About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30S
The AirTAC SAIJ160X75-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. Featuring a robust 160mm bore, it delivers substantial thrust up to 18095N at 0.9 MPa. The integrated rear adjuster allows you to trim the nominal 75mm stroke back by up to 30mm, creating a highly versatile 45-75mm usable travel window without swapping hardware.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. Utilizing extruded aluminum with sensor grooves on both sides, it supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Fluid supply connects via PT tapered G3/4 ports.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30S Is Used
Product Size Changeovers
Quickly reconfigure the 45-75mm travel window on packaging lines to accommodate different carton or pallet sizes without changing the cylinder.
Heavy Press Positioning
Fine-tune the end-stop for a 18095N pressing operation, ensuring exact material deformation without over-traveling during setup.
Automated Clamp Tuning
Dial in the exact clamping depth on heavy industrial fixtures, relying on the SUS420J2 rod for durability in harsh environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30S the Right Cylinder?
Select this 160mm bore cylinder when your application demands high force—stepping down to a 125mm bore yields 11045N push force at 0.9 MPa, whereas this model provides 18095N. The adjustable stroke is ideal for machine setups requiring frequent product-size changeovers, allowing operators to dial in the exact 45-75mm end-stop at commissioning rather than machining external stops. For load-holding without live air pressure, note that the rear adjuster functions strictly as a travel stop and not a lock; you must integrate an external pilot-operated check valve or select a SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 160mm bore, 75mm nominal stroke, 30mm adjustment range, PT G3/4 port thread, and the -S magnet requirement. Because the 75mm stroke is relatively short for this large bore, side-loading is less of a concern than with long strokes, but the 40mm rod diameter and M36x2 thread provide excellent mechanical rigidity to handle heavy loads.
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 SAIJ160AX75-30S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 30mm. This creates a usable travel window of 45-75mm, allowing you to fine-tune the end position at commissioning. The adjuster only sets the travel end and does not lock the load without live air.
At an operating pressure of 0.9 MPa, the SAIJ160X75-30-S provides a push force of 18095N and a pull force of 9425N. It operates efficiently at speeds between 30-500 mm/s and uses PT tapered G3/4 ports.
