About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10
The AirTAC SAIJ100X210-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end position. With a nominal 210 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 200 to 210 mm. This bore delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This SKU 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 for flexible mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a travel stop to dial in the exact end position during commissioning, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10 Is Used
Machine Changeover
Quickly adjust the retract end-position by up to 10 mm when switching product sizes on a packaging line, avoiding the need to physically swap cylinders.
Heavy-Duty Positioning
Leverage 7068 N of push force at 0.9 MPa to move heavy fixtures into place, using the rear stopper to fine-tune the final resting coordinates.
Assembly Line Stops
Set precise physical boundaries for large pallets on an assembly conveyor, relying on the robust 25 mm rod and PT tapered ports for reliable operation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10 the Right Cylinder?
Choose this 100 mm bore when your application requires higher thrust than the 80 mm version (which provides 2513 N at 0.5 MPa), but you want to avoid the larger footprint of a 125 mm cylinder. The 10 mm adjustment window is perfect for dialing in precise end positions during machine setup or product changeover, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops.
For a direct ISO 15552 replacement, match the 100 mm bore, 210 mm stroke, PT port threads, and SUS304 (B) rod material. Note that this model does not include a magnet for sensors. Because the stroke is under 300 mm, side-load stress is moderate, but long unsupported loads should still use an external guide. If your machine requires true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ rear stopper is not a locking device.
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 SAIJ100BX210-10 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N. The operational speed range for this 100 mm bore is 30-800 mm/s.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 210 mm down to 200 mm. This creates a 200-210 mm usable window for fine-tuning the end position at commissioning without changing the cylinder.
