About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-20
The AirTAC SAIJ160X165-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a substantial 14074N push force at 0.7 MPa, utilizing a robust 40mm carbon steel rod and M36x2 thread. The built-in rear stopper allows you to fine-tune the effective travel within a 145-165 mm window, providing exact end-position control without adding external stops.
This model features a PT tapered G3/4 port and variable air cushions at both ends to manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides for installing CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-20 Is Used
Press Tonnage Calibration
Dial in the exact 145-165mm end position during press setup to accommodate varying material thicknesses without swapping cylinders.
Assembly Line Changeover
Rapidly adjust the retract distance up to 20mm when switching product variants on a heavy-duty assembly line.
Heavy Fixture Alignment
Fine-tune the stroke end to perfectly seat large automotive or industrial fixtures during initial machine commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-20 the Right Cylinder?
Choose this 160mm bore when a 100mm cylinder's 5497N at 0.7 MPa is insufficient, but you want to avoid stepping up to a 200mm bore. The 20mm adjustment is ideal for fine-tuning the retract end during commissioning or product changeover. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series. To match an ISO 15552 replacement, verify the 165mm stroke, 20mm adjustment, PT G3/4 port, and the specific mounting accessory.
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 SAIJ160X165-20 FAQ
At 0.7 MPa, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. It can deliver up to 18095N push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the nominal 165mm stroke by up to 20mm. This creates a usable travel window of 145-165mm for precise end-position tuning without replacing the cylinder.
