This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-100, 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 SIJ63X200-100
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X200-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100
The AirTAC SIJ63X200-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 100-200 mm extend range from the 200 mm nominal maximum. The 63 mm bore features a G3/8 port, M16x1.5 rod thread, and 30 mm adjustable cushions. As a direct, the SAIJ63X200-100 replacement retains the exact interface, port, and force ratings.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Choosing an SAIJ with a built-in stop screw beats welding external stops to a fixed SAI cylinder, saving engineering time. Note: this non-magnetic SKU cannot take a switch, and the stop screw sets end position—it is not a load lock. For held loads, use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100 Is Used
Variable Pitch Indexing
Parts feeding operations needing field stroke tuning to accommodate different product lengths without swapping the entire actuator.
Adjustable Reject Pusher
Diverter arms on packaging lines where the extend stop screw is fine-tuned on-site to vary the push distance for changing box sizes.
Multi-Height Pallet Stops
End-of-line pallet handling requiring precise extend position adjustments to interface safely with varying pallet stack heights.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100 with the SAIJ63X200-100
To replace the discontinued SIJ63X200-100, order the direct replacement SAIJ63X200-100, which preserves the 63 mm bore, 200 mm nominal stroke, 100 mm adjust window, and G3/8 port. The 100 mm adjust window is ideal if your exact extend length is unknown until commissioning. Mounting interfaces (FA, LB, TC) reuse existing ISO 15552 holes. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load guidance to prevent rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-100
- ✓ 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 SIJ63X200-100 FAQ
Yes, the SIJ63X200-100 is discontinued. The direct replacement is the SAIJ63X200-100. It shares the identical ISO 15552 mounting interface, 63 mm bore, 200 mm stroke, 100 mm adjust window, G3/8 port, and force ratings, ensuring a seamless swap.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened on-site from 200 mm down to 100 mm. The stop sets end position and is not a load lock.
