About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-75
The AirTAC SAIJ160X165-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, generating 10053N of pull force and 14074N of push force at 0.7MPa. The integrated rear stopper provides a usable travel window of 90 to 165mm, allowing you to fine-tune the retract end position without swapping out the entire unit.
This model features a robust 40mm carbon steel piston rod with an M36x2 thread, paired with 50mm variable air cushions at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes dual sensor grooves, and because no magnet is specified, position detection would require external proximity sensors rather than internal CMSE or DMSE switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-75 Is Used
Press Tonnage Calibration
Dial the 90-165mm travel window to precisely set crush depth during stamping or forming line commissioning without disassembling the tooling.
Heavy Fixture Positioning
Adjust the retract stopper to accommodate new part heights on a machining fixture, using the 40mm rod to handle high side-load stresses.
Assembly Line Changeover
Rapidly tune the end-position during product size transitions, leveraging the 75mm adjustment range to avoid adding physical spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-75 the Right Cylinder?
Choose this 160mm bore when a 125mm bore (providing 5734N pull at 0.5MPa) is insufficient, but a 200mm bore (15080N pull at 0.5MPa) would be physically oversized. The 75mm adjustment range is ideal for product changeovers, letting you dial in the exact end-stop on the fly instead of machining external spacers. The PT tapered port threads and standard carbon steel rod match general industrial requirements.
Keep in mind the rear adjuster acts strictly as a travel stop, not a lock, meaning the cylinder cannot hold a load without live air pressure. For fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL or BSAI series. Since the 165mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is always recommended for heavy 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 SAIJ160X165-75 FAQ
At 0.5MPa, this 160mm bore cylinder provides 10053N of pull force and 14074N of push force. At the maximum operating pressure of 1.0MPa, it can deliver up to 2050 kgf.
The nominal stroke is 165mm, but the rear adjuster allows you to trim the travel back by up to 75mm. This creates an adjustable usable window of 90 to 165mm for precise end-position tuning.
