This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-30S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X200-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S
The AirTAC SIJ80X200-30S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 170-200 mm. The stop sets the end position; it is not a load lock. Force output is the standard single-rod SAI rating: 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
This SIJ model is discontinued and the exact drop-in replacement is the SAIJ80X200-30S, sharing the same bore, stroke, adjust window, force, and mounting interface. The SAIJ family uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: at 0.5 MPa the safe working load is roughly 1508 N (60% of push), translating to a 128 kg vertical lift with a 2:1 margin. Note that a plain cylinder drifts on air loss; for load holding use SAIL, BSAI, or an external rod lock.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X200-30S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 170-200 mm extend position for seating bearings without machining hard stops.
Variable Transfer Diverter
Adjusts the extend endpoint on-site to deflect varying package sizes on a packaging line.
Adjustable End Stop Pusher
Provides a field-tunable end position for aligning pallets, accommodating different pallet depths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S with the SAIJ80X200-30S
To replace the discontinued SIJ80X200-30S, order the drop-in SAIJ80X200-30S, keeping the existing ISO 15552 FA, LB, or TC mounts and the G3/8 porting. When sizing both ways, the neighboring bores offer distinct force steps: the 63 mm bore provides 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 30 mm adjust window if your end-of-stroke position needs on-site tuning between 170 and 200 mm. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, carefully verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-30S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30S FAQ
Yes, the SIJ80X200-30S is discontinued. The exact drop-in replacement is the SAIJ80X200-30S. It shares the same ISO 15552 interface, 80 mm bore, 200 mm stroke, 30 mm adjust window, G3/8 port, and mounting, but uses an upgraded piston seal.
The double-acting single-rod force is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The external stop screw provides a 30 mm trim window, allowing the extend stroke to be shortened from 200 mm down to 170 mm on-site.
