This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X75-10S, 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.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X75-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S
The AirTAC SIJ63X75-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and a 75 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 65-75 mm window. The direct replacement is the SAIJ63X75-10S, sharing the same interface, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. The external stop sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S Is Used
Press Fit Tuning
Allows operators to dial in the exact 65-75 mm extend position for seating bearings without machining custom spacers.
Divertor Gate Adjustment
Provides on-site stroke trimming to fine-tune package deflection angles on a 63 mm bore actuator.
Pallet Stop Positioning
Sets a precise mechanical end-stop for varying pallet widths, using the 10 mm adjust screw to set the final resting point.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S with the SAIJ63X75-10S
To replace the discontinued SIJ63X75-10S, order the direct replacement SAIJ63X75-10S, which preserves the 63 mm bore, 75 mm stroke, 10 mm adjust window, G3/8 port, and ISO 15552 mounting. Choose the 10 mm adjust window if you need precise 65-75 mm end-position tuning. Mounting options include FA, LB, and TC brackets. The -S suffix confirms the piston magnet is present for legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, carefully verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X75-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X75-10S FAQ
Yes, the SIJ63X75-10S is discontinued. The direct replacement is the SAIJ63X75-10S, which shares the same ISO 15552 interface, 63 mm bore, 75 mm stroke, 10 mm adjust window, G3/8 port, and mounting.
The external stop screw allows trimming the extend stroke by up to 10 mm on-site (usable 65-75 mm). The stop sets end position and is not a load lock.
