Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100S
The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX220-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 220mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100S
It features a robust 40 mm SUS304 stainless steel rod and PT G3/4 tapered ports. The integrated rear stopper allows you to trim the effective travel, creating a 120-220 mm usable stroke window from the 220 mm nominal length. This built-in adjustability enables precise end-position tuning at commissioning without swapping out the entire cylinder or fabricating external stops.
Because this is a profile cylinder with an extruded aluminum barrel, it includes sensor grooves on both sides for position feedback. The -S magnet option supports AirTAC CMSE reed and DMSE solid-state electronic switches. The rear adjuster acts solely as a mechanical stop to set the travel end and does not hold the load without live air pressure. For applications requiring true load-holding without continuous air, consider the SAIL or BSAI series instead.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100S Is Used
Machine Changeover Tuning
Dial in the exact end-of-stroke position for different product sizes on a single line, using the 100 mm adjustment window to switch formats without physically replacing the actuator.
Variable End-Stop Assembly
Accommodate multiple part lengths in automated assembly stations by adjusting the retract stop on the fly, relying on the SUS304 rod for durability in demanding environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore's 3927 N at 0.5 MPa is insufficient but you want to avoid stepping up to the massive 200 mm bore, which provides 15708 N. The SAIJ160X220-100-S is specifically selected for machinery requiring variable end-stops during product changeovers, offering a 100 mm fine-tuning range. To match this ISO 15552 replacement, verify the 160 mm bore, 220 mm nominal stroke, 100 mm adjuster, PT G3/4 port, and the -S magnet requirement.
With a 220 mm stroke, the 40 mm SUS304 rod handles substantial side loads, but any long unsupported overhang still requires an external guide rail to prevent premature seal wear. The available mounting interfaces include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Operating speed ranges from 30-500 mm/s, supported by 50 mm variable air cushions at both ends.

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 SAIJ160BX220-100S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 220 mm nominal stroke by up to 100 mm, resulting in a 120-220 mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
