About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-50S
The AirTAC SAIJ160X165-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end position during commissioning. With a 165 mm nominal stroke and a 50 mm adjustment screw, it provides a usable travel window of 115 to 165 mm without requiring external stops. It features a standard carbon steel piston rod and a built-in magnet for CMSE and DMSE sensors.
In the 160 mm bore class, this cylinder delivers a 10053 N pull force and a 14074 N push force at 0.7 MPa. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the standard G3/4 interface. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits; it does not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-50S Is Used
Heavy Press Tonnage Setup
Dial in the exact 115-165 mm retract distance during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the end-stop on automated assembly lines when switching between different product dimensions, saving setup time.
Variable End-Stop Positioning
Use the rear adjuster to set precise deceleration points for heavy loads moving at up to 500 mm/s within the 160 mm bore class.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-50S the Right Cylinder?
Selecting this 160 mm bore over a smaller 125 mm unit upgrades your thrust from 5734 N to 10053 N pull force at 0.5 MPa, which is critical for heavy-duty positioning. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers. For load-holding without continuous air pressure, this plain cylinder is insufficient—consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. As an ISO 15552 interchangeable replacement, match the 160 mm bore, 165 mm stroke, 50 mm adjuster, PT G3/4 port, and -S magnet.
Although the 165 mm stroke is below the 300 mm threshold where external guides become mandatory, the 40 mm rod diameter and M36x2 thread provide substantial side-load resistance. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR footprints. Speeds range from 30 to 500 mm/s.

- ✓ 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 SAIJ160X165-50S FAQ
This 160 mm bore cylinder provides a push force of 14074 N and a pull force of 10053 N at 0.7 MPa, with a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 165 mm down to 115 mm, creating a 50 mm adjustable window for fine-tuning the end position during setup.
