About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX95-20S
The AirTAC SAIJ160X95-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that fine-tunes the end position without adding external stops. It delivers a robust 14074N push force at 0.7 MPa, making it suited for heavy-duty positioning. The integrated -S magnet enables position feedback via CMSE reed or DMSE electronic sensors.
This specific SKU provides a usable travel window of 75 to 95 mm. It is built with an SUS420J2 stainless steel rod (option A) for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends absorb impact energy during high-load cycles.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX95-20S Is Used
Heavy Press Tuning
Dial in the exact 75-95 mm travel during heavy press commissioning to avoid crushing the workpiece, using the rear stopper instead of machining custom spacers.
Product Changeover
Quickly adjust the end-of-stroke position on a packaging line when switching between product sizes, maintaining the high 14074N thrust needed to secure heavy pallets.
Automated Assembly Stops
Set precise variable end stops for heavy automotive component placement, leveraging the 40 mm rod and SUS420J2 material to withstand harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX95-20S the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (5497N push at 0.7 MPa) lacks the thrust for your fixture, but a 200 mm bore (21991N) would be excessive. The 20 mm rear adjuster is ideal for product changeovers, letting you dial in the exact 75-95 mm travel on the machine without swapping the cylinder body. The 40 mm diameter carbon-steel-based piston rod handles high side loads well, but for any stroke exceeding 300 mm, an external guide is mandatory to prevent binding.
This cylinder uses a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pneumatic locking without pressure, 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 SAIJ160AX95-20S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 95 mm nominal stroke by up to 20 mm, providing a usable travel window of 75 to 95 mm. This stopper only sets the end position and decelerates the load via air cushions; it does not lock or hold the load without continuous air pressure.
