Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 210mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30
The AirTAC SAIJ100X210-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 180-210 mm usable travel window, letting you dial back the nominal 210 mm stroke by up to 30 mm during machine commissioning. In the 100 mm bore class, it delivers 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops, while the variable air cushions at both ends manage deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30 Is Used
Product Changeover Positioning
Dial in the exact 180-210 mm end-stop on packaging lines when switching to different carton sizes, avoiding physical cylinder swaps.
Commissioning End-Tuning
Fine-tune the retract position during machine setup to align tooling perfectly, using the 30 mm adjustment range to absorb mechanical tolerances.
Heavy-Duty Clamping
Apply up to 7068 N of push force at 0.9 MPa for holding heavy workpieces, using the adjustable stop to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-30 the Right Cylinder?
Choose this 100 mm bore when 80 mm (2513 N at 0.5 MPa) lacks push power but you want to avoid the larger 125 mm footprint. The adjustable 180-210 mm window is ideal for product changeovers requiring slightly different end positions without swapping cylinders. For fixed travel needs, a standard SAI cylinder suffices.
As an ISO 15552 profile cylinder, it matches standard mounting interface dimensions. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the 210 mm stroke exceeds 200 mm, use an external guide to prevent side-load damage to the M20x1.5 rod. Note that the rear adjuster is a stop, not a lock; for load-holding without live air, select SAIL or BSAI.
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 SAIJ100BX210-30 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 210 mm down to 180 mm. It functions as a mechanical stop to set the exact end position, but it does not lock the load without live air pressure.
