This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X60-30S, 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 SIJ125X60-30S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X60-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X60-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X60-30S
The AirTAC SIJ125X60-30S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 125mm bore, 60mm nominal stroke, and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 30-60mm stroke window. This SIJ model is discontinued; the direct replacement is the SAIJ125X60-30S, sharing the same interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting footprint for direct hardware reuse and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X60-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 30-60mm extend position for inserting bearings without machining hard stops.
Diverter Gate Adjustment
Fine-tunes the extend stroke on-site to alter the deflection angle of packages moving at 30-500mm/s.
Pallet Stop Positioning
Trims the extend stroke by up to 30mm to adapt to varying pallet widths on the fly.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X60-30S with the SAIJ125X60-30S
To replace the discontinued SIJ125X60-30S, order the direct replacement SAIJ125X60-30S, keeping the same 125mm bore, 60mm nominal stroke, 30mm adjust window, G1/2 port, and ISO 15552 mounting. Choose the 30mm adjust window if your end-position needs field tuning between 30mm and 60mm. Mounting options include Basic, FA, LB, and TC. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAIJ replacement uses current AirTAC switches. For strokes at or above 300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X60-30S
- ✓ 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 SIJ125X60-30S FAQ
Yes, the SIJ125X60-30S is discontinued. The direct replacement is the SAIJ125X60-30S, offering the same ISO 15552 interface, 125mm bore, 60mm stroke, 30mm adjust window, G1/2 port, and mounting options.
The external stop screw shortens the 60mm extend stroke by up to 30mm on-site, yielding a 30-60mm usable window. The stop sets end position only; it is not a load lock.
