About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-30
The AirTAC SAIJ200X1000-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing with 28274N at 0.9 MPa and pulling with 15080N at 0.5 MPa. The integrated rear stopper allows you to fine-tune the effective travel down from the 1000mm nominal stroke to a precise 970-1000mm window without bolting on external stops.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 200mm bore unit uses PT tapered G3/4 ports and operates at 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and it supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-30 Is Used
Variable End-Stop Positioning
Dial in the 970-1000mm travel window during machine commissioning to set precise retract positions without swapping out the entire cylinder.
Product Changeover Adjustment
Quickly adapt the stroke end-position on a conveyor sorting line when switching to different package lengths, using the rear adjuster for fast setup.
Heavy-Duty Pressing
Leverage the 28274N push force at 0.9 MPa for large-scale pressing operations while fine-tuning the bottoming point to protect tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-30 the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or commissioning fine-tuning on a long 1000mm travel. Unlike a fixed SAI cylinder, the rear adjuster lets you dial in the exact 970-1000mm position during product changeovers. If your application demands less force, stepping down to a 160mm bore yields 18095N push at 0.5 MPa. Because the 1000mm stroke is long and unsupported, an external guide is required to manage side loads. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use an external rod lock, a pilot-operated check valve, or the BSAI clamp-lock cylinder. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ200BX1000-30 FAQ
At 0.9 MPa, this 200mm bore cylinder generates a push force of 28274N and a pull force of 15080N at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
The rear adjuster is a mechanical stop that lets you shorten the 1000mm nominal stroke by up to 30mm, creating a 970-1000mm usable travel window. It is a stop, not a lock, and will not hold the load without continuous air pressure.
