This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X100-30S, 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 SIJ63X100-30S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X100-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X100-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-30S
The AirTAC SIJ63X100-30S 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 30 mm on-site, yielding a usable 70-100 mm extension from the 100 mm nominal maximum.
As this SIJ model is end-of-life, the direct replacement is the SAIJ63X100-30S, reusing the same ISO 15552 mounting interface, bore, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL variant for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-30S Is Used
Variable Pitch Forming
Allows operators to trim the 100 mm extend stroke by up to 30 mm on-site to accommodate different material thicknesses without changing the cylinder.
Adjustable Diverter Gate
Provides a 70 to 100 mm push stroke to route varying package sizes, fine-tuning the gate extension in the field for optimal alignment.
Tiered Carton Stacking
Delivers precise end-position tuning for stacking heights, using the external stop to shorten the extend stroke as needed for different pallet configurations.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-30S with the SAIJ63X100-30S
To replace the SIJ63X100-30S, order the direct replacement SAIJ63X100-30S, keeping the same -S magnet for CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). The 30 mm adjust window allows field tuning of the extend stroke from 70 to 100 mm. Mounting options include FA, LB, and TC brackets. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw sets end position and does not hold loads without live air.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X100-30S
- ✓ 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 SIJ63X100-30S FAQ
Yes, the SIJ63X100-30S is discontinued. The direct replacement is the SAIJ63X100-30S, which shares the same ISO 15552 interface, 63 mm bore, 100 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ family also adds an upgraded piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable 70-100 mm stroke. The stop sets end position only and is not a load lock.
