This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-10 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 SIJ80X175-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X175-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10
The AirTAC SIJ80X175-10 is a discontinued double-acting single-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 165-175 mm stroke out of the 175 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable air cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa.
The exact drop-in replacement is the SAIJ80X175-10, matching the ISO 15552 mounting interface, bore, and force. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. Note: this SKU lacks a -S magnet and cannot take a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X175-10 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ80X175-10 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 SIJ80X175-10 Is Used
Press Fit Calibration
Fine-tune the extend stroke by up to 10 mm on-site to dial in exact press-fit depths for bearings without machining custom spacers.
Transfer Stopper Adjustment
Trim the extend position to accommodate varying product sizes on a packaging line, using the external stop to set the precise end location.
Pallet Positioning Gate
Adjust the extend stroke within the 165-175 mm window to perfectly align pallet stops when floor tolerances fluctuate slightly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10 with the SAIJ80X175-10
To replace the discontinued SIJ80X175-10, order the drop-in SAIJ80X175-10, which preserves the G3/8 port, 175 mm nominal stroke, and 10 mm adjust window. When sizing both ways, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Select the 10 mm adjust window if you only need micro-trimming of the end position. Reuse FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw sets end position but is not a load lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-10
- ✓ 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 SIJ80X175-10 FAQ
Yes, the SIJ80X175-10 is discontinued. The exact drop-in replacement is the SAIJ80X175-10. It shares the identical ISO 15552 interface, 80 mm bore, 175 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but adds an upgraded SAI piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing the extend stroke to be shortened from 175 mm down to 165 mm.
