This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-30S, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X160-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S
The AirTAC SIJ80X160-30S 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 30 mm on-site, giving a usable 130-160 mm window from the 160 mm nominal maximum. It features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. The direct replacement is the SAIJ80X160-30S, sharing the same interface, force, and mounting.
The stop sets end position but is not a load lock; use SAIL or BSAI for held loads. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S Is Used
Variable Depth Forming
Adjusting the extend stroke on-site by up to 30 mm allows a single 80 mm bore cylinder to press parts of varying heights without changing the entire actuator setup.
Adjustable Transfer Stops
Trimming the extend stroke from 160 mm down to 130 mm accommodates different package sizes on a sorting line, providing flexible physical stopping points.
Tiered Pallet Positioning
Fine-tuning the end position by 30 mm on-site lets a lift mechanism settle pallets into distinct rack tiers without requiring multiple fixed-stroke cylinders.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S with the SAIJ80X160-30S
To replace the discontinued SIJ80X160-30S, order the direct replacement SAIJ80X160-30S, reusing your FA, LB, or TC ISO 15552 mounts. Choose the 30 mm adjust window when you need on-site extend trimming between 130-160 mm. The -S magnet supports legacy CS1-B/DS1-B sensors (current AirTAC switches on the SAIJ). For strokes >=300 mm, verify side-load guide tolerance. Remember the stop screw sets end position and does not lock; for load holding without live air, specify an external rod lock or SAIL variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-30S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30S FAQ
Yes, the SIJ80X160-30S is discontinued. The direct replacement is the SAIJ80X160-30S. It shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 30 mm adjust window, G3/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The external stop screw window is 30 mm, allowing the extend stroke to be shortened from the 160 mm maximum down to 130 mm on-site. The stop sets end position and is not a load lock.
