About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100
The AirTAC SAIJ160X250-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering heavy-duty performance for large-scale pneumatic setups. Featuring a 160 mm bore, it generates a substantial 18095 N of push force at 0.9 MPa. The integrated adjustment mechanism allows you to trim the 250 mm nominal stroke back by up to 100 mm, providing a flexible 150-250 mm usable travel window for precise end-position tuning during commissioning.
This unit is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered G3/4 ports. The extruded aluminum barrel includes sensor grooves on both sides for easy switch placement. It is important to note that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device; the cylinder cannot hold a load without live air pressure. For position-holding requirements, an external rod lock or a dedicated SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100 Is Used
Heavy Machinery Changeover
Dial in the 150-250 mm travel window during product family changeovers on large presses, eliminating the need to physically swap out heavy ISO 15552 cylinders.
Press Tonnage Setup
Leverage the 18095 N push force at 0.9 MPa for heavy stamping or clamping, using the rear stopper to fine-tune the exact bottom dead center position.
Large Material Handling
Actuate heavy lifting arms or diverter gates in high-capacity conveyors, relying on the SUS304 stainless steel rod to withstand harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100 the Right Cylinder?
Selecting this 160 mm bore model is ideal when your application demands high thrust, such as moving heavy pallets or actuating large forming presses, where a 125 mm bore (providing 11045 N push at 0.9 MPa) would be insufficient. The adjustable stroke is particularly valuable in machine setups requiring product changeovers, allowing operators to dial in the exact 150-250 mm travel distance without swapping out the entire cylinder or adding external mechanical stops. When replacing an ISO 15552 cylinder, match the 160 mm bore, 250 mm stroke, 100 mm adjustment range, PT G3/4 port thread, and your required mounting accessories.
Although the 250 mm stroke is relatively short for this bore size, the robust 40 mm rod and M36x2 thread provide excellent rigidity against side loads. For any application exceeding 300 mm of travel, an external guide rail is strongly recommended to prevent premature seal wear. The available mounting set for this series includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR configurations.

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 SAIJ160BX250-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 250 mm nominal stroke by up to 100 mm, creating a usable travel window of 150 to 250 mm. It only sets the end position and does not lock the load without air pressure.
