About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100
The AirTAC SAIJ160X145-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy machinery. By integrating a 100mm adjustment mechanism at the retract end, this unit allows the effective travel to be dialed back from its 145mm nominal stroke down to a 45mm minimum. This creates a highly flexible 45-145mm usable travel window, enabling precise end-position tuning during commissioning without swapping out the entire cylinder.
Featuring a robust 40mm carbon steel piston rod and a G3/4 PT port, this bore size generates 14095N of push force at 0.9 MPa. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It utilizes a reduced mounting interface subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets to streamline the adjustable assembly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100 Is Used
Heavy Press Tuning
Dial in the exact 45-145mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Rapidly adjust the retract end-position by up to 100mm on automated lines when switching to a new product size, minimizing downtime.
Assembly Station Setup
Fine-tune the end-of-stroke contact force on heavy assembly stations by trimming the effective stroke rather than repositioning the entire cylinder mount.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100 the Right Cylinder?
Choose this 160mm bore when substantial force is required, delivering 14095N of push at 0.9 MPa, or step down to a 125mm bore that provides 11045N if energy consumption is a higher priority. The 100mm adjustment range is specifically valuable in machine setups where product changeovers require shifting the end-stop position by tens of millimeters, replacing the need to manually bolt on external physical stops.
Because the 145mm stroke exceeds the 300mm threshold requiring external guides, side-load is less of a concern here, though the 40mm rod thread provides excellent rigidity. For exact ISO 15552 replacement matching, verify the 160mm bore, 145mm stroke, 100mm adjustment, G3/4 PT port, and your required mounting bracket. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ160X145-100 FAQ
The rear adjuster acts as an external stopper that trims the effective stroke. For this model, the nominal 145mm stroke can be shortened by up to 100mm, providing a usable travel window of 45-145mm for precise end-position calibration.
At 0.9 MPa operating pressure, the 160mm bore generates 14095N of push force and 18095N at 1.0 MPa. The operating speed for this size is rated between 30-500 mm/s.
