About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-30
The AirTAC SAIJ160X100-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 70 and 100 mm. It delivers massive thrust, generating 18095 N of push force at 0.9 MPa, making it ideal for heavy-duty press operations. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
A defining trait of this adjustable-stroke variant is the external stopper at the rear, which sets the retract end-position without requiring external stops. The 40 mm carbon steel rod and M36x2 thread provide high rigidity, though long unsupported loads still need an external guide. 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 SAIJ160X100-30 Is Used
Heavy Press Tuning
Dial in the exact 70-100 mm travel during commissioning to set the precise end-stop for heavy pressing operations without adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper on the fly when switching product sizes on a line, accommodating varying material thicknesses without replacing the actuator.
Machine Setup
Use the variable end-stop to fine-tune the retract position during initial machine assembly, ensuring perfect alignment of heavy tooling under high force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-30 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires immense force—stepping down to a 125 mm bore drops the 0.5 MPa push force to 6136 N, whereas this SAIJ160X100-30 provides 10053 N at the same pressure. Choose the adjustable-stroke SAIJ over a fixed SAI when you need variable end-stops for machine setup or product changeovers without swapping the cylinder. Configuration includes a PT tapered port, standard carbon steel rod, and no magnet.
For holding a load securely without live air pressure, this cylinder is not a lock; you should point to the SAIL or BSAI series instead. The mounting set is reduced to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552.
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 SAIJ160X100-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. It reaches a maximum push force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a stopper that lets you shorten the nominal 100 mm stroke by up to 30 mm, providing a usable travel window of 70 to 100 mm. It sets the end-position but does not lock or hold the load without live air pressure.
