About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10S
The AirTAC SAIJ160X125-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 115-125 mm from its 125 mm nominal stroke. Delivering massive thrust, it provides 14074 N of push force at 0.7 MPa and utilizes a robust 40 mm carbon steel rod with an M36x2 thread to handle high side loads. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This adjustable-stroke model is designed for heavy-duty applications requiring exact end-position tuning at commissioning without swapping the cylinder or adding external stops. It features PT tapered port threading (G3/8) and variable air cushions at both ends to decelerate massive loads smoothly. The rear adjuster acts strictly as a travel stop, not a lock, meaning it cannot hold the load without live air pressure. For true load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 115-125 mm end-stop during heavy press commissioning to perfect stroke depth without machining external stoppers.
Product Changeover
Quickly adjust the rear stopper to accommodate varying product sizes on a heavy-duty assembly line, saving setup time.
Large Clamp Positioning
Use the massive 14074 N push force at 0.7 MPa to secure heavy components, relying on the rear screw for precise travel limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10S the Right Cylinder?
Choose this 160 mm bore when you need immense force that smaller bores cannot provide, such as when stepping up from a 125 mm bore that delivers 8590 N at 0.7 MPa. The SAIJ160X125-10-S is ideal for heavy machinery where you need a variable end-stop to dial in the final position during machine setup or product changeover. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 125 mm, you do not need external guides for side-load support as you would with strokes over 300 mm. To replace an ISO 15552 cylinder, match the 160 mm bore, 125 mm stroke, 10 mm adjustment, PT G3/8 port, and -S magnet.
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 SAIJ160X125-10S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 125 mm nominal stroke by up to 10 mm, creating a usable travel window of 115-125 mm. It is a travel stop for end-position tuning, not a lock, and cannot hold the load without live air pressure.
