About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30S
The AirTAC SAIJ160X145-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 115-145 mm, letting you dial back the 145 mm nominal stroke by up to 30 mm during commissioning. Built with a carbon steel rod and a -S magnet, it supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-sided barrel grooves.
This 160 mm bore model delivers immense thrust, pushing with 14074 N at 0.7 MPa and pulling with 9425 N. The rear adjuster functions purely as a travel stop for end-position tuning, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI locking variants.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30S Is Used
Machine Setup Tuning
Dial in the exact 115-145 mm travel end-point during initial commissioning to perfectly seat heavy components without machining custom spacers.
Product Changeover
Quickly adjust the retract stop on a packaging line to accommodate a new product size, leveraging the 14074 N force for heavy actuation.
Assembly Pressing
Fine-tune the end-of-stroke position for pressing operations, ensuring consistent results while relying on the 40 mm carbon steel rod for stability.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30S the Right Cylinder?
Choose this adjustable-stroke cylinder when an installation requires precise end-position tuning without adding external stops or swapping components. If your application needs less force, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa. The integrated PT tapered port and G3/4 thread interface ensure reliable pneumatic connections.
As a direct ISO 15552 dimensionally interchangeable replacement, verify your bore, stroke, 30 mm adjustment range, PT porting, and mounting style. The SAIJ series utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the stroke is under 300 mm, side-load stress is moderate, though the robust 40 mm rod handles standard loads effectively.
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 SAIJ160X145-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 145 mm nominal stroke by up to 30 mm, creating a usable travel window of 115-145 mm. It is a stop, not a lock, and requires live air to maintain position.
