This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X100-50SFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X100-50SFA 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 SIJ160X100-50SFA
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-50SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ160X100-50SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-50SFA
The AirTAC SIJ160X100-50SFA 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 50mm on-site, giving a usable 50-100mm stroke from the 100mm nominal maximum. This 160mm bore delivers 10053N push and 9425N pull at 0.5MPa, scaling to 18095N push at 0.9MPa. It features a 40mm rod, M36x2 thread, 50mm adjustable cushions, and a G3/4 port. The exact drop-in replacement is the SAIJ160X100-50SFA, matching the interface, force, and mount.
The SAIJ successor retains the ratings but uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 6032N (60% of the 0.5MPa push), yielding a 512kg vertical lift capacity with a 2:1 margin. The stop screw sets the end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants. The -S magnet enables CS1-B/DS1-B sensors, and the FA mount is standard.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ160X100-50SFA carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ160X100-50SFA 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 SIJ160X100-50SFA Is Used
Press Fit Tuning
Allows on-site extend stroke adjustment up to 50mm to dial in precise press-fit depths for large bearings without machining custom spacers.
Heavy Diverter Stroke Trim
Adjusts the extend stop on-site to accommodate varying pallet widths on a 160mm bore diverter, ensuring exact contact without repositioning the cylinder.
Pallet Positioning End-Stop
Sets a precise mechanical end position for heavy pallet lifts, trimming the 100mm stroke by up to 50mm to adapt to varying load heights on the fly.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-50SFA with the SAIJ160X100-50SFA
To replace the discontinued SIJ160X100-50SFA, order the drop-in SAIJ160X100-50SFA, which keeps the identical 160mm bore, 100mm stroke, 50mm adjust window, G3/4 port, and FA mounting interface. When sizing both ways, the neighboring 125mm bore provides 6136N push at 0.5MPa, while the 200mm bore offers 15708N. Choose the 50mm adjust window when you need on-site extend trimming between 50 and 100mm. The -S suffix provides a piston magnet for position sensing, and the FA foot mounting allows ISO 15552 interchangeability. For strokes at or exceeding 300mm, carefully manage side loads to prevent excessive guide wear. Note that the stop screw only sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X100-50SFA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-50SFA FAQ
Yes, the SIJ160X100-50SFA is discontinued. The exact drop-in replacement is the SAIJ160X100-50SFA. It shares the same ISO 15552 interface, 160mm bore, 100mm nominal stroke, 50mm adjust window, G3/4 port, and FA mounting, but features an upgraded piston seal for longer life.
The 160mm bore provides 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, and 18095N push at 0.9MPa, with a theoretical max of 2050kgf at 1.0MPa. The external stop screw provides a 50mm adjustment window, allowing the extend stroke to be shortened from the 100mm maximum down to 50mm on-site. The stop sets end position only; it is not a load lock.
