Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-20
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 200mm stroke, G3/4 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 SAIJ160 Adjustable Cylinder SAIJ160BX200-20
The AirTAC SAIJ160X200-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 160 mm bore and a 200 mm nominal stroke, yielding a usable travel window of 180-200 mm by dialing the stopper back up to 20 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The SUS304 stainless steel rod (code B) provides excellent corrosion resistance for harsh environments.
Delivering substantial thrust, this model outputs 14074 N push force at 0.7 MPa and 18095 N at 0.9 MPa. It operates at speeds of 30-500 mm/s and uses a G3/4 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for position holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-20 Is Used
Machine Setup Tuning
Dial in the exact retract end-position during initial commissioning without machining new mounting plates or adding external stopper blocks.
Product-Size Changeovers
Quickly shorten the effective stroke by up to 20 mm on a packaging line when switching to a slightly smaller product format.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy assemblies into a precisely adjustable end-stop location.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-20 the Right Cylinder?
Choose this 160 mm bore cylinder when an application demands high force combined with variable end stops, such as during product-size changeovers on a line. If the full 18042 N pull force at 0.5 MPa is excessive, stepping down to the 125 mm bore yields 5734 N pull, while stepping up to the 200 mm bore provides 15080 N pull. The adjustable stroke is favored over a fixed SAI cylinder when commissioning requires fine-tuning the retract position.
To replace an ISO 15552 cylinder, match the 160 mm bore, 200 mm stroke, 20 mm adjustment, G3/4 PT port, and SUS304 rod material. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Although the 200 mm stroke is relatively short for this bore, always ensure external guides are used to manage side loads on long unsupported strokes.
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 SAIJ160BX200-20 FAQ
At an operating pressure of 0.5 MPa, it provides 10053 N push force and 9425 N pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective travel back from the 200 mm nominal stroke, creating a 180-200 mm usable window. It decelerates the stroke end but does not lock the load without live air pressure.
