About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30S
The AirTAC SAIJ100X210-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 7068N push force at 0.9 MPa and provides a usable travel window of 180 to 210 mm, allowing you to dial back the nominal stroke by up to 30 mm. This eliminates the need to swap hardware when finalizing end positions during commissioning.
Equipped with a SUS304 stainless steel rod and a magnet for CMSE or DMSE sensors, it integrates seamlessly into existing setups. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends manage end-of-travel deceleration. Remember that this adjuster acts purely as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30S Is Used
Machine Setup & Changeover
Fine-tune the 180-210mm travel window during initial commissioning or product size changes without replacing the entire cylinder or bolting on external stops.
Variable End-Stop Positioning
Dial in the exact retract position for multi-stage tooling operations, leveraging the 3927N push force at 0.5 MPa for robust actuation.
Automated Assembly Lines
Integrate using the CMSE/DMSE sensor grooves on both sides of the profile barrel to confirm end-of-stroke positions in high-speed assembly equipment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30S the Right Cylinder?
Select this 100mm bore when an 80mm cylinder (providing 4523N push at 0.9 MPa) lacks thrust, but before stepping up to a 125mm unit. The adjustable 30mm window is ideal for product changeovers, letting you fine-tune the retract end-position without adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 100mm bore, 210mm stroke, 30mm adjustment, G1/2 port, and -S magnet. Because the stroke is 210mm, ensure proper external guiding to prevent side-loading on the 25mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ100 Adjustable Cylinder SAIJ100BX210-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a usable travel window of 180 to 210mm. It functions as a mechanical stop to fine-tune the end position and works alongside the air cushion for deceleration.
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
