This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-20, 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 SIJ32X175-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20 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 SAIJ32X175-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20
The AirTAC SIJ32X175-20 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 155-175 mm range (175 mm is the maximum). The direct replacement is the SAIJ32X175-20, matching the interface, force, and mounting.
The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet, so it cannot take a switch. The stop screw sets end position only; it is not a lock, and loads will drift on air loss—use SAIL or an external rod lock for holding.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20 Is Used
Actuator Length Calibration
Trimming the extend stroke by up to 20 mm on-site to dial in exact end-of-stroke positioning for a machining fixture without machining hard stops.
Transfer Pusher Adjustment
Fine-tuning a 32 mm bore push-off stroke between 155 and 175 mm to accommodate varying product sizes on a packaging conveyor line.
Prototype Tooling Setup
Using the external stop screw to iteratively adjust the extend reach during prototype assembly stations before finalizing fixed stop positions.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20 with the SAIJ32X175-20
To replace the discontinued SIJ32X175-20, order the direct replacement SAIJ32X175-20, which retains the 32 mm bore, 175 mm max stroke, 20 mm adjust window, G1/8 port, and ISO 15552 mounting. Choose the 20 mm adjust window if you need on-site tuning between 155 and 175 mm. Reuse FA, LB, or TC mounts. Since this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding. The external stop sets end position but is not a load lock; for held loads, use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-20
- ✓ 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 SIJ32X175-20 FAQ
Yes, the AirTAC SIJ32X175-20 is discontinued. The direct replacement is the SAIJ32X175-20. It shares the same ISO 15552 interface, 32 mm bore, 175 mm max stroke, 20 mm adjust window, G1/8 port, and mounting options, but adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 20 mm adjustment window, allowing the extend stroke to be shortened from the 175 mm maximum down to 155 mm. The stop sets end position only and is not a load lock.
