About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100
The AirTAC SAIJ160X300-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel. With a 300 mm nominal stroke and a 100 mm adjustment range, it provides a wide 200-300 mm usable travel window for highly flexible end-position tuning at commissioning. It delivers a robust 14074 N push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
This model uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to set the retract end-position without requiring external stoppers, but it does not lock the load without live air pressure. For load-holding without continuous air supply, an external rod lock or the SAIL series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100 Is Used
Variable Product Forming
Dial in the exact forming depth between 200 and 300 mm during product changeovers without physically replacing the actuator.
Heavy Fixture Clamping
Provides 14074 N of push force at 0.7 MPa to secure large workpieces, with a rear stopper that fine-tunes the clamp retract distance.
Machine Commissioning
Perfect for setup phases where the exact end-of-stroke position is unknown, allowing 100 mm of live mechanical adjustment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100 the Right Cylinder?
Choose this 160 mm bore if your application requires high force, specifically needing 10053 N of pull force at 0.5 MPa. If your thrust requirements are lower, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa. The 100 mm adjustment range is ideal for machines processing varying product sizes, allowing you to dial in the exact end-stop on the fly rather than swapping out a fixed-stroke SAI cylinder. When matching ISO 15552 dimensions, specify the 300 mm stroke, 100 mm adjust, PT port thread, SUS304 rod, and no magnet.
Because this cylinder features a 300 mm stroke, the 40 mm diameter rod and M36x2 thread provide substantial support, but long unsupported strokes still generate side loads. An external guide rail is recommended to prevent premature seal wear. Standard speeds are 30-500 mm/s, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX300-100 FAQ
At 0.5 MPa, this double-acting cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 100 mm, creating a 200-300 mm usable travel window. It sets the end position but does not hold the load without live air pressure.
