This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X100-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X100-20S 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 SIJ160 Double Rod Adjustable Cylinder SIJ160X100-20S
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-20S 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 SAIJ160X100-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-20S
The AirTAC SIJ160X100-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 160 mm bore and 100 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 80-100 mm extension. The stop screw strictly sets the end position; it is not a load lock, so loads will drift on air loss. The exact drop-in replacement is the SAIJ160X100-20S, retaining the same G3/4 port, M36x2 rod thread, and 50 mm adjustable cushions.
This 160 mm bore delivers 10053 N push and 9425 N pull at 0.5 MPa, peaking at 18095 N push at 0.9 MPa. The SAIJ upgrade features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For sizing, the safe working load is roughly 6032 N (60% of the 0.5 MPa push), and vertical lift capacity is about 512 kg with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.

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 SAIJ160X100-20S 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 SIJ160X100-20S Is Used
Press Tonnage Calibration
Needs field stroke tuning to precisely set the 80-100 mm extend position during press setup, preventing over-travel on varying workpiece heights.
Heavy Pallet Diverter
Requires on-site stroke trimming to adjust the diverter stop distance by up to 20 mm for different pallet widths on a 160 mm bore line.
Stacker Height Indexing
Demands adjustable end-position tuning to accommodate varying stack heights, using the external stop screw to set the exact extend limit.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-20S with the SAIJ160X100-20S
To replace the discontinued SIJ160X100-20S, order the drop-in SAIJ160X100-20S; it preserves the ISO 15552 mounting interface, 160 mm bore, 100 mm stroke, 20 mm adjust window, and G3/4 port. When sizing both ways, the neighboring 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N push at 0.5 MPa; this 160 mm bore provides 10053 N push at 0.5 MPa. Choose the 20 mm adjust window if your application requires field tuning the extend stroke between 80 and 100 mm. Mounting options include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For stroke lengths >=300 mm, verify side-load limits to prevent excessive guide wear. Because the stop screw is not a lock, use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X100-20S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-20S FAQ
Yes, the SIJ160X100-20S is discontinued. The exact drop-in replacement is the SAIJ160X100-20S. It shares the same ISO 15552 interface, 160 mm bore, 100 mm stroke, 20 mm adjust window, G3/4 port, and mounting options, but adds an upgraded piston seal.
The 160 mm bore provides 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and 18095 N push at 0.9 MPa. The external stop screw window is 20 mm, allowing you to trim the extend stroke from the 100 mm maximum down to 80 mm on-site. The stop sets end position only; it is not a load lock.
