This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X75-50, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X75-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50
The AirTAC SIJ32X75-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 25-75 mm extend window from the 75 mm nominal maximum.
The direct replacement is the SAIJ32X75-50, matching the interface, force, and mounting. The SAIJ line upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. Note this SKU has no magnet (-S) and cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50 Is Used
Short-Stroke Clamping
Tuning the extend stop on-site to clamp delicate castings precisely within a 25-75 mm window without re-plumbing the G1/8 air lines.
Variable Diverter Arm
Adjusting the extend stroke by up to 50 mm to deflect varying package sizes on a conveyor line, then locking the external screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50 with the SAIJ32X75-50
To replace the discontinued SIJ32X75-50, specify SAIJ32X75-50 to retain the exact 32 mm bore, 75 mm nominal stroke, 50 mm adjust window, and G1/8 port. The 50 mm adjust window is ideal if the final end position needs tuning between 25 and 75 mm. Mounting interfaces (FA, LB, TC) are reusable. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. The stop screw sets end position only; it is not a lock, so use SAIL/BSAI or an external rod lock for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X75-50
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-50 FAQ
Yes, the SIJ32X75-50 is discontinued. The direct replacement is the SAIJ32X75-50, which shares the identical ISO 15552 interface, 32 mm bore, 75 mm stroke, 50 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw provides a 50 mm adjust window, allowing the 75 mm nominal extend stroke to be shortened on-site down to 25 mm. The stop sets end position and is not a load lock.
