This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X100-75, 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 SIJ63X100-75
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X100-75 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 SAIJ63X100-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-75
The AirTAC SIJ63X100-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. The external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 25-100mm extension.
The direct replacement is the SAIJ63X100-75, retaining the same interface, force, and mounting. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. Note this SKU lacks a -S magnet, so it cannot take a switch.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-75 Is Used
Variable Depth Drilling
A fixture requiring precise drill depth changes between batches uses the 75mm adjust window to set exact 25-100mm extensions on-site without swapping cylinders.
Adjustable Transfer Pusher
A packaging line handling varying box widths uses the external stop screw to tune the extend position dynamically for different product formats.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-75 with the SAIJ63X100-75
To replace the discontinued SIJ63X100-75, order the direct replacement SAIJ63X100-75, which preserves the 75mm adjust window and ISO 15552 mounting. Choose the 75mm adjust window if your end-position needs on-site variation from 25 to 100mm; remember the stop sets position but is not a load lock. Mounting options include FA, LB, and TC. For strokes over 300mm, verify side-load limits to prevent guide wear. This non-magnetic SKU cannot accept legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X100-75
- ✓ 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 SIJ63X100-75 FAQ
Yes, the SIJ63X100-75 is discontinued. The direct replacement is the SAIJ63X100-75. It offers the same ISO 15552 interface, 63mm bore, 100mm nominal stroke, 75mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The external stop screw allows you to trim the extend stroke by up to 75mm on-site, giving a usable extension of 25-100mm. The stop sets end position only; it is not a load lock, and a plain cylinder will drift on air loss. For held loads, use an external rod lock or the SAIL/BSAI variant.
