Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 650mm 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 SAIJ160BX650-40
The AirTAC SAIJ160X650-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel by up to 40 mm. This yields a usable 610-650 mm end-position window, ideal for fine-tuning machinery at commissioning without adding external stops. It delivers a robust 10053 N pull force at 0.5 MPa and uses a SUS304 stainless steel rod for superior corrosion resistance.
This heavy-duty actuator features a G3/4 PT tapered port and variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning electronic DMSE or reed CMSE position switches cannot be fitted without adding one.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40 Is Used
Heavy Press Tuning
Fine-tune the 610-650 mm retraction end-stop on heavy presses during setup, avoiding the need to swap out a fixed-stroke SAI cylinder for minor position changes.
Product Changeover
Adjust the effective travel window quickly on automated lines when product sizes change, using the 40 mm rear screw to accommodate new dimensions without external stopper blocks.
Large Assembly Jigs
Drive large assembly jigs requiring 10053 N of pull force at 0.5 MPa, relying on the M36x2 threaded SUS304 rod to withstand harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40 the Right Cylinder?
Choose this 160 mm bore actuator when a 10053 N pull force at 0.5 MPa (or 18095 N push at 0.9 MPa) is required alongside a variable end-stop. If your application needs less force, stepping down to the 125 mm bore yields 5734 N pull at 0.5 MPa. The rear adjuster acts purely as a mechanical travel stop to set deceleration limits; it does not hold the load without live air pressure. For true fail-safe load holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
Because the 650 mm stroke is long, an external guide is recommended to prevent excessive side-loading on the 40 mm SUS304 rod, even with its robust M36x2 thread. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX650-40 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 650 mm down to 610 mm. This stopper only sets the end position and decelereration; it does not lock the load without live air pressure.
