About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20
The AirTAC SAIJ160X600-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. By integrating an external adjusting screw at the rear, this model allows you to fine-tune the effective stroke within a precise 580-600 mm window without swapping out the entire unit.
This cylinder features a SUS420J2 stainless steel rod (material code A) for enhanced durability against moisture, paired with PT tapered port threads (G3/4) for a reliable pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of CMSE reed or DMSE electronic solid-state switches if position feedback is later required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20 Is Used
Heavy Press Tuning
Dial in the exact 580-600 mm end-stop during commissioning to accommodate varying material thicknesses in large-scale pressing operations.
Product Line Changeover
Quickly adjust the rear stroke screw to modify the travel window for different product sizes on a high-force assembly line without changing cylinders.
Long-Stroke Positioning
Utilize the 600 mm travel for extending heavy tooling carts, relying on the 40 mm rod to handle substantial loads when properly guided.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20 the Right Cylinder?
Selecting this 160 mm bore cylinder is appropriate when an application demands high force that exceeds the 5497N push capability of the 100 mm bore at 0.7 MPa. The adjustable 580-600 mm travel window is ideal for machine setups requiring exact end-position tuning during commissioning or product changeovers, eliminating the need to bolt on external stops. Because the stroke is 600 mm, an external guide mechanism is strongly recommended to prevent excessive side-loading on the 40 mm rod and its M36x2 thread.
When specifying a replacement, verify the 160 mm bore, 600 mm stroke, 20 mm adjustment range, PT G3/4 port, and the absence of a magnet. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ160AX600-20 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can achieve a maximum push force of 18095N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 600 mm down to 580 mm. This creates a 580-600 mm usable window for fine-tuning the end position without needing external stops.
