About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75S
The AirTAC SAIJ160X210-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 135 to 210 mm. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa. The included -S magnet enables position feedback via AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves.
This unit features a SUS304 stainless steel rod (option B) and PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end-position during commissioning without adding external stops. It is not a locking device, so load-holding without live air requires a SAIL or BSAI cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75S Is Used
Machine Changeover
Dial in the exact retract distance during product size transitions without swapping out the entire cylinder assembly.
End-Position Tuning
Fine-tune the 135-210 mm travel window at commissioning to perfect machine timing and avoid hard mechanical crashes.
Heavy Assembly Press
Leverage the 18095 N push force at 0.9 MPa to drive heavy pressing operations while adjusting the stroke for material thickness.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75S the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore falls short at 3681 N pull (0.5 MPa) or a 200 mm bore is excessive at 15080 N. The 75 mm adjustment window is ideal for product changeovers, letting you dial back the 210 mm stroke precisely to a new shorter endpoint. For any fixed-stroke needs, a standard SAI cylinder is preferred.
To match this ISO 15552 replacement, verify the 160 mm bore, 210 mm nominal stroke, 75 mm adjustment, PT G3/4 port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 210 mm, ensure external guides support the load to prevent rod side-loading.
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 SAIJ160BX210-75S FAQ
At 0.5 MPa it provides 10053 N pull force and 14074 N push force. At 0.9 MPa, the push force reaches 18095 N.
The rear adjuster lets you mechanically shorten the 210 mm nominal stroke by up to 75 mm, creating a usable 135-210 mm travel window. It acts as a stop, not a lock.
