About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20
The AirTAC SAIJ160X195-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, offering 14074N push and 9425N pull at 0.7 MPa. By turning the external stopper screw at the rear, you can shorten the effective travel, creating a precise 175-195 mm usable stroke window without changing the cylinder body.
This 160 mm bore actuator features a robust 40 mm carbon steel rod and M36x2 thread, making it highly capable of handling heavy side loads. It uses PT tapered G3/4 ports and includes variable air cushions at both ends to absorb kinetic energy. The extruded aluminum barrel integrates dual sensor grooves, ready for CMSE reed or DMSE solid-state switches if a magnet is added later.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20 Is Used
Heavy Press Tuning
Dial in the 175-195 mm travel window during setup to accommodate varying material thicknesses in heavy-duty pressing operations.
Machine Changeover
Adjust the retract end-position on the fly when switching between product sizes, avoiding the need to swap out the entire cylinder.
Assembly Calibration
Fine-tune the end stop to perfect the seating force of large components without relying on external mechanical spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20 the Right Cylinder?
Choose this 160 mm bore when your application requires extreme force, stepping up from a 125 mm bore that provides 11045N push at 0.9 MPa. The adjustable stroke is ideal for heavy machinery commissioning, letting you dial in the exact 175-195 mm end position during product changeovers rather than machining external stops.
Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a locking device; it will not hold the load without live air. For positive load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 195 mm, ensure proper guiding for any heavy lateral loads.
Quick checklist
- ✓ 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 SAIJ160X195-20 FAQ
At 0.7 MPa, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
A stopper screw at the rear of the cylinder lets you mechanically shorten the retract stroke by up to 20 mm. This creates a usable travel window of 175 to 195 mm, allowing precise end-position tuning during installation.
