About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30S
The AirTAC SAIJ100X195-30-S is a double-acting ISO 15552 profile cylinder featuring a built-in rear stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks. The rear stopper mechanism allows you to fine-tune the effective travel window down from the 195mm nominal stroke, providing a precise 165-195mm adjustable range without adding external stops.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is compatible with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and the PT tapered ports ensure a tight pneumatic connection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30S Is Used
Machine Changeover
Dial in the 165-195mm travel window during product size transitions to set precise end positions without physically swapping cylinders.
Heavy Positioning
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or fixtures, using the rear stopper to fine-tune the final resting coordinate.
Sensor-Ready Automation
Utilize the integrated magnet with CMSE or DMSE switches to confirm end-of-stroke positions in washdown environments thanks to the SUS304 rod.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30S the Right Cylinder?
Select this 100mm bore cylinder when an application requires substantial thrust—stepping down to a 63mm bore yields 2805N at 0.9 MPa, whereas this model provides 7068N. The adjustable stroke is ideal for machine changeovers, allowing operators to dial in the exact 165-195mm end position at commissioning rather than swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop; it will not hold a load without live air pressure. For secure load-holding, consider an SAIL or BSAI series cylinder.
When replacing an ISO 15552 cylinder, match the 100mm bore, 195mm stroke, 30mm adjustment range, PT G1/2 ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Since the 195mm stroke approaches the mid-range of standard lengths, always ensure external guides support the load to mitigate side-load stress on the 25mm rod.
Quick checklist

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX195-30S FAQ
At a 0.9 MPa operating pressure, this 100mm bore cylinder generates 7068N of push force and 3681N of pull force. It can achieve a maximum thrust of 801 kgf at 1.0 MPa.
The rear adjuster screw lets you trim the 195mm nominal stroke by up to 30mm, creating a 165-195mm usable travel window. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
