About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75S
The AirTAC SAIJ160X500-75-S is a double-acting ISO 15552 profile cylinder featuring a robust 160 mm bore and a 500 mm nominal stroke. A rear-mounted adjusting screw provides a 75 mm trim range, yielding a usable travel window of 425-500 mm. This built-in stopper allows you to dial in the exact retract end-position during commissioning without adding external physical stops. At 0.5 MPa, it generates 10053 N of pull force, making it suitable for moving heavy industrial loads.
This specific SKU incorporates an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on three sides for flexible switch mounting. Fluid must be filtered air, operating within a 0.15-1.0 MPa pressure range and a -20 to +70 C temperature environment.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75S Is Used
Heavy Press Tonnage Tuning
Dial in the exact 425-500 mm retract position during product changeovers without physically swapping out the ISO 15552 cylinder or re-engineering the machine stops.
Variable End-Stop Setup
Use the 75 mm rear adjustment screw to compensate for mechanical wear or slight material thickness variations on the line, ensuring precise bottom-dead-center positioning.
Large Assembly Line Actuation
Leverage the 10053 N pull force to shift heavy pallets or tooling bases, relying on the built-in stopper to set the exact resting distance for robotic pickup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust (10053 N pull at 0.5 MPa) but demands on-the-fly end-position adjustments. The 75 mm rear adjuster acts purely as a travel stop to fine-tune the retract distance; it does not lock or hold the load without continuous air pressure. If your machine requires true fail-safe load holding, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the adjuster.
Because this model features a long 500 mm stroke, the 40 mm diameter piston rod and M36x2 thread will experience amplified leverage forces under side-loading. For strokes of 500 mm or more, always guide the load externally to prevent rod bending and premature seal wear. This cylinder uses a PT tapered G3/4 port and supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

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 SAIJ160AX500-75S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke by up to 75 mm. This gives the 500 mm nominal stroke a usable travel window of 425-500 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
Operating at 0.5 MPa, the SAIJ160X500-75-S provides 10053 N of pull force and 14074 N of push force. The maximum operating pressure is 1.0 MPa.
