This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X100-30SN, 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 SIJ80X100-30SN
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-30SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X100-30SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-30SN
The AirTAC SIJ80X100-30SL is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm nominal stroke and a 30 mm on-site extend-trim window, yielding a usable extend range of 70-100 mm. The external stop screw sets the end position but is not a load lock. The direct replacement is the SAIJ80X100-30SL.
The SAIJ successor reuses the same ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. A plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-30SN Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 30 mm on-site allows a 80 mm bore actuator to adapt drill depth precisely without changing the entire cylinder body.
Adjustable Diverter Stroke
An external stop screw shortens the extend stroke to accommodate changing package sizes on a conveyor line, providing flexible 70-100 mm routing.
Variable Height Stops
Field-tuning the extend end position lets a packaging cell adjust mechanical stops for different pallet heights quickly and reliably.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-30SN with the SAIJ80X100-30SN
Replace the discontinued SIJ80X100-30SL directly with the SAIJ80X100-30SL, retaining the G3/8 port, M20x1.5 rod thread, and 36 mm cushions. Choose the 30 mm adjust window if your extend stroke needs field tuning between 70 and 100 mm. Mounting options include FA, LB, and TC brackets. The -S magnet enables CS1-B/DS1-B sensors. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-30SN
- ✓ 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 SIJ80X100-30SN FAQ
Yes, the SIJ80X100-30SL is discontinued. The direct replacement is the SAIJ80X100-30SL, which matches the ISO 15552 interface, 80 mm bore, 100 mm stroke, 30 mm adjust window, and G3/8 port.
The 30 mm adjust window allows shortening the 100 mm extend stroke down to 70 mm on-site.
