This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X1000-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X1000-50S 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 SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-50S
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1000mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ160X1000-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-50S
The AirTAC SIJ160X1000-50S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 950-1000 mm from the 1000 mm nominal maximum. The 160 mm bore (G3/4 port, M36x2 rod thread, 50 mm adjustable cushion) delivers 10053 N push and 9425 N pull at 0.5 MPa, reaching 18095 N at 0.9 MPa. The exact drop-in replacement is the SAIJ160X1000-50S, matching the interface, bore, stroke, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions for hardware reuse and upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: using the 0.5 MPa push figure, the safe working load is roughly 6032 N (about 60% of 10053 N), yielding a vertical lift capacity of approximately 512 kg with a 2:1 margin. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. Note that the external stop sets end position but is not a load lock; for held loads, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAIJ160X1000-50S 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 SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-50S Is Used
Heavy Press Tonnage
Applies up to 18095 N of extend force at 0.9 MPa for forming operations, using the 50 mm stop screw to fine-tune the bottom dead center without re-mounting the cylinder.
Bulk Pallet Positioning
Indexes heavy pallets along a conveyor, trimming the 1000 mm extend stroke by up to 50 mm on-site to accommodate varying pallet lengths and stop locations.
Large Door Actuation
Drives oversized industrial doors or gates where the exact closed position requires field adjustment, relying on the 50 mm window to dial in the seal compression.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-50S with the SAIJ160X1000-50S
To replace the discontinued SIJ160X1000-50S, order the drop-in SAIJ160X1000-50S, which preserves the G3/4 port, 50 mm adjust window, and 50 mm cushions. The 50 mm stop screw is ideal if your end-of-stroke position needs minor field tuning between 950 and 1000 mm. For sizing both ways: the neighbouring 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N push. Mounting options include Basic, FA, LB, and TC. Because the 1000 mm stroke is long, provide external guides to prevent rod bending and manage side loads. The -S magnet supports position sensing, though the SAIJ uses current AirTAC switches instead of legacy CS1-B/DS1-B. The stop screw only sets end position; it does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X1000-50S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
