This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X1000-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X1000-20S 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 SIJ160X1000-20S
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-20S 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 SAIJ160X1000-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-20S
The AirTAC SIJ160X1000-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 160mm bore and 1000mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 980-1000mm forward travel. The stop sets the end position; it is not a load lock. This bore delivers 10053N push and 9425N pull at 0.5MPa, features a 50mm adjustable cushion at each end, and uses a G3/4 port. The exact drop-in replacement is the SAIJ160X1000-20S, retaining the same interface, force, and mounting.
The SAIJ successor incorporates an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. For sizing, a safe working load is approximately 6032N (60% of the 0.5MPa push), translating to a vertical lift capacity of about 512kg with a 2:1 margin. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder drifts on air loss; for load holding, specify an external rod lock or the SAIL/BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ160X1000-20S 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 SAIJ160X1000-20S 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 SIJ160X1000-20S Is Used
Large Press Tolerance
Trimming the 1000mm extend stroke by up to 20mm on-site allows precise end-position calibration for heavy pressing operations without machining custom spacers.
Heavy Assembly Station
Providing 10053N of push force at 0.5MPa, this 160mm bore cylinder seats large components, with the adjustable stop screw fine-tuning the final 20mm of travel.
Bulk Material Forming
The 50mm adjustable cushions decelerate the substantial moving mass at the end of the 1000mm stroke, while the external stop dials in the exact forming depth.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X1000-20S with the SAIJ160X1000-20S
To replace the discontinued SIJ160X1000-20S, order the SAIJ160X1000-20S drop-in; it matches the 160mm bore, 1000mm stroke, 20mm adjust window, G3/4 port, and ISO 15552 mounting interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2). When sizing both ways, the neighboring 125mm bore yields 6136N push at 0.5MPa, while the 200mm bore yields 15708N. Choose the 20mm adjust window if you need minor on-site end-position tuning between 980mm and 1000mm. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the stroke is 1000mm, you must support the rod against side-load bending and use external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X1000-20S
- ✓ 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 SIJ160X1000-20S FAQ
Yes, the SIJ160X1000-20S is discontinued. The exact drop-in replacement is the SAIJ160X1000-20S. It shares the same ISO 15552 interface, 160mm bore, 1000mm stroke, 20mm adjust window, G3/4 port, and mounting options. The SAIJ family also 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 window is 20mm, allowing you to shorten the 1000mm extend stroke to a minimum of 980mm. The stop sets end position and is not a load lock; speed is 30-500mm/s.
