This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-75S, 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 SIJ63X200-75S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75S 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 SAIJ63X200-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75S
The AirTAC SIJ63X200-75S 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 75 mm on-site, giving a usable forward range of 125-200 mm from the 200 mm nominal maximum. The direct replacement is the SAIJ63X200-75S, matching the interface, force, and mounting.
The SAIJ successor retains the upgraded SAI piston seal (two Y-shaped one-way elements for low start-up pressure and long life). The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches. The stop screw sets the end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75S Is Used
Variable-depth Forming Press
Dialing the extend stroke on-site by up to 75 mm allows operators to change material crimp depths without swapping the entire actuator.
Adjustable Package Diverter
Trimming the forward stroke from 200 mm down to 125 mm accommodates varying box widths on a packaging line without mechanical spacers.
Tiered Pallet Stopper
Field-tuning the stop position by up to 75 mm lets a single cylinder handle multiple pallet heights before locking the end position.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75S with the SAIJ63X200-75S
To replace the discontinued SIJ63X200-75S, order SAIJ63X200-75S (insert A after S), keeping the 63 mm bore, 200 mm stroke, 75 mm adjust window, G3/8 port, and -S magnet. Choose the 75 mm adjust window if your end-position tuning exceeds 50 mm. Mounting options include FA, LB, and TC. For strokes >=300 mm, verify side-load guidance to prevent rod binding. The -S magnet works with legacy CS1-B/DS1-B switches (current AirTAC switches on SAIJ).
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-75S
- ✓ 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 SIJ63X200-75S FAQ
Yes, the SIJ63X200-75S is discontinued. The direct replacement is the SAIJ63X200-75S. It shares the same ISO 15552 interface, 63 mm bore, 200 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, but adds an upgraded SAI piston seal.
The external stop screw offers a 75 mm adjust window, shortening the 200 mm nominal extend stroke down to 125 mm. The stop sets end position but does not lock the load.
