Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-10S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 170mm 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 SAIJ160X170-10S
The AirTAC SAIJ160X170-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers substantial thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. By turning the rear screw, you can trim the effective travel within a precise 160 to 170 mm window, allowing exact end-position tuning without swapping out the entire actuator.
This unit features a standard carbon steel piston rod and a PT tapered port thread. It includes a magnet (-S) for electronic DMSE or reed CMSE position sensing, and relies on variable air cushions at both ends to decelerate heavy loads. The adjuster acts purely as a travel stop, so an external rod lock or pilot-operated check valve is required if you need to hold position without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-10S Is Used
Press Stroke Calibration
Fine-tune the 160 to 170 mm travel window during initial commissioning to achieve the exact contact depth for high-force pressing operations without adding external shims.
Product Size Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slight variations in incoming part sizes on an automated assembly line.
Heavy Load Positioning
Leverage the 14074N push force at 0.7 MPa to move heavy pallets or tooling bases, using the built-in air cushions to safely decelerate the mass at the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-10S the Right Cylinder?
Select this 160 mm bore actuator when an application demands high force alongside minor setup corrections, such as dialing in a 165 mm exact end-stop during machine commissioning. If your thrust requirements are lower, stepping down to a 125 mm bore yields 8590N push force at 0.5 MPa, whereas moving up to a 200 mm bore provides 21991N at 0.7 MPa. Because the nominal stroke is 170 mm, you avoid the side-load risks of long unsupported travel, though external guides are always recommended for heavy masses.
To match this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 160 mm bore, 170 mm nominal stroke, 10 mm adjustment range, PT port thread, and the integrated magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Choose this adjustable version over a fixed SAI model when product changeovers require variable end-stops rather than machining new hard stops.

- ✓ 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 SAIJ160X170-10S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 170 mm down to 160 mm. This creates a 160 to 170 mm usable window for fine-tuning the end position at commissioning, but it functions as a stop and does not lock the load without continuous air pressure.
