About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-30S
The AirTAC SAIJ200X225-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches. Its SUS420J2 stainless steel rod provides excellent durability and corrosion resistance for demanding environments.
This model features a 225mm nominal stroke that can be fine-tuned down by up to 30mm, creating a precise 195-225mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-500 mm/s and utilizes PT tapered port threads (G3/4) for secure pneumatic connections.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-30S Is Used
Heavy Machinery Setup
Fine-tunes the 195-225mm travel window during heavy machinery commissioning, allowing operators to dial in exact end positions without machining external stopper blocks.
Product Line Changeover
Enables rapid adjustment of end-stops on automated lines handling varying product sizes, leveraging the 15708N force capacity for massive forming or pressing tasks.
Variable Positioning Stops
Provides a rear mechanical stop to set precise retraction limits in large-scale material handling, utilizing the SUS420J2 rod for superior wear resistance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-30S the Right Cylinder?
Select this 200mm bore cylinder when an application requires extreme force combined with adjustable end-positioning, avoiding the need to swap physical components during product changeovers. If 15708N push force at 0.5 MPa exceeds your requirements, stepping down to a 160mm bore yields 10053N, whereas fixed-stroke needs are handled by the standard SAI series. For this 225mm stroke, the robust 40mm rod and M36x2 thread handle substantial side loads, though an external guide is recommended for heavy off-center loads.
To match this exact configuration, specify the 200mm bore, 225mm stroke, 30mm adjustment, PT port threads, SUS420J2 rod material, and the -S magnet. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX225-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, providing a usable travel window of 195-225mm from the 225mm nominal stroke. This stopper only sets the travel end and does not lock the load without continuous air pressure.
