This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-100 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-100 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 SAIJ80X100-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-100
The AirTAC SIJ80X100-100 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw allows you to trim the extend stroke by up to 100 mm on-site, giving a usable 0-100 mm extend window from the 100 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable air cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
The exact drop-in replacement is the SAIJ80X100-100, preserving the ISO 15552 mounting interface, force, and adjustability. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the 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; the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X100-100 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 SAIJ80X100-100 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 SIJ80X100-100 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 100 mm to alter part spacing without swapping cylinders between production runs.
Adjustable Transfer Pusher
Trims the extend stroke on-site to push varying carton widths onto a belt, using the 2513 N push force at 0.5 MPa.
Variable Depth Diverter
Provides a 0-100 mm extend window to sort items into different lane depths while maintaining ISO 15552 mounting.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-100 with the SAIJ80X100-100
To replace the discontinued SIJ80X100-100, map directly to the SAIJ80X100-100. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N, compared to this 80 mm bore's 2513 N. Choose the 100 mm adjust window if the full extend trim range is needed. Mounting reuses standard ISO 15552 FA, LB, or TC interfaces. Because this SKU has no -S suffix, it lacks a magnet and cannot accept legacy CS1-B/DS1-B sensors. For any stroke at or above 300 mm, verify side-load limits to prevent rod binding. The external stop sets the end position but does not lock the load; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-100 FAQ
Yes, the SIJ80X100-100 is discontinued. The exact drop-in replacement is the SAIJ80X100-100, which shares the same ISO 15552 interface, 80 mm bore, 100 mm nominal stroke, 100 mm adjust window, G3/8 port, and 4523 N push force at 0.9 MPa.
This double-acting single-rod cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa, pushing 3518 N at 0.7 MPa and 4523 N at 0.9 MPa (513 kgf max at 1.0 MPa). The external stop screw lets you trim the extend stroke by up to 100 mm on-site. The stop sets end position only; it is not a load lock.
