About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-20S
The AirTAC SAIJ160X550-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 10053 N of push force at 0.5 MPa and features a 550 mm nominal stroke that can be fine-tuned backward by up to 20 mm, creating a precise 530-550 mm usable travel window. This built-in adjustability allows you to dial in the retract end position during commissioning without swapping out the cylinder or adding external stopper blocks.
Configured with a SUS420J2 stainless steel rod (material code A) and a magnet for position sensing, this model accepts CMSE reed and DMSE electronic switches in its dual-side sensor grooves. Fluid is filtered air operating at 0.15-1.0 MPa. The extruded aluminum barrel design integrates adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-20S Is Used
Product Changeovers
Dial the retract position back by up to 20 mm to accommodate new product lengths on an assembly line without changing the cylinder.
Heavy Forming End-Stops
Leverage 10053 N of push force at 0.5 MPa for pressing applications, using the rear stopper to set exact 530-550 mm travel limits.
Automated Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfect tooling alignment before locking down the setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-20S the Right Cylinder?
Choose this 160 mm bore when an application requires substantial thrust—10053 N push at 0.5 MPa—stepping up from a 125 mm bore (6136 N) to handle heavier payloads. The adjustable stroke is ideal for product changeovers on a line, letting operators trim the 550 mm travel back by 20 mm to accommodate varying part sizes without mechanical rebuilds. Because the stroke is 550 mm, the M36x2 piston rod should be paired with an external guide to prevent excessive side-loading on the seals.
To replace an ISO 15552 cylinder, match the 160 mm bore, 550 mm stroke, 20 mm adjustment, PT tapered port threads, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding without pressure, use an AirTAC SAIL locking cylinder or a BSAI clamp-lock. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160AX550-20S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster acts as an external stopper that shortens the effective stroke by up to 20 mm. This creates a 530-550 mm usable travel window, allowing you to fine-tune the end position without replacing the cylinder. Note that it is a stop, not a lock, and cannot hold a load without live air pressure.
