About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30S
The AirTAC SAIJ160X55-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25-55 mm, allowing you to dial back the nominal 55 mm stroke by up to 30 mm during commissioning without adding external stops. It delivers a robust 14074 N push force at 0.7 MPa, making it ideal for heavy-duty positioning tasks.
This variant includes a -S magnet for position sensing with AirTAC CMSE reed or DMSE solid-state switches. It features a SUS420J2 stainless steel rod, PT tapered ports, and dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and is not a locking device.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30S Is Used
Heavy Press Tuning
Fine-tune the exact pressing depth of heavy-duty stamping or joining operations within a 25-55 mm window without swapping cylinders.
Machine Changeover
Quickly adapt end-stops during product size changeovers on a production line using the 30 mm rear adjustment screw.
Variable End-Stop Positioning
Dial in precise retraction end-positions during machine commissioning to perfect timing sequences in automated assembly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires substantial thrust—stepping down to a 125 mm bore reduces the push force to 8590 N at 0.7 MPa. The adjustable stroke is perfect for machine changeovers where exact end-of-travel positions vary slightly. Since the 55 mm stroke is relatively short, side-load stress is minimized, but the 40 mm rod and M36x2 thread handle high bending loads well.
When specifying a replacement, match the 160 mm bore, 55 mm nominal stroke, 30 mm adjustment range, PT port thread, and -S magnet. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. For applications requiring the load to be held without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster cannot hold 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 SAIJ160AX55-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N at 0.9 MPa.
The rear adjuster allows you to mechanically shorten the effective stroke from 55 mm down to 25 mm. This provides a 30 mm tuning window to set precise end-positions without needing external stops, though it functions only as a travel stop and does not lock the load.
