This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-100 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X80-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100
The AirTAC SIJ200X80-100 is a discontinued double-acting, single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw allows you to trim the extend stroke by up to 100 mm on-site, yielding a usable 0-80 mm extend stroke from the 80 mm nominal maximum. This 200 mm bore model delivers 15708 N push and 15080 N pull at 0.5 MPa, features a 50 mm adjustable air cushion at each end, and uses a fixed G3/4 port. Because this SKU lacks a -S magnet, it cannot accept a magnetic switch.
As the SIJ series is end-of-life, the exact drop-in replacement is the SAIJ200X80-100, retaining the same interface, bore, force, and mounting. The SAIJ family incorporates an upgraded piston seal utilizing two Y-shaped one-way elements for lower start-up pressure and longer life. Regarding load handling, the external stop screw sets the end position but is not a lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for held loads. Based on the 0.5 MPa push force, the safe working load is roughly 9425 N (60% of 15708 N), translating to a vertical lift capacity of about 801 kg with a 2:1 margin.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100 Is Used
Heavy Press Tonnage
Provides 28274 N push at 0.9 MPa for high-force forming operations, with the 100 mm adjust window allowing precise bottom-dead-center tuning without machining spacers.
Large Mold Handling
Positions heavy industrial molds where the exact closure dimension varies by part number; the external stop screw sets the safe extend limit on-site.
Platen Lowering
Controls the descent of heavy platens using the 50 mm adjustable cushion to decelerate the 40 mm rod safely, though an external rod lock is required if the platen must be held against gravity.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100 with the SAIJ200X80-100
To replace the discontinued SIJ200X80-100, order the SAIJ200X80-100 directly; it is a true drop-in swap preserving the ISO 15552 mounting dimensions, G3/4 port, and 100 mm adjust window. If resizing, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while a 200 mm bore provides 15708 N at 0.5 MPa and 21991 N at 0.7 MPa. Choose the 100 mm adjust window if your mechanism requires field tuning the extend stroke down from the 80 mm maximum. Mounting options include Basic, FA, LB, and TC. Note that for strokes of 300 mm or longer, careful side-load management is required. This non-magnetic SKU cannot support position sensing.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-100 FAQ
Yes, the SIJ200X80-100 is discontinued. The exact drop-in replacement is the SAIJ200X80-100, which matches the ISO 15552 interface, 200 mm bore, 80 mm stroke, 100 mm adjust window, and G3/4 port. The SAIJ family also adds an upgraded piston seal and lock variants like SAIL and BSAI.
The 200 mm bore provides 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a 3204 kgf theoretical max at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 100 mm on-site, but this stop only sets the end position and is not a load lock.
