This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-50FTC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-50FTC 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 SIJ80X100-50FTC
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50FTC 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 drop-in replacement is the SAIJ80X100-50FTC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50FTC
The AirTAC SIJ80X100-50FTC is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 50-100 mm window from the 100 mm nominal maximum. It delivers 2513 N push and 2268 N pull at 0.5 MPa via its G3/8 port. The exact drop-in replacement is the SAIJ80X100-50FTC, matching the bore, force, adjust window, and FTC mount.
The SAIJ successor introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because this SKU lacks the -S suffix, it has no magnet and cannot accept a sensor. For sizing, the 2513 N @0.5 MPa push yields a safe working load of roughly 1508 N, or about 128 kg for a vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X100-50FTC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X100-50FTC produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50FTC Is Used
Press Fit Tuning
Trimming the extend stroke by up to 50 mm on-site allows precise positioning of press-fit pins without machining custom spacers.
Divertor Adjustment
Field-tuning the 100 mm extend stop lets operators alter the divertor reach on the line to accommodate varying package widths.
Pallet Stop Positioning
The external stop screw provides a rigid end position for pallets, allowing 50 mm of travel adjustment to adapt to different pallet heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50FTC with the SAIJ80X100-50FTC
To replace the discontinued SIJ80X100-50FTC, order the drop-in SAIJ80X100-50FTC to reuse the existing ISO 15552 interface and FTC mounting. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 50 mm adjust window if your end-position tuning requires trimming the 100 mm extend stroke down to a 50 mm minimum. This non-magnetic SKU cannot take a switch; add the -S suffix on the SAIJ order if you need legacy CS1-B/DS1-B sensor accuracy. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-50FTC
- ✓ 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 SIJ80X100-50FTC FAQ
Yes, the SIJ80X100-50FTC is discontinued. The exact drop-in replacement is the SAIJ80X100-50FTC, which shares the same ISO 15552 interface, 80 mm bore, 100 mm stroke, 50 mm adjust window, G3/8 port, and FTC mount. The SAIJ family also adds an upgraded piston seal and SAIL/BSAI lock variants.
