This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X800-10S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X800-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S
The AirTAC SIJ100X800-10S 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 10 mm on-site, giving a usable 790-800 mm stroke. The stop sets the end position and is not a load lock.
The direct replacement is the SAIJ100X800-10S, sharing the same interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. For 800 mm strokes, use external guides to prevent rod bending.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise depth calibration when pressing bearings into housings without machining hard stops.
Transfer Diversion
Field-tuning the extend end position lets operators fine-tune the pusher stroke to match varying product widths on a packaging conveyor line.
Pallet Positioning
Adjusting the final extend position by 10 mm accommodates slight pallet size variances, ensuring exact alignment before stretch wrapping.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S with the SAIJ100X800-10S
Replace the discontinued SIJ100X800-10S directly with the SAIJ100X800-10S (same 100 mm bore, 800 mm stroke, 10 mm adjust window, and G1/2 port). Choose the 10 mm adjust window if you only need micro-trimming of the extend end position. Mounting interfaces (FA, LB, TC) are reusable. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Because the 800 mm stroke exceeds 300 mm, add external guides to manage side-load and rod-bending. The stop screw is not a lock; for load holding, use SAIL or BSAI.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X800-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-10S FAQ
Yes, the SIJ100X800-10S is discontinued. The direct replacement is the SAIJ100X800-10S. It shares the same ISO 15552 interface, 100 mm bore, 800 mm stroke, 10 mm adjust window, and G1/2 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life and lower start-up pressure.
The external stop screw window is 10 mm, allowing you to shorten the 800 mm extend stroke down to 790 mm on-site. The stop sets end position and is not a load lock.
