About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100S
The AirTAC SAIJ160X750-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a usable stroke window of 650 to 750 mm, which is highly useful for fine-tuning end positions during commissioning or product changeovers without swapping the cylinder or adding external stops. It delivers a robust thrust of 18095 N at 0.9 MPa.
This model incorporates an SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit reaches a maximum operating speed of 30-500 mm/s. The rear adjuster acts solely as a mechanical stop for deceleration and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100S Is Used
Variable End-Stop Tuning
Dial in the exact 650 to 750 mm travel distance during machine commissioning to accommodate varying product lengths without disassembling the pneumatic circuit.
Production Line Changeover
Rapidly adjust the retract end-position on packaging or sorting machinery when switching between different sized products, minimizing downtime.
High-Force Positioning
Leverage the 18095 N push force to move heavy assemblies into a precise final location, using the rear screw to set the exact hard stop distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires high force, specifically 18095 N of push force at 0.9 MPa. If your setup needs less force, stepping down to a 125 mm bore provides 11045 N at 0.9 MPa, while moving up to a 200 mm bore yields 28274 N. The adjustable stroke is selected over a fixed SAI model when you need variable end-stops to accommodate product-size changes on a line.
Because the stroke is 750 mm, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. For holding loads safely without live air pressure, the rear adjuster and air cushions are insufficient; you must integrate an external rod lock, a pilot-operated check valve, or use a related AirTAC type like the SAIL (air-released lock) or BSAI (clamp-lock). This SAIJ model uses a PT tapered port and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160AX750-100S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as an external mechanical stop that lets you shorten the nominal 750 mm stroke by up to 100 mm, providing a usable travel window of 650 to 750 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
