ideal when your application demands substantial thrust, such as 15708N push and 15080N pull at 0.5MPa, stepping up significantly from a 160mm bore that yields 10053N. The adjustable 980-1000mm travel window is chosen over a fixed-stroke SAI cylinder when machinery requires fine-tuning of the retract end-position during setup or when accommodating slight dimensional variances in product lines. To match this exact configuration, specify the 200mm bore, 1000mm stroke, 20mm adjustment, PT ports, SUS304 rod, and no magnet.
Because this model features a 1000mm stroke, the extended 40mm rod is subject to increased side-loading risks; an external guide mechanism is strongly recommended to prevent premature seal wear. The SAIJ series supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Operating speed for this bore size ranges from 30-500mm/s.
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 SAIJ200BX1000-20 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it achieves a maximum push force of 3204kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 1000mm stroke by up to 20mm, resulting in a usable travel window of 980-1000mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
