This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-50TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-50TC 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.

The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC 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 SAIJ80X100-50TC, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-50TC is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 100 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 50-100 mm window. The stop sets the end position; it is not a load lock. At 0.5 MPa this 80 mm bore delivers 2513 N push and 2268 N pull force, scaling to 3518 N at 0.7 MPa.
The exact drop-in replacement is the SAIJ80X100-50TC, retaining the same ISO 15552 interface, TC mounting, and force. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push), giving a 128 kg vertical lift capacity with a 2:1 margin. Note this SKU lacks a -S magnet and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X100-50TC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X100-50TC 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.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Trimming the extend stroke by up to 50 mm on-site allows precise positioning for pressing operations without machining custom spacers.
A TC-mounted diverter can be tuned between 50 and 100 mm to accommodate different package sizes on a sorting line.
External stop screw adjustment allows operators to change the extend end position for varying pallet depths quickly.
To replace the discontinued SIJ80X100-50TC, order the drop-in SAIJ80X100-50TC, which preserves the 80 mm bore, 100 mm stroke, 50 mm adjust window, G3/8 port, and TC mount. 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. Choose the 50 mm adjust window if your extend stroke needs on-site tuning between 50 and 100 mm. The TC mount provides a rear clevis interface. Because this SKU has no -S magnet, it cannot accept a sensor; for sensing use a -S model. For strokes >=300 mm, verify side-load limits to prevent rod binding. A plain cylinder does not hold loads on air loss; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
Yes, the SIJ80X100-50TC is discontinued. The exact drop-in replacement is the SAIJ80X100-50TC. It shares the identical ISO 15552 interface, 80 mm bore, 100 mm nominal stroke, 50 mm adjust window, G3/8 port, and TC mount, while adding an upgraded SAI piston seal.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa (max 513 kgf at 1.0 MPa). The external stop screw provides a 50 mm adjust window, allowing the 100 mm extend stroke to be shortened on-site down to 50 mm. The stop sets end position and is not a load lock.
