This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X700-10S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X700-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X700-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ63X700-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the direct replacement SAIJ63X700-10S. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 690-700 mm stroke window (the 700 mm nominal is the maximum).
The SAIJ successor retains the ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

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).
Needs field stroke tuning to dial in a 690-700 mm press stroke for seating bearings without over-traveling.
Requires trimming the extend stroke by up to 10 mm on-site to align a 63 mm bore pusher with varying package widths.
Demands precise end-position setting via the external stop screw for a 700 mm travel adhesive dispensing head.
To replace the discontinued SIJ63X700-10S, order the direct replacement SAIJ63X700-10S, keeping the 63 mm bore, 700 mm stroke, 10 mm adjust window, and -S magnet for CS1-B/DS1-B switches. Choose the 10 mm adjust window for fine end-position tuning rather than large travel changes. Mounting options include FA, LB, and TC brackets. Because the 700 mm stroke is long, ensure external guides to prevent rod bending and side-load wear.
Replacement checklist
Yes, the SIJ63X700-10S is discontinued. The direct replacement is the SAIJ63X700-10S, sharing the same ISO 15552 interface, 63 mm bore, 700 mm stroke, 10 mm adjust window, and G3/8 port.
The external stop screw window is 10 mm, allowing an extend stroke of 690-700 mm.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ63X700-10S replacement — usually within 7-8 hours.
