About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30S
The AirTAC SAIJ160X165-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 135 to 165 mm. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches mounted along the dual sensor grooves.
This adjustable-stroke design allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a mechanical stop to set the travel limit and relies on the variable air cushions for deceleration; it does not lock or hold the load without live air pressure. The extruded aluminum barrel uses a G3/4 port and a robust 40 mm carbon steel rod with an M36x2 thread, handling high side loads while operating at speeds of 30 to 500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30S Is Used
Press Stroke Calibration
Dial in the exact 135 to 165 mm end-stop during machine commissioning to accommodate varying material thicknesses without changing the cylinder.
Heavy Forming Setup
Leverage the 14074 N push force at 0.7 MPa for heavy-duty forming operations, using the rear screw to fine-tune the bottom dead center.
Product Changeover
Quickly adjust the retract position on automated lines during product size transitions, utilizing the -S magnet for DMSE electronic sensor feedback.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30S the Right Cylinder?
Selecting the SAIJ160X165-30-S is ideal when an application requires exact end-position tuning within a 135 to 165 mm window, avoiding the need to stock multiple fixed-stroke SAI cylinders. If the 10053 N push force at 0.5 MPa from this 160 mm bore is insufficient, stepping up to the 200 mm bore yields 15708 N at the same pressure. Conversely, lighter setups might use the 125 mm bore, which provides 6136 N at 0.5 MPa.
For load-holding without continuous live air, this cylinder is insufficient because the rear adjuster functions only as a travel stop, not a brake. In such cases, an external rod lock or a related AirTAC type like the SAIL (air-released lock) or BSAI (clamp-lock) is required. This model features PT tapered port threads, a carbon steel rod, and supports mountings from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ160X165-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It achieves a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster allows you to mechanically shorten the 165 mm nominal stroke by up to 30 mm, creating a usable travel window of 135 to 165 mm. This stopper sets the end position but does not hold the load without live air pressure.
