This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X100-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X100-30S 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 SIJ160X100-30S
The AirTAC Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-30S 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 SAIJ160X100-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-30S
The AirTAC SIJ160X100-30S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 160 mm bore and 100 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 70-100 mm. This large-bore model delivers 10053 N push and 9425 N pull at 0.5 MPa, features a 50 mm adjustable air cushion at each end, and uses a G3/4 port. The built-in piston magnet (-S) supports legacy CS1-B/DS1-B reed switches.
As the SIJ series is end-of-life, the exact drop-in replacement is the SAIJ160X100-30S, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 6032 N (60% of the 0.5 MPa push), translating to a vertical lift capacity of about 512 kg with a 2:1 margin. Note that the external stop sets end position only; it is not a load 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 SAIJ160X100-30S 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 SIJ160X100-30S Is Used
Heavy Press Fit Tuning
Allows operators to fine-tune the 70-100 mm extend stroke on-site for pressing bearings, accommodating material thickness variations without changing the cylinder.
Adjustable Lowering Stop
Provides a hard mechanical stop for lowering heavy platens, trimming the extend stroke by up to 30 mm to prevent over-travel in varying product heights.
Variable Position Clamping
Delivers 10053 N of clamping force at 0.5 MPa while permitting 30 mm of external stroke adjustment to secure parts of slightly different dimensions.
Replacing the Airtac SIJ160 Double Rod Adjustable Cylinder SIJ160X100-30S with the SAIJ160X100-30S
To replace the discontinued SIJ160X100-30S, order the drop-in SAIJ160X100-30S, which matches the 160 mm bore, 100 mm stroke, 30 mm adjust window, G3/4 port, and ISO 15552 mounting. 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. Choose the 30 mm adjust window if your application requires field tuning the extend stroke between 70 and 100 mm. Mounting attachments (FA, LB, TC) can be reused from the SIJ. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the 100 mm stroke is under 300 mm, side-load rod deflection is minimal. Remember that the stop screw sets end position but does not lock the load; for load holding without live air, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ160X100-30S
- ✓ 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 SIJ160X100-30S FAQ
Yes, the SIJ160X100-30S is discontinued. The exact drop-in replacement is the SAIJ160X100-30S, which shares the same ISO 15552 interface, 160 mm bore, 100 mm stroke, 30 mm adjust window, and G3/4 port. The SAIJ upgrade features an improved two Y-shaped one-way piston seal for longer life.
The 160 mm bore cylinder has a 30 mm adjust window (usable extend stroke 70-100 mm). Force ratings are: 10053 N push / 9425 N pull @0.5 MPa, 14074 N push @0.7 MPa, 18095 N push @0.9 MPa, and a theoretical max of 2050 kgf @1.0 MPa. The external stop sets end position but is not a load lock.
