About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-10
The AirTAC SAIJ200X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suitable for heavy-duty operations. The integrated rear stopper allows you to fine-tune the effective travel window down to 145-155 mm, providing precise end-position control without adding external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is non-magnetic and will not support CMSE or DMSE position switches. Speeds reach 30-500 mm/s, supported by 50 mm air cushions at both ends to decelerate the heavy 200 mm piston smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-10 Is Used
Heavy Pressing Operations
Applies 28274N of thrust at 0.9 MPa for heavy assembly pressing, using the 10 mm rear adjuster to dial in the exact 145-155 mm contact distance.
Machine Changeover
Allows operators to fine-tune the end-stop position during product size changeovers on a line without physically swapping the actuator or adding external stopper blocks.
High-Force Clamping
Secures large industrial components during machining, relying on the SUS304 rod for corrosion resistance in challenging manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-10 the Right Cylinder?
Select this 200 mm bore actuator when an application demands extreme force—up to 3204 kgf at 1.0 MPa—alongside a 10 mm adjustable travel window for commissioning flexibility. If you need slightly less force, stepping down to a 160 mm bore yields 18095N of push force at 0.9 MPa, but the SAIJ200X155-10 is required for the most demanding pressing or clamping tasks. The rear adjuster acts strictly as a travel stop; it does not hold the load without live air pressure. For true fail-safe load holding, consider an AirTAC SAIL or BSAI locking cylinder.
This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. When replacing a cylinder, verify the 155 mm stroke, 10 mm adjustment, PT G3/4 port, and SUS304 rod material. Because the stroke is under 300 mm, side-load stress is manageable, but the substantial weight of a 200 mm bore still necessitates robust mounting.

- ✓ 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 SAIJ200BX155-10 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274N and a pull force of 15080N. At 1.0 MPa, it reaches a maximum push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 155 mm stroke by up to 10 mm. This creates a usable travel window of 145-155 mm for fine-tuning the end position at commissioning without replacing the cylinder.
