This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X100-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X100-40S 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 SIJ160X100-40S
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-40S 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 SAIJ160X100-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-40S
The AirTAC SIJ160X100-40S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the drop-in SAIJ160X100-40S. It uses a 40 mm external stop screw to trim the extend stroke on-site, giving a usable extend range of 60-100 mm from the 100 mm nominal maximum. The stop sets the end position but is not a load lock. With a 160 mm bore, G3/4 port, and 50 mm adjustable cushion, it delivers 10053 N push and 9425 N pull at 0.5 MPa.
The SAIJ replacement retains the exact interface and force but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is ~6032 N (60% of the 0.5 MPa push), yielding a ~512 kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss; for held loads use SAIL/BSAI or an external rod lock.

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 SAIJ160X100-40S 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 SIJ160X100-40S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 40 mm on-site allows precise press-fit depth adjustment for large bearings without machining custom spacers.
Diversion Gate Stops
Adjusting the extend end position dynamically accommodates varying package sizes on a heavy-duty conveyor line using the 18095 N push force.
Pallet Positioning
Field-tuning the extend stroke ensures positive contact against pallets of varying widths, leveraging the 50 mm cushion to decelerate heavy loads.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-40S with the SAIJ160X100-40S
Replace the discontinued SIJ160X100-40S directly with the SAIJ160X100-40S, reusing your existing ISO 15552 FA, LB, or TC mounting hardware without machining changes. When sizing both ways, the 125 mm bore neighbor offers 6136 N push @0.5 MPa, while the 200 mm bore provides 15708 N. This 160 mm bore generates 14074 N @0.7 MPa. The 40 mm adjust window lets you fine-tune the extend stroke down to 60 mm on-site; choose it when a fixed SAI plus external stop would add cumbersome bracketry. The -S magnet supports legacy CS1-B/DS1-B sensors. Because the 100 mm stroke is under 300 mm, side-load rod deflection is minimal, but always verify guide alignment to protect the 40 mm rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X100-40S
- ✓ 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 SIJ160X100-40S FAQ
Yes, the SIJ160X100-40S is discontinued. The exact drop-in replacement is the SAIJ160X100-40S, offering the same ISO 15552 interface, 160 mm bore, 100 mm stroke, 40 mm adjust window, G3/4 port, and mounting options. The SAIJ upgrades the piston seal to a two Y-shaped one-way element for longer life.
It provides 10053 N push and 9425 N pull @0.5 MPa, 14074 N push @0.7 MPa, and 18095 N push @0.9 MPa, with a theoretical max of 2050 kgf @1.0 MPa. The external stop screw provides a 40 mm adjust window, allowing the extend stroke to be shortened on-site from the 100 mm maximum down to 60 mm. The stop sets end position and is not a load lock.
