This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-10 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 SIJ80X100-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-10
The AirTAC SIJ80X100-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 90-100 mm stroke out of the 100 mm nominal maximum. The 80 mm bore uses a G3/8 port, a 25 mm rod, and delivers 2513 N push and 2268 N pull at 0.5 MPa. AirTAC specifies the SAIJ80X100-10 as the exact drop-in replacement, retaining the same ISO 15552 mounting interface, force, and 10 mm adjust window.
For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets the end position but is not a load lock; the cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads. This SKU lacks a -S magnet and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X100-10 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 SAIJ80X100-10 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 SIJ80X100-10 Is Used
Press Fit Calibration
Trimming the extend stroke by up to 10 mm on-site allows operators to dial in the exact 90-100 mm insertion depth for light press-fit operations without changing the cylinder body.
Transfer Diverter Setup
Field-tuning the 80 mm bore extend endpoint ensures a diverter gate meets varying product profiles precisely, leveraging the 2513 N push force at 0.5 MPa.
Pallet Stop Positioning
Adjusting the external stop screw sets the final 90-100 mm stopping position for pallets on a line, accommodating different pallet lengths using the same ISO 15552 mount.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-10 with the SAIJ80X100-10
To replace the discontinued SIJ80X100-10, order the SAIJ80X100-10 drop-in; it keeps the 80 mm bore, 100 mm max stroke, 10 mm adjust window, and G3/8 port. For sizing both ways, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push at 0.5 MPa. Choose the 10 mm adjust window when you need precise 90-100 mm extend endpoint tuning without machining. Mounting reuses ISO 15552 FA, LB, or TC attachments. Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes at or over 300 mm, verify side-load guide tolerances to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-10
- ✓ 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 SIJ80X100-10 FAQ
Yes, the SIJ80X100-10 is discontinued. The exact drop-in replacement is the SAIJ80X100-10. It shares the same 80 mm bore, 100 mm nominal stroke, 10 mm adjust window, G3/8 port, and ISO 15552 mounting interface. The SAIJ family also adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The 80 mm bore provides 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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 10 mm on-site, yielding a usable 90-100 mm stroke. The stop sets end position only; it is not a load lock, and the cylinder drifts on air loss.
