About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-50
The AirTAC SAIJ160X50-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 14074N of push force at 0.7 MPa and features a robust 40mm piston rod. Because of the 50mm nominal stroke paired with a 50mm adjustment code, you gain a highly versatile 0-50mm usable travel window, allowing exact end-position tuning without swapping hardware.
This unit utilizes a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic sensors cannot be used without modification. The rear stopper sets the retraction limit but does not lock the load mechanically.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-50 Is Used
Heavy Press Tuning
Dial in the exact 0-50mm clamping depth on heavy metal-forming presses during initial commissioning without machining external stop blocks.
Product Changeover
Quickly adjust the retraction end-stop on packaging lines when switching between different product sizes or thicknesses.
Robotic End Effectors
Provide fine-tuned, high-force linear actuation for large robotic grippers requiring precise positioning of heavy payloads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-50 the Right Cylinder?
Select this 160mm bore cylinder when an application demands extreme force that a 125mm bore cannot provide, stepping up from 8590N to 14074N at 0.7 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, replacing the need for fixed-stroke SAI cylinders when exact positioning is unknown at commissioning. For load-holding without live air pressure, this adjuster acts only as a travel stop, so you must integrate an external rod lock or choose an AirTAC SAIL or BSAI cylinder.
To match this ISO 15552 interchangeable cylinder, confirm the 160mm bore, 50mm stroke, 50mm adjustment, PT G3/4 port, and the SUS304 rod material. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the nominal stroke is only 50mm, side-loading is minimal, but the heavy 40mm rod thread still requires proper alignment to prevent premature seal wear.
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 SAIJ160BX50-50 FAQ
At an operating pressure of 0.7 MPa, this 160mm bore cylinder generates 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw lets you trim the effective stroke anywhere within a 0-50mm window from the 50mm nominal stroke. It acts as a mechanical stop to set the end position, but it does not lock the load without continuous air pressure.
