This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X160-100, 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 SIJ125X160-100
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X160-100 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 SAIJ125X160-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-100
The AirTAC SIJ125X160-100 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 100 mm on-site, yielding a usable 60-160 mm extend out of the 160 mm nominal maximum. The direct replacement is the SAIJ125X160-100, matching the bore, stroke, force, and mounting.
The SAIJ successor retains the ISO 15552 interface but introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S) and cannot take a sensor; the stop screw sets end position but is not a load lock.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-100 Is Used
Press Fit Tuning
Allows operators to fine-tune the extend stroke on-site during press-fit assembly, trimming up to 100 mm to accommodate varying part heights without changing the cylinder.
Variable Depth Sealing
Ideal for packaging lines needing precise end-position adjustment for different carton depths, using the external stop to set the exact 60-160 mm extend length.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-100 with the SAIJ125X160-100
To replace the discontinued SIJ125X160-100, order the direct replacement SAIJ125X160-100, keeping the exact 160 mm stroke and 100 mm adjust window. Choose the 100 mm adjust window when you need on-site flexibility to shorten the extend stroke down to 60 mm; a fixed SAI cylinder with an external stop is preferable only if no stroke variance is ever required. Mounting interfaces (FA, LB, TC) reuse standard ISO 15552 dimensions. Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. Remember the stop screw is not a lock; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X160-100
- ✓ 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 SIJ125X160-100 FAQ
Yes, the SIJ125X160-100 is discontinued. The direct replacement is the SAIJ125X160-100. It shares the same ISO 15552 interface, 125 mm bore, 160 mm stroke, 100 mm adjust window, G1/2 port, and mounting options, but adds an upgraded piston seal.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 60 mm on-site. The stop sets end position and is not a load lock.
