This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-40S, 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 SIJ32X175-40S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X175-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40S
The AirTAC SIJ32X175-40S 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 40 mm on-site, giving a usable 135-175 mm range (175 mm is the maximum).
The direct replacement is the SAIJ32X175-40S, retaining the same interface, force, and mounting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40S Is Used
Diverter Gate Positioning
Needs field stroke tuning to dial in the exact 145 mm gate open position on-site, using the 40 mm adjust window to accommodate varying package sizes without remounting.
Light Transfer Pusher
Requires adjusting the extend stroke from the 175 mm maximum down to 135 mm to push lighter components accurately between conveyor lanes while avoiding overtravel.
Carton Sealing Head
Demands on-site stroke trimming to set the precise 160 mm closure depth for varying carton heights, relying on the external stop screw to set the end position.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40S with the SAIJ32X175-40S
To replace the discontinued SIJ32X175-40S, order the direct replacement SAIJ32X175-40S, keeping the 40 mm adjust window and -S magnet for CS1-B/DS1-B sensors. Reuse existing FA, LB, or TC ISO 15552 mounts. The external stop trims the extend stroke by up to 40 mm on-site but is not a lock; for load holding without live air, use an external rod lock or SAIL/BSAI variant. For this 175 mm stroke, verify side-load tolerance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-40S
- ✓ 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 SIJ32X175-40S FAQ
Yes, the SIJ32X175-40S is discontinued. The direct replacement is the SAIJ32X175-40S, offering the same ISO 15552 interface, 32 mm bore, 175 mm stroke, 40 mm adjust window, G1/8 port, and mounting. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 40 mm adjust window, shortening the extend stroke on-site from 175 mm down to 135 mm. The stop sets end position and is not a load lock.
