About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-75S
The AirTAC SAIJ160X300-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 300 mm travel back by up to 75 mm. This creates a highly flexible 225-300 mm usable stroke window, letting you dial in the exact retract end-position during commissioning without swapping out the barrel or adding bulky external stops. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 14074 N of push force at 0.7 MPa.
Because this is a profile cylinder with an extruded aluminum barrel, it integrates sensor grooves on both sides for flush mounting of CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel limit, working in tandem with the 50 mm air cushions at both ends to decelerate the load. It does not function as a lock; if your application requires true load-holding without live air pressure, you should explore the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-75S Is Used
Product Changeovers
Dial in the 225-300 mm travel window during format size changes on packaging lines without physically swapping cylinders or repositioning hard stops.
Commissioning Calibration
Fine-tune the exact retract end-position during machine setup to perfectly align heavy 14074 N loads without mechanical shimming.
High-Force Positioning
Move heavy pallets or lifts using the robust 160 mm bore, relying on the rear stopper to set precise motion limits safely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-75S the Right Cylinder?
When selecting this 160 mm bore, you are stepping into a high-force tier, generating 14074 N push at 0.7 MPa, which is a significant jump from the 100 mm bore that provides 5497 N. If your machinery does not require that much thrust, dropping to a smaller bore saves space and air consumption. Conversely, if you need to move heavier masses, the 200 mm bore offers 21991 N. The 75 mm adjustment range is particularly valuable for product size changeovers on a line, allowing operators to set new retract distances on the fly.
For an exact ISO 15552 replacement, match the 160 mm bore, 300 mm nominal stroke, 75 mm adjustment code, PT port thread, and the -S magnet option. Keep in mind that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. Because the stroke is 300 mm, the long unsupported piston rod is susceptible to side-loading; always use an external guide rail to prevent premature seal wear and binding, even with the sturdy M36x2 rod thread.
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 SAIJ160BX300-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 14074 N of pull force. It can reach a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to mechanically shorten the 300 mm nominal stroke by up to 75 mm, providing a usable travel window of 225-300 mm. This stopper sets the end position but does not lock the load without live air pressure.
