About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50
The AirTAC SAIJ160X170-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers substantial thrust, providing 14074N of push force at 0.7MPa, making it suited for heavy-duty positioning. By turning the external rear screw, you can shorten the effective travel, creating a precise 120-170mm usable window for exact end-position tuning without swapping the cylinder.
This 160mm bore utilizes a robust 40mm carbon steel rod and a PT G3/4 port to handle high flow and heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Unlike fixed-stroke SAI models, this adjustable variant allows on-the-fly end-stop modifications during product changeovers. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50 Is Used
Heavy Press Tuning
Dial in the exact 120-170mm travel window during machine commissioning to accommodate varying material thicknesses without installing external mechanical stops.
Product Changeover Stops
Quickly adjust the rear stopper screw on the line to handle different package sizes, changing the effective stroke by up to 50mm on the fly.
Large Assembly Positioning
Leverage the 14074N push force at 0.7MPa to move heavy pallets, using the adjustable end-position to fine-tune the final resting spot for precise mating.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50 the Right Cylinder?
Select this 160mm bore when your application requires heavy force, as it yields 9425N of pull force at 0.5MPa. If your setup needs less push, stepping down to a 125mm bore provides 5734N of pull at 0.5MPa, whereas moving up to a 200mm bore offers 15080N of pull at 0.5MPa. The 50mm adjustment range is ideal for machinery requiring variable end-stops during commissioning rather than adding external physical stops.
When replacing an ISO 15552 cylinder, match the 160mm bore, 170mm nominal stroke, 50mm adjustment, PT G3/4 port, and the required mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 170mm, an external guide is recommended to manage side loads on the unsupported rod. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead, as this adjuster is not a brake.
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 SAIJ160X170-50 FAQ
At 0.7MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 13195N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 2050 kgf.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective travel back by up to 50mm. For a 170mm nominal stroke, this creates a usable travel window of 120-170mm, allowing precise end-position tuning at commissioning.
