About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-30S
The AirTAC SAIJ160X650-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 620-650 mm usable travel window. It delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa. The barrel is extruded aluminum with sensor grooves on both sides, and this version includes a magnet for CMSE reed and DMSE electronic switches.
This model uses a SUS420J2 stainless steel rod (code A) for corrosion resistance and features PT tapered ports. The rear adjuster acts solely as a travel stop to fine-tune end positions during commissioning; it is not a lock and cannot hold the load without live air pressure. For load-holding without live air, consider an external rod lock or the SAIL/BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-30S Is Used
Variable End-Position Tuning
Dial in the exact retract distance between 620 and 650 mm during machine commissioning to accommodate varying workpiece heights without machining new hard stops.
Product Size Changeover
Quickly adjust the stroke end-point on a packaging line when switching between different product sizes, using the rear screw to fine-tune the travel window on the fly.
Heavy-Duty Forming Setup
Leverage the 14074 N push force at 0.7 MPa for large-scale pressing or forming operations, making micro-adjustments to the travel limit to optimize cycle consistency.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-30S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 10053 N push force at 0.5 MPa, stepping up from a 125 mm bore that provides 6136 N. The 30 mm adjustable stroke is ideal for product changeovers, allowing you to dial back the 650 mm nominal stroke to exactly 620 mm without swapping hardware or adding external stops. Because the stroke is 650 mm, the long unsupported rod requires an external guide to prevent excessive side-loading and premature wear.
This SAIJ configuration includes a -S magnet for position sensing, PT ports, and SUS420J2 rod material. It is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If you need a fixed end-stop without the adjustment feature, the standard SAI series is the alternative.

- ✓ 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 SAIJ160AX650-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At 0.9 MPa, the push force increases to 18095 N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 620 to 650 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
