About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX70-10S
The AirTAC SAIJ200X70-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. Based on a 70mm nominal stroke and a 10mm adjustment screw, it provides a usable travel window of 60 to 70mm without requiring external stops. It delivers substantial thrust, generating 15708N of push force and 15080N of pull force at 0.5MPa, making it suitable for heavy-duty positioning tasks.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is fully dimensionally interchangeable with ISO 15552 cylinders. The rear adjuster acts purely as a travel stop to set the retract end, and like the integrated air cushions, it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX70-10S Is Used
Heavy Press Tuning
Dial in the exact 60-70mm travel end-stop during heavy press commissioning to ensure precise clamping without swapping cylinders.
Product Changeover
Quickly adjust the retract position on packaging lines during product size transitions, using the rear screw to fine-tune the stroke.
Corrosive Positioning
Leverage the SUS304 stainless steel rod and heavy 15708N push force to move heavy jigs in washdown or corrosive factory environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX70-10S the Right Cylinder?
Select this 200mm bore cylinder when your application requires up to 15708N of push force at 0.5MPa, and step down to the 160mm bore (offering 10053N push force) if your load requirements are lighter. The adjustable stroke is ideal for machine setups requiring precise variable end-stops, whereas a fixed-stroke SAI cylinder is better for simpler, unchanging movements. Remember that the adjuster is a stop, not a lock; for load-holding without live air pressure, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 200mm bore, 70mm stroke, 10mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. The 40mm rod and M36x2 thread provide high rigidity, but even with a robust rod, long unsupported strokes require an external guide to manage side loads.
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 SAIJ200BX70-10S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum thrust of 3204 kgf at 1.0MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 60 to 70mm from the 70mm nominal stroke. It functions as a mechanical stop and does not lock the load without continuous air pressure.
