About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-50
The AirTAC SAIJ160X650-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 600 to 650 mm. Built with a robust 40 mm SUS304 stainless steel rod and a M36x2 thread, it delivers substantial thrust, pushing 18095 N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides, although this specific SKU is configured without a magnet.
This heavy-duty actuator utilizes PT tapered port threads and includes variable air cushions at both ends to manage deceleration over the long stroke. The rear stopper mechanism allows technicians to dial in the exact end position during commissioning without adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-50 Is Used
Heavy Press Tuning
Dial in the exact 600-650 mm end position for large pressing operations without swapping actuators.
Product Changeover
Quickly adjust the stroke window during line changeovers to accommodate different large assembly dimensions.
Automated Heavy Material Handling
Shift large components precisely using the 18095 N thrust capacity with variable end-stop positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-50 the Right Cylinder?
Select this 160 mm bore when an application requires moving heavy loads within the 10053 to 18095 N push force range, stepping up from a 125 mm bore that provides 11045 N at 0.9 MPa. The adjustable 600-650 mm travel window is ideal for machinery requiring precise end-position tuning during product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider an external rod lock or the SAIL pneumatic-lock variant.
Because the 650 mm stroke is substantial, the 40 mm SUS304 rod provides excellent rigidity, yet an external guide is still recommended to manage side loads and prevent rod deflection. This model is dimensionally interchangeable with ISO 15552 cylinders and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets.
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 SAIJ160BX650-50 FAQ
At 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N.
The rear adjuster allows you to shorten the effective travel from the nominal 650 mm down to 600 mm, providing a 50 mm tuning window for precise end-position calibration.
