About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30
The AirTAC SAIJ160X375-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel window down to a 345-375 mm range. Delivering a substantial 14074 N of push force at 0.7 MPa, it is built for heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This SKU uses a robust 40 mm SUS304 stainless steel rod with an M36x2 thread, offering high corrosion resistance and excellent rigidity for demanding industrial environments. It features PT tapered ports and adjustable air cushions at both ends to manage heavy dynamic loads. The rear adjustment mechanism acts purely as a travel stop to fine-tune the end position during commissioning, and it does not function as a lock or brake to hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30 Is Used
Heavy Machinery Setup
Dial in the 345-375 mm retract end-stop precisely during large equipment commissioning without machining custom external spacers.
Product Size Changeover
Quickly adapt the stroke length on a packaging line when product dimensions change, using the 30 mm rear adjustment screw to shift the end position.
Press Positioning
Fine-tune the approach distance of a heavy press tooling by adjusting the travel window rather than re-mounting the entire ISO 15552 cylinder assembly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30 the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust beyond the 80 mm bore class (which provides 3518 N push at 0.7 MPa), but less than the massive 21991 N push of a 200 mm cylinder. The adjustable 30 mm travel window is ideal for product changeovers on large machinery, allowing you to fine-tune the retract end-position without swapping the cylinder or adding external stops. For fixed-travel applications without commissioning adjustments, the standard SAI cylinder is the simpler alternative.
Because the 375 mm stroke creates a long unsupported rod extension, an external guide is highly recommended to prevent excessive side-load wear on the piston seals. If your application requires true load-holding without continuous air pressure, this plain cylinder is insufficient; you should instead select an AirTAC SAIL pneumatic lock cylinder or a BSAI clamp-lock model. This SAIJ configuration features PT tapered ports and no internal magnet (-S omitted).

- ✓ 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 SAIJ160BX375-30 FAQ
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N, and at 0.9 MPa it reaches 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 375 mm nominal stroke by up to 30 mm, giving a usable travel window of 345-375 mm. It sets the deceleration end-position but does not lock or hold the load without live air pressure.
