Airtac SAIJ160 Adjustable Cylinder SAIJ160X45-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X45-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 45mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X45-20S
The AirTAC SAIJ160X45-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning during commissioning. It provides a usable travel window of 25-45 mm by dailing back the 45 mm nominal stroke up to 20 mm. This bore delivers substantial thrust, yielding 9425 N of pull force at 0.5 MPa and 18095 N at 0.9 MPa.
It features a carbon steel piston rod and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this is the -S variant, it contains a magnet ready for AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X45-20S Is Used
Adjustable Pressing
Dial in the exact 25-45 mm travel window for assembly operations, ensuring precise contact force without replacing the cylinder.
Product Changeover
Quickly adapt end-stops on a machining line when switching between parts of slightly different heights.
Heavy Clamping
Leverage the 18095 N push force at 0.9 MPa to secure large workpieces, fine-tuning the clamp position via the rear adjuster.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X45-20S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy force but only short travel, such as clamping or pressing. If you need less force, stepping down to the 125 mm bore provides 5734 N of pull at 0.5 MPa. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers without physically swapping the cylinder. Since the total stroke is 45 mm, no external guide is required for side-load support.
To replace an ISO 15552 cylinder, match the 160 mm bore, 45 mm stroke, 20 mm adjustment, PT port, and the -S magnet. SAIJ uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For true load-holding without live air pressure, select the SAIL lock or BSAI clamp-lock cylinder instead of relying on the rear stopper.
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 SAIJ160X45-20S FAQ
At 0.5 MPa it provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw trims the effective travel, allowing you to shorten the 45 mm nominal stroke by up to 20 mm, creating a usable window of 25-45 mm for fine-tuning the end position.
