About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100S
The AirTAC SAIJ160X115-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 10053N of push force at 0.5 MPa while offering a highly versatile usable travel window of 15 to 115 mm. This wide adjustment range allows operators to dial in the exact end-of-stroke position during commissioning or product changeovers without bolting on external stops or swapping the actuator.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves. The robust 40 mm carbon steel rod and M36x2 thread provide excellent rigidity, while the PT tapered port threads ensure a tight, leak-free pneumatic connection. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100S Is Used
Multi-Format Pressing
Dial in the exact 15 to 115 mm travel window during product format changes, allowing a single heavy-duty press to accommodate multiple material thicknesses without hardware swaps.
Commissioning Calibration
Fine-tune the retract end-position during machine setup to perfect the resting state of heavy 10053N loads, ensuring precise alignment before final lock-down.
Variable Stop Assembly
Adjust the mechanical stopper on the fly to accommodate different part lengths on the assembly line, relying on the rear screw to set the exact travel limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100S the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires the 10053N thrust class but demands highly variable end-stops for product size changes. If you need less force, stepping down to the 125 mm bore yields 6136N of push force at 0.5 MPa. Choose this adjustable SAIJ variant over a fixed-stroke SAI cylinder when you need on-the-fly repositioning at the machine. Remember that the rear adjuster is a travel stop, not a lock; for true load-holding without live air pressure, you must use an external rod lock, a pilot-operated check valve, or AirTAC's BSAI clamp-lock series.
When replacing an ISO 15552 cylinder, match these exact parameters: 160 mm bore, 115 mm nominal stroke, 100 mm adjustment range, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). Although the 115 mm stroke is relatively short, the heavy 40 mm rod handles high side loads, but any long unsupported tooling should still use an external guide rail.
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 SAIJ160X115-100S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053N of push force and 9425N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 18095N.
The rear adjuster allows you to shorten the 115 mm nominal stroke by up to 100 mm, creating a usable travel window of 15 to 115 mm. This mechanical stop only sets the travel end and does not hold the load without live air pressure.
