This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X160-40, 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 SIJ32X160-40
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X160-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 160mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X160-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X160-40
The AirTAC SIJ32X160-40 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, yielding a usable 120-160 mm extension from the 160 mm nominal maximum. As a direct replacement, the SAIJ32X160-40 matches the interface, force, and mounting.
The SAIJ successor retains the exact specifications but incorporates an upgraded piston seal utilizing two Y-shaped one-way elements for lower start-up pressure and extended life. This plain non-magnetic SKU lacks a -S sensor groove and cannot accept a reed switch. Remember the stop screw sets the end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X160-40 Is Used
Adjustable End-Stop Forming
Dialing in the exact extend position for a light press or forming head. The 40 mm stop window allows on-site tuning of the 160 mm stroke without machining spacers.
Variable Length Diverters
Actuating a routing gate where product lengths vary. The external screw lets operators trim the extend stroke by up to 40 mm to accommodate different package sizes.
Custom Position Pushers
Pushing bins to staggered stop points on a gravity conveyor.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X160-40 with the SAIJ32X160-40
To replace the discontinued SIJ32X160-40, order the direct replacement SAIJ32X160-40, matching the 32 mm bore, 160 mm stroke, 40 mm adjust window, and G1/8 port. Choose the 40 mm adjust window if your field tuning requires trimming the extend stroke by up to 40 mm on-site. Mounting hardware (FA, LB, TC) reuses the ISO 15552 interface directly. Because this SKU lacks the -S suffix, it cannot accept legacy CS1-B/DS1-B sensors. For stroke lengths of 300 mm or greater, verify side-load limits to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X160-40
- ✓ 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 SIJ32X160-40 FAQ
Yes, the SIJ32X160-40 is discontinued. The direct replacement is the SAIJ32X160-40, which shares the identical ISO 15552 interface, 32 mm bore, 160 mm stroke, 40 mm adjust window, and G1/8 port.
The external stop screw allows you to shorten the extend stroke by up to 40 mm on-site, yielding a usable extension of 120-160 mm. The stop sets end position and is not a load lock.
