This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-20S in place of this model. 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 SIJ80X600-20S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-20S
The AirTAC SIJ80X600-20S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder featuring a 600 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable extend range of 580-600 mm. This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. The SIJ series is discontinued; the exact drop-in replacement is the SAIJ80X600-20S, retaining the same ISO 15552 mounting interface, bore, and force.
The SAIJ upgrade incorporates an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. Based on the 0.5 MPa push force, the computed safe working load is roughly 1508 N (60%), translating to a vertical lift capacity of about 128 kg with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that the external stop sets end position only; it is not a load lock, and a plain cylinder drifts on air loss.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-20S Is Used
Press Fit Tuning
Allows operators to fine-tune the extend stroke by up to 20 mm on-site, ensuring precise press-fit depths without changing the entire cylinder.
Transfer Diverter
Provides adjustable end-positioning for a diverter gate handling varying package sizes, allowing quick 580-600 mm stroke adjustments.
Pallet Stopper
Offers field-adjustable stopping points for pallets of different heights, trimming the extend stroke to meet exact positioning needs.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-20S with the SAIJ80X600-20S
To replace the discontinued SIJ80X600-20S, order the drop-in SAIJ80X600-20S, keeping the identical 80 mm bore, 600 mm stroke, 20 mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore provides 5497 N push at 0.7 MPa. Select the 20 mm adjust window if your field stroke tuning requires trimming the extend by up to 20 mm. Mounting options include Basic, FA, LB, and TC. The -S suffix confirms the piston magnet is present for switch sensing. Because the 600 mm stroke is long, verify external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-20S
- ✓ 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 SIJ80X600-20S FAQ
Yes, the SIJ80X600-20S is discontinued. The exact drop-in replacement is the SAIJ80X600-20S. It shares the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 20 mm adjust window, and G3/8 port, but features an upgraded piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The external stop screw provides a 20 mm adjust window, shortening the extend stroke from 600 mm down to 580 mm.
