About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-50
The AirTAC SAIJ160X105-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 55 to 105 mm, allowing you to dial back the 105 mm nominal stroke by up to 50 mm during commissioning. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 14074 N pull force at 0.7 MPa.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster functions purely as a travel stop, meaning it will not hold the load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL or BSAI series.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-50 Is Used
Variable End-Stop Tuning
Dial in the exact 55 to 105 mm travel distance during machine commissioning without replacing the cylinder or adding external mechanical stops.
Product Size Changeover
Quickly adapt the retract stroke on a production line to accommodate different product sizes, reducing setup time between batches.
Precision Positioning
Use the 50 mm adjustment range to fine-tune the end position of heavy loads, leveraging the 14074 N pull force at 0.7 MPa for robust actuation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-50 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match. When ordering, confirm the 160 mm bore, 105 mm stroke, 50 mm adjustment, PT ports, and SUS304 rod material. Because the stroke is over 300 mm? No, but for any stroke over 300 mm, always ensure external guidance to manage side loads.
Mounting options for this SAIJ model include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles. The cylinder operates at speeds of 30-500 mm/s. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not act as a lock. For true position holding without live air, explore the SAIL (air-released lock) or BSAI (clamp-lock) cylinders, or use an external pilot-operated check valve.
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 SAIJ160BX105-50 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 55 to 105 mm, which can be fine-tuned during commissioning without changing the cylinder.
At 0.9 MPa, the push force increases to 18095 N.
