About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-50S
The AirTAC SAIJ160X375-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 10053N pull force at 0.5 MPa and incorporates a SUS304 stainless steel rod for superior corrosion resistance. The built-in magnet (-S) works seamlessly with CMSE reed and DMSE electronic sensors, while the PT tapered port threads guarantee a reliable, leak-free pneumatic connection.
This specific SKU provides a 325-375mm usable travel window, allowing you to dial back the 375mm nominal stroke by up to 50mm. The extruded aluminum barrel includes sensor grooves on both sides, and the SAIJ mounting set omits FB, CA, CB, and CR brackets, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options for versatile machine integration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-50S Is Used
Variable End Stops
Perfect for production lines running mixed product sizes, allowing operators to dial in the exact 325-375mm travel distance on the fly without changing out the entire cylinder assembly.
Heavy Pressing
Generates up to 18095N of push force at 0.9 MPa, making it ideal for heavy-duty pressing, riveting, or forming tasks that require precise end-position control.
Machine Changeover
Speeds up machine setup and format changeovers by letting technicians fine-tune the retract end position via the rear screw, eliminating the need to bolt on external physical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-50S the Right Cylinder?
Choose this 160mm bore when you need substantial thrust, such as stepping up from a 125mm bore that provides 6136N push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position at commissioning without swapping the cylinder or adding external stops. For any stroke at 375mm, an external guide is highly recommended to handle side loads on the 40mm rod.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. For pilot-operated load holding, consider the SAIL or BSAI series. To replace this exact unit, match the 160mm bore, 375mm stroke, 50mm adjustment, PT ports, 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 SAIJ160BX375-50S FAQ
The SAIJ160X375-50-S uses an external adjusting screw at the rear that acts as a stopper on the retract end. This allows you to shorten the effective stroke from its 375mm nominal length down to a minimum of 325mm, providing a 50mm tuning window without needing to replace the cylinder.
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 2050 kgf of push force.
