About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30
The AirTAC SAIJ160X200-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 200 mm travel by up to 30 mm. This creates a 170-200 mm usable positioning window, allowing precise end-stop tuning during commissioning without adding external stops. Belonging to a high-thrust class, it delivers 10053 N of push force at 0.5 MPa and handles operating speeds of 30-500 mm/s.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance, a PT tapered port thread, and a robust 40 mm rod diameter with an M36x2 thread. The extruded aluminum barrel includes sensor grooves on both sides, though this unit ships without a magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30 Is Used
Heavy Press Tuning
Fine-tune the 170-200 mm retract distance during machine setup to apply exact clamping force without mechanical shims.
Product Changeovers
Quickly adjust the end-stop by up to 30 mm on a packaging line when switching to a different product size.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for high-thrust positioning tasks in environments requiring washdown resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30 the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 2513 N at 0.5 MPa) lacks the necessary force, but a 200 mm bore is physically oversized. The 30 mm adjustment range is ideal for product changeovers on a line, letting you shift the retract end-position without swapping the cylinder. For fixed-position tasks requiring no end-tuning, a standard SAI cylinder is simpler. Note that the rear screw acts purely as a travel stop, not a lock; the SAIJ cannot hold a load without live air, so for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
To replace this cylinder per ISO 15552 interface dimensions, match the 160 mm bore, 200 mm stroke, 30 mm adjustment, PT port thread, and the SUS304 rod material. Because the stroke is 200 mm, side-load stress is moderate, but the large 40 mm rod diameter handles it well; for longer unsupported strokes, always use an external guide.
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 SAIJ160BX200-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 200 mm down to 170 mm. It sets the retract end-position but does not lock the load without continuous air pressure.
