About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30
The AirTAC SAIJ160X155-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 125 to 155 mm, allowing you to dial back the nominal 155 mm stroke by up to 30 mm during commissioning. Belonging to the 160 mm bore class, it outputs 10053 N of push force and 9425 N of pull force at 0.5 MPa.
This extruded aluminum barrel utilizes a PT tapered G3/4 port and a 40 mm carbon steel rod with an M36x2 thread. The rear stopper mechanism lets you fine-tune the end position without swapping out the entire cylinder. It includes variable air cushions at both ends and dual sensor grooves, operating at speeds between 30 and 500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30 Is Used
Press Tonnage Calibration
Dial in the exact 125 to 155 mm travel window during machine setup to calibrate press force without physically swapping out the actuator.
Product Size Changeover
Quickly adjust the rear stopper by up to 30 mm to accommodate varying product lengths on a high-thrust production line.
Heavy Material Forming
Leverage the 10053 N push force at 0.5 MPa for heavy-duty forming tasks while fine-tuning the retract end position on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30 the Right Cylinder?
Select this 160 mm bore model when your application requires substantial thrust, such as 10053 N at 0.5 MPa, and demands precise end-position tuning. If you need less force, stepping down to a 125 mm bore yields 6136 N of push at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, removing the need to bolt on external stops or buy a fixed-stroke SAI cylinder.
When ordering, confirm the 155 mm stroke, 30 mm adjustment range, PT G3/4 port, and carbon steel rod. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. Because the stroke exceeds 300 mm on larger variants, always use an external guide to support side loads.
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 SAIJ160X155-30 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that trims the effective travel. For this SAIJ160X155-30, you can shorten the 155 mm stroke down to as little as 125 mm. The adjuster sets the end position but does not lock the load without live air pressure.
