This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-50TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-50TC 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 SIJ80X150-50TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-50TC, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X150-50TC is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a TC mount. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 100-150 mm window from the 150 mm nominal maximum. It delivers 2513 N push and 2268 N pull at 0.5 MPa via its G3/8 port, with a 25 mm rod and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X150-50TC, matching the bore, force, adjust window, and mounting.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse of your TC brackets and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: using the 0.5 MPa push rating yields a safe working load of roughly 1508 N (about 60% of 2513 N), translating to a vertical lift capacity of approximately 128 kg with a 2:1 safety margin. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X150-50TC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X150-50TC 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).
Ideal for clamping stations where part heights vary, using the 50 mm adjust window to tune the extend stroke on-site without swapping cylinders.
Deployed as a transfer gate stop on conveyors, allowing operators to shorten the 150 mm extend by up to 50 mm to accommodate different package profiles.
Used in sorting diverters where the exact extend endpoint must be dialed in during commissioning to prevent downstream collisions.
To replace the discontinued SIJ80X150-50TC, order the drop-in SAIJ80X150-50TC, keeping the identical 80 mm bore, 150 mm stroke, 50 mm adjust window, and TC mounting interface. If 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. The 50 mm adjust window is ideal if your extend stroke needs on-site tuning between 100 and 150 mm. Because this SKU lacks the -S suffix, it has no magnet and cannot accept legacy CS1-B/DS1-B sensors; add sensing externally if required. For strokes at or above 300 mm, verify your side-load limits to prevent guide wear. Remember the external stop sets end position but does not hold the load on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
Yes, the SIJ80X150-50TC is discontinued. The exact drop-in replacement is the SAIJ80X150-50TC, which shares the identical ISO 15552 interface, 80 mm bore, 150 mm stroke, 50 mm adjust window, G3/8 port, and TC mounting. The SAIJ family also features an upgraded piston seal for longer life.
This double-acting single-rod cylinder delivers 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 provides a 50 mm adjust window, allowing you to shorten the 150 mm extend stroke down to 100 mm on-site. The stop sets end position only and is not a load lock.
