This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-40TC, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40TC
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X200-40TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40TC
The AirTAC SIJ80X200-40TC 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 40 mm on-site, giving a usable 160-200 mm window from the 200 mm nominal maximum. As this SIJ model is end-of-life, the direct replacement is the SAIJ80X200-40TC, retaining the same interface, force, and TC mount.
The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss. Upgrading to the SAIJ family brings an upgraded two-piece Y-shaped piston seal for lower start-up pressure. The SAI line also adds lock variants (SAIL, BSAI) and integrated valve (SAIF) options the SI series lacked. This non-magnetic SKU cannot take a sensor.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40TC Is Used
Variable Depth Forming Press
Dialing in the exact extend stop on-site is critical when stamping materials of inconsistent thickness, allowing the 40 mm window to tune the 200 mm stroke without re-mounting the actuator.
Adjustable Package Diverter
Sorting lines handling mixed carton heights require field stroke tuning; trimming the extend stroke prevents crushing smaller parcels while maintaining full reach for larger loads.
Tiered Pallet Positioning
Depositing goods onto varying pallet stack heights demands precise end-position adjustment, using the stop screw to shorten the extend stroke on-site for each tier configuration.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40TC with the SAIJ80X200-40TC
To replace the discontinued SIJ80X200-40TC, order the direct replacement SAIJ80X200-40TC, which preserves the 80 mm bore, 200 mm nominal stroke, 40 mm adjust window, G3/8 port, and TC center-mount interface. Choose the 40 mm adjust window if your end-position tuning falls within 160-200 mm; for larger trims, select a different adjust code. The TC mount provides a fixed rear clevis via the ISO 15552 mounting interface. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; add -S for legacy CS1-B/DS1-B sensor accuracy. For stroke lengths of 300 mm or more, verify side-load limits to prevent guide wear. Remember the stop screw is not a lock; for held loads use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-40TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
