About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20
The AirTAC SAIJ160X105-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. It features a robust 40mm carbon steel piston rod and a PT tapered port thread. By integrating an external adjusting stopper at the rear, this cylinder allows you to fine-tune the end position during commissioning without swapping out the entire unit.
With a nominal stroke of 105mm and a 20mm adjustment range, the usable travel window spans 85-105mm. This built-in adjustability is ideal for product-size changeovers on a production line. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding an -S option enables compatibility with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20 Is Used
Heavy Press Tuning
Dial in the exact 85-105mm travel window during heavy press commissioning to accommodate material thickness variations without external stops.
Product Changeover
Quickly adjust the rear stopper for different product sizes on a high-force assembly line, reducing downtime between production runs.
Large Fixture Alignment
Fine-tune the end position of heavy clamping fixtures, utilizing the 40mm carbon steel rod to handle substantial mechanical loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20 the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high thrust, such as 10053N push at 0.5MPa, combined with precise end-position tuning. If you need less force, stepping down to a 125mm bore yields 6136N push force. The adjustable stroke is selected over a fixed SAI model when you need variable end-stops for machine setup without adding external stops. To replace an ISO 15552 cylinder, match the 160mm bore, 105mm stroke, 20mm adjustment, PT port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding 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 SAIJ160X105-20 FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20mm. This provides a usable travel window of 85-105mm, which can be fine-tuned during setup or product changeovers without replacing the cylinder.
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can deliver a maximum push force of 18095N at 0.9 MPa.
