About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-20S
The AirTAC SAIJ160X700-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 680 to 700 mm. Built with a 160 mm bore, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for position detection via CMSE reed or DMSE electronic solid-state switches.
This model utilizes a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw allows you to fine-tune the retract end position at commissioning without adding external physical stops. The adjuster functions strictly as a travel stop and deceleration point, meaning it will not hold the load safely without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-20S Is Used
Heavy Press Tuning
Dial in the exact 680 to 700 mm retract position during heavy press commissioning to accommodate varying tooling heights without machining new spacers.
Product Changeover
Quickly adjust the end-stop for a new pallet size on a high-thrust conveyor line, using the rear screw instead of swapping the entire cylinder.
Large Assembly Fixtures
Leverage the 14074 N push force and SUS304 rod to securely position large stainless steel components in washdown-class manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-20S the Right Cylinder?
Choose this 160 mm bore if your application requires heavy thrust in the 14000 N range at 0.7 MPa; stepping down to a 125 mm bore yields 8590 N of push force, while stepping up to a 200 mm bore provides 21991 N. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise end-position tuning during machine setup. Because the stroke is 700 mm, the 40 mm diameter rod and M36x2 thread can handle significant side loads, but an external guide is still recommended to prevent binding over this long unsupported travel.
For drop-in ISO 15552 replacement, match the 160 mm bore, 700 mm stroke, 20 mm adjustment range, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the air cushion and rear stopper do not act as a lock; for load-holding without live pressure, specify an AirTAC SAIL or BSAI series cylinder.
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 SAIJ160BX700-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore double-acting cylinder generates a push force of 14074 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 700 mm down to 680 mm. It allows fine end-position tuning at commissioning but does not lock the load without continuous air pressure.
