About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10
The AirTAC SAIJ160X185-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 175-185 mm, allowing you to dial back the 185 mm nominal stroke by up to 10 mm during commissioning. In the 160 mm bore class, it delivers substantial thrust, generating 18095 N of push force at 0.9 MPa and 14074 N at 0.7 MPa.
This heavy-duty actuator utilizes a 40 mm carbon steel rod with an M36x2 thread, providing a robust interface that handles high side loads, though long unsupported strokes still require an external guide. The extruded aluminum barrel includes sensor grooves on both sides, and since no magnet is specified, position sensing requires a separate setup rather than the standard CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping the cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10 Is Used
Heavy Press Fine-Tuning
Dial in the exact 175-185 mm travel end during machine setup to accommodate material thickness variations without installing external physical stops.
Product Changeover Systems
Quickly adjust the end position on packaging or forming lines when switching product sizes, saving commissioning time by using the built-in rear stopper.
High-Force Positioning
Leverage the 18095 N push force at 0.9 MPa to move heavy jigs or assemblies into their final retracted position with repeatable precision.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10 the Right Cylinder?
Choose this 160 mm bore actuator when an application demands high force combined with precise end-position tuning at commissioning or during product changeover. If you need slightly less thrust, stepping down to the 125 mm bore yields 11045 N of push force at 0.9 MPa, while stepping up to the 200 mm bore provides 28274 N. The adjustable stroke prevents the need to bolt on external stops or swap cylinders for minor travel changes.
For an exact ISO 15552 replacement, match the 160 mm bore, 185 mm stroke, 10 mm adjustment range, PT tapered port threads, and the standard carbon steel rod. Because this is a basic double-acting cylinder, the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For load-holding without continuous pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

- ✓ 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 SAIJ160X185-10 FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At 0.7 MPa, it delivers a push force of 14074 N.
The rear adjuster screw lets you shorten the 185 mm nominal stroke by up to 10 mm, creating a usable travel window of 175-185 mm. It acts as a mechanical stop to fine-tune the retract end position without replacing the cylinder.
