About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30
The AirTAC SAIJ160X210-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 210 mm nominal stroke by up to 30 mm for a precise 180-210 mm usable travel window. Built with an extruded aluminum barrel, it delivers massive thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at 0.5 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and is fitted with PT tapered ports. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30 Is Used
Heavy Press Tuning
Dial in the exact 180-210 mm end position during machine commissioning to accommodate varying material thicknesses without adding external stops.
Product Changeover
Rapidly adjust the retract stroke by up to 30 mm on a packaging line when switching to a different pallet or fixture size.
Robotic End Effectors
Utilize the 18095 N push force at 0.9 MPa for heavy gripping tasks while relying on the fine-tune screw to set precise clamping limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30 the Right Cylinder?
Choose this 160 mm bore when a 125 mm cylinder (providing 8590 N push at 0.7 MPa) lacks the necessary force, but a 200 mm bore would be excessive. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops for quick product changeovers without swapping hardware. Because the nominal stroke is 210 mm, external side-load guides are recommended to protect the 40 mm rod and M36x2 thread from excessive deflection.
For a true ISO 15552 replacement match, verify the 160 mm bore, 210 mm stroke, 30 mm adjustment range, PT port thread, and the required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that this SKU lacks a magnet; adding an -S suffix is required if you need to mount CMSE reed or DMSE electronic sensors.
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 SAIJ160 Adjustable Cylinder SAIJ160BX210-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 14274 N. At 0.5 MPa, it provides 10053 N of push force.
The rear adjuster acts as a mechanical stop that shortens the 210 mm nominal stroke, creating a 180-210 mm travel window. It sets the end position but does not hold the load without continuous air pressure.
