Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 135mm 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 SAIJ160X135-10
The AirTAC SAIJ160X135-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. The built-in rear stopper allows you to fine-tune the effective travel down to a 125-135 mm window, perfect for dialing in exact end positions during commissioning without adding external stops.
This 160 mm bore unit uses a G3/4 port and a robust 40 mm carbon steel rod with an M36x2 thread. Because the adjuster acts purely as a mechanical stop and the variable air cushions handle deceleration, neither component will hold a load without live air pressure. For position holding, consider the SAIL or BSAI series instead. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10 Is Used
Press Fitment Tuning
Dial in the exact 125-135 mm travel window during machine commissioning to perfect heavy press fits without machining custom spacers.
Product Size Changeover
Quickly adapt the cylinder's end-stop on automated lines when switching between different product heights or widths.
High-Force Positioning
Leverage the 14074N push force to move heavy assemblies into place while retaining the ability to trim the stroke by 10 mm.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10 the Right Cylinder?
Select this 160 mm bore adjustable cylinder when your application requires high force and precise end-position tuning at machine setup. If you need slightly less thrust, stepping down to a 125 mm bore yields 8590N push force at 0.7 MPa, whereas stepping up to a 200 mm bore provides 21991N. Choose the SAIJ over a fixed-stroke SAI when you anticipate product changeovers that require variable end-stops rather than swapping the entire cylinder.
To replace an ISO 15552 cylinder, match the 160 mm bore, 135 mm stroke, 10 mm adjustment range, G3/4 PT ports, and your required mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Although 135 mm is below the 300 mm side-load threshold, the heavy 40 mm rod and M36x2 thread handle substantial side loads, though an external guide is still recommended for heavy radial loads. No magnet is specified for this configuration.

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 SAIJ160X135-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 135 mm stroke by up to 10 mm, providing a usable travel window of 125-135 mm. It sets the end position and the air cushions handle deceleration, but it does not lock or hold the load without continuous air pressure.
At 0.7 MPa, this double-acting cylinder provides a push force of 14074N and a pull force of 9425N. It can deliver up to 18095N of push force at the maximum operating pressure of 0.9 MPa.
