About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100S
The AirTAC SAIJ160X425-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 325 to 425 mm. It delivers substantial thrust, providing 14074N push force at 0.7 MPa and peaking at 18095N at 0.9 MPa. The barrel is extruded aluminum with sensor grooves on both sides, and this unit includes a magnet for position sensing.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear adjuster allows you to fine-tune the end position at commissioning or during product changeover without swapping the cylinder or adding external stops. Note that the adjuster acts as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 325-425 mm end position during heavy press commissioning without machining new external stoppers.
Product Size Changeover
Adjust the retract stop on packaging conveyors to handle different product lengths rapidly during line changeovers.
Variable End-Stop Assembly
Set precise variable end-stops for large robotic assembly cells requiring high 18095N push force and flexible travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (7068N push at 0.9 MPa) is insufficient and you need heavy thrust capacity. The adjustable 325-425 mm travel window is ideal for variable end-stops or machine setup changes, whereas a fixed SAI cylinder locks you to one exact dimension. Because the stroke is 425 mm, the 40 mm rod and M36x2 thread carry significant side-load capacity, but an external guide is still recommended for long unsupported strokes.
For load-holding without continuous live air, this cylinder is not a lock; the rear adjuster and air cushions only set travel ends. You would need an external rod lock or a related type like SAIL or BSAI for fail-safe holding. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2 (omitting FB, CA, CB, CR).
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 SAIJ160BX425-100S FAQ
At 0.9 MPa it provides 18095N of push force and 9425N of pull force. At 0.7 MPa it delivers 14074N push force.
The rear adjuster screw lets you trim the effective travel back by up to 100 mm from the 425 mm nominal stroke, creating a 325-425 mm usable window. It acts as a mechanical stop, not a lock.
