About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-20S
The AirTAC SAIJ160X55-20-S is a double-acting, adjustable-stroke profile cylinder built to ISO 15552 dimensional standards. It features a 160 mm bore generating 10053 N of push force at 0.5 MPa, combined with a 55 mm nominal stroke that can be fine-tuned rearward by up to 20 mm, yielding an effective 35-55 mm travel window. The extruded aluminum barrel includes sensor grooves on both sides, and this variant includes a magnet for position detection.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel, and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to trim the retract end-position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, a SAIL or BSAI series cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-20S Is Used
Machine Setup & Changeover
Dial in the exact 35-55 mm end-stop during commissioning to accommodate new product dimensions without physically replacing the cylinder or adding external stopper blocks.
High-Force Clamping
Leverage the 14074 N push force at 0.7 MPa to securely clamp heavy workpieces, using the rear adjuster to fine-tune the clamping depth precisely.
End-Position Tuning
Compensate for mechanical wear or tooling variations by adjusting the retract travel end-point in the field, ensuring precise positioning without re-engineering the assembly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-20S the Right Cylinder?
Choose this 160 mm bore when your application demands high thrust—10053 N at 0.5 MPa or 14074 N at 0.7 MPa. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa, saving footprint and air consumption. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers without swapping the cylinder, unlike a fixed-stroke SAI model. When matching ISO 15552 replacements, verify the 160 mm bore, 55 mm stroke, 20 mm adjustment range, PT G3/4 ports, and the -S magnet option. Although the stroke is short, the 40 mm rod diameter handles substantial side loads, but any long unsupported tooling should still use an external guide.

- ✓ 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 SAIJ160AX55-20S 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 0.7 MPa, the push force increases to 14074 N.
The rear mechanical stopper allows you to shorten the nominal 55 mm stroke by up to 20 mm, creating an adjustable 35-55 mm travel window. This enables fine-tuning of the end position at commissioning without needing a different cylinder.
