About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-30
The AirTAC SAIJ50X160-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the travel window from 130 to 160 mm without adding external stops. It delivers a robust 982 N of push force at 0.5 MPa, making it well-suited for medium-duty handling. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.
This specific configuration incorporates an SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in the exact end position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-30 Is Used
Machine Changeover
Dial in the 130-160mm travel window during product size changes to set new end positions quickly without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract end position at commissioning using the rear screw, avoiding the need for external mechanical stops.
Material Handling
Provides 982N of push force at 0.5MPa for diverting or positioning medium-weight packages on a production line.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-30 the Right Cylinder?
Choose this 50 mm bore when your application requires a 982 N push force at 0.5 MPa, stepping up from the 40 mm bore which provides 628 N. The 30 mm adjustment range is ideal for product changeovers where the precise end-of-stroke position varies slightly, saving you from swapping out the entire cylinder. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.
Because the 160 mm stroke is below the 300 mm threshold, side-load stress on the 20 mm rod is moderate, though an external guide is still recommended for heavy lateral loads. Remember that the air cushions at both ends decelerate the travel but do not function as a brake; live air is required to maintain position. This cylinder is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ50 Adjustable Cylinder SAIJ50AX160-30 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster screw allows you to shorten the nominal 160 mm stroke by up to 30 mm, creating a usable travel window of 130 to 160 mm. This stopper sets the end position but does not lock the load without live air pressure.
