This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-50S 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X900-50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X900-50S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ200X900-50S is a discontinued double-acting single-rod adjustable-stroke ISO 15552 cylinder. A 50mm external stop screw lets you trim the extend stroke on-site, giving a usable 850-900mm stroke from the 900mm nominal maximum. This 200mm bore delivers 15708N push and 15080N pull at 0.5MPa, features a G3/4 port, and includes a 50mm adjustable air cushion at each end. The exact drop-in replacement is the SAIJ200X900-50S, sharing the same interface, force, and mounting.
The SAIJ upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For sizing, the safe working load is roughly 9425N (60% of the 0.5MPa push), yielding an 801kg vertical lift capacity with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that the external stop sets the end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant. At 900mm, external guides are advised to prevent rod bending.

The SAIJ200X900-50S 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).
Allows field adjustment of the extend stroke by up to 50mm to fine-tune heavy pressing operations without changing the cylinder body.
Provides a 850-900mm extend stroke for large material positioning, letting operators dial in the exact end stop on-site for varying pallet sizes.
Ideal for long-reach assembly stations where the 200mm bore delivers 15708N push at 0.5MPa and the stop screw sets the precise 900mm maximum reach.
To replace the discontinued SIJ200X900-50S, order the drop-in SAIJ200X900-50S, which preserves the 200mm bore, 900mm stroke, 50mm adjust window, G3/4 port, and ISO 15552 mounting. You can size both ways: the 160mm neighbor yields 10053N push @0.5MPa, while the 200mm provides 15708N. The 50mm adjust window is chosen when you need to fine-tune the extend end position on-site by up to 50mm. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B sensors. Because the 900mm stroke exceeds 300mm, use external guides to mitigate side-load and rod-bending risks.
Replacement checklist
Yes, the SIJ200X900-50S is discontinued. The exact drop-in replacement is the SAIJ200X900-50S, which matches the ISO 15552 interface, 200mm bore, 900mm stroke, 50mm adjust window, G3/4 port, and mounting hardware.
The 200mm bore provides 15708N push and 15080N pull @0.5MPa, 21991N push @0.7MPa, 28274N push @0.9MPa, and a theoretical max of 3204 kgf @1.0MPa. The external stop screw window is 50mm, allowing you to trim the extend stroke from 900mm down to 850mm on-site. The stop sets end position and is not a load lock.
