This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X160-10S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X160-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S
The AirTAC SIJ125X160-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 150-160 mm window from the 160 mm nominal maximum.
The direct replacement is the SAIJ125X160-10S, matching the interface, force, and mounting. The SAIJ family uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note the stop screw sets end position but is not a load lock; use SAIL or BSAI variants for held loads.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S Is Used
Press Fit Tuning
Trimming the final 10 mm of the extend stroke on-site to perfect the insertion depth of a bearing into a housing without re-engineering the entire fixture.
Divertor Gate Adjustment
Micro-adjusting the actuator end position to alter the trajectory of packages on a sorting line for varying product widths.
Sealing Head Calibration
Fine-tuning the extend stop to set precise contact pressure on a heat sealing jaw, accommodating different material thicknesses.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S with the SAIJ125X160-10S
To replace the discontinued SIJ125X160-10S, order the direct replacement SAIJ125X160-10S, retaining the same FA, LB, or TC mounts and the G1/2 port. Select the 10 mm adjust window if you need fine 150-160 mm extend tuning; for larger trims, pick a wider adjust model. The -S suffix provides a piston magnet for CS1-B/DS1-B sensors. For this 160 mm stroke, side-load is minimal, but for strokes >=300 mm, guide rails are recommended to prevent rod binding. The stop screw is for positioning only, not load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X160-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10S FAQ
Yes, the SIJ125X160-10S is discontinued. The direct replacement is the SAIJ125X160-10S, which shares the identical ISO 15552 interface, 160 mm stroke, 10 mm adjust window, G1/2 port, and mounting options. The SAIJ uses an upgraded piston seal for longer life.
This 125 mm bore cylinder features a 10 mm adjust window (usable extend stroke 150-160 mm). The external stop screw sets end position but is not a load lock.
