About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40S
The AirTAC SAIJ160X375-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 18095 N at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves.
This specific SKU provides a nominal 375 mm stroke that can be fine-tuned down by up to 40 mm, creating a usable travel window of 335-375 mm. It features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions without relying on tie-rods.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40S Is Used
Heavy Stamping Alignment
Dial in the exact 335-375 mm end position during heavy stamping setup to accommodate different die heights without adding external stopper blocks.
Large Product Diversion
Adjust the retract distance on the fly to divert varying sizes of heavy pallets or components on a conveyor line.
Machine Changeover
Quickly reconfigure the stroke window during production line format changes, reducing downtime for mechanical adjustments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial force—delivering 14074 N push at 0.7 MPa—that smaller bores cannot provide. The adjustable stroke is ideal for fine-tuning the retract end position during commissioning or product changeovers without swapping the cylinder. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop; you must integrate an external rod lock or explore AirTAC SAIL or BSAI series cylinders.
Because this model features a 375 mm stroke, the 40 mm SUS304 rod and M36x2 thread must endure significant side loads. Always pair it with an external guide to prevent rod bending and premature seal wear. To match this ISO 15552 interchangeable cylinder exactly, specify: 160 mm bore, 375 mm stroke, 40 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
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 SAIJ160BX375-40S FAQ
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.9 MPa, the push force increases to 18095 N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm from the 375 mm nominal length, providing a usable travel window of 335-375 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
