Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 800mm 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 SAIJ160BX800-40
The AirTAC SAIJ160X800-40 is a double-acting ISO 15552 profile cylinder featuring an 800 mm nominal stroke and a rear-mounted adjuster screw that permits up to 40 mm of end-position trimming, yielding a usable travel window of 760 to 800 mm. Driven through PT tapered G3/8 ports, it generates a substantial 10053 N pull force at 0.5 MPa. The piston rod is constructed from SUS304 stainless steel, offering excellent corrosion resistance for harsh or washdown manufacturing environments.
This unit incorporates variable air cushions at both ends, each providing 50 mm of cushioning length to smoothly decelerate the heavy 160 mm bore payload across its 30-500 mm/s operating speed range. The extruded aluminum barrel includes dual-sided sensor grooves, and the mounting interface strictly supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. It is important to note that the rear adjuster functions purely as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40 Is Used
Heavy Assembly Line Changeover
Dial in the 760-800 mm retract stop on the fly when switching between heavy machinery frames of slightly different depths on the same production line.
Bulk Pallet Positioning
Provides a robust 10053 N pull force to index loaded pallets, with the rear screw allowing precise end-stop calibration for varying pallet dimensions.
Large Press Feeding
Feeds heavy materials into a hydraulic press, using the 40 mm adjustment window to fine-tune the retracted home position without reprogramming the motion controller.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40 the Right Cylinder?
Select this 160 mm bore adjustable-stroke cylinder when your application requires fine-tuning the retract end-position during commissioning or product-size changeovers without swapping out the entire barrel or adding external stops. If your process needs a lower force class, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N.
Because this model features an 800 mm stroke, the M36x2 piston rod is highly susceptible to side-loading; an external guide rail must be incorporated to prevent premature seal wear and rod bending. For any requirement to hold a load securely in place without continuous air pressure, this standard SAIJ adjuster is insufficient—consider the SAIL pneumatic lock or BSAI clamp-lock series instead. Dimensionally interchangeable per ISO 15552, this SKU is configured with a PT port, SUS304 rod, no magnet, and a 40 mm adjustment range.

- ✓ 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 SAIJ160BX800-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. Its operational speed range is 30-500 mm/s.
A rear external screw acts as a mechanical stop, allowing you to shorten the effective stroke from the 800 mm nominal length by up to 40 mm, creating a usable travel window of 760 to 800 mm. This adjuster only sets the travel end and does not lock or hold the load without live air pressure.
