This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X60-30, 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 SIJ63X60-30
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X60-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X60-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-30
The AirTAC SIJ63X60-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63mm bore and 60mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 30 to 60mm window. The direct replacement is the SAIJ63X60-30, matching the interface, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch. The stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-30 Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 30mm on-site to push parts into fixtures of varying widths without swapping the entire cylinder.
Adjustable Transfer Diverter
Setting a precise 30 to 60mm extend position to deflect packages on a conveyor line, allowing field tweaks as product sizes change.
Custom Depth Stopping
Using the external stop screw to establish an exact end-stop for pallets or trays entering a machining cell, adjustable as pallet designs vary.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-30 with the SAIJ63X60-30
To replace the discontinued SIJ63X60-30, order the direct replacement SAIJ63X60-30, reusing your existing FA, LB, or TC ISO 15552 mounts. The 30mm adjust window lets you tune the extend end-position from 30 to 60mm on-site; the stop screw sets position but is not a lock, so for load-holding without live air specify SAIL or BSAI. This SKU lacks the -S magnet and cannot accept legacy CS1-B/DS1-B sensors. With a 60mm stroke, side-load is minimal, but for any stroke >=300mm ensure guide rails to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X60-30
- ✓ 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 SIJ63X60-30 FAQ
Yes, the SIJ63X60-30 is discontinued. The direct replacement is the SAIJ63X60-30. It shares the identical ISO 15552 interface, 63mm bore, 60mm stroke, 30mm adjust window, G3/8 port, and mounting options. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
This double-acting double-rod cylinder has a 30mm adjust window, allowing you to shorten the 60mm extend stroke down to 30mm on-site. The external stop screw sets the end position but is not a load lock.
