This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX60, 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.

The AirTAC SI80 Standard Air Cylinder SI80BX60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX60, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80BX60 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 60 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80BX60, which shares the exact ISO 15552 mounting interface, bore, stroke, output force, and porting for a seamless fixture swap.
This SKU features a SUS304 stainless steel rod for corrosion resistance but lacks a magnet, meaning it cannot accept position sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life.

The SAI80BX60 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Leverages the SUS304 rod for corrosion resistance while providing 2513 N of clamping thrust at 0.5 MPa in humid washdown environments.
Uses the 60 mm stroke to rapidly actuate diverters or gates, moving packages safely within the 1508 N working load limit.
Functions as a heavy-duty stopping mechanism on roller conveyors, benefiting from the robust 80 mm ISO 15552 profile barrel.
To replace the discontinued SI80BX60, order the SAI80BX60 and verify your ISO 15552 mounting interface, G3/8 port threads (PT/G/NPT), and accessory type (LB, FA, TC, etc.). Because this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to a magnet-equipped SAI80BX60S. When sizing, a 63 mm bore offers 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external pilot check valve or use the SAIL/BSAI lock variants for held loads. If exploring the SAI family, the SAIF variant integrates a 4M valve for bores up to 100 mm.
Replacement checklist
Yes, the SI80BX60 is discontinued. The direct replacement is the SAI80BX60. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 60 mm stroke, G3/8 port, and mounting interface to fit existing fixtures directly.
The 80 mm bore uses a G3/8 port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80BX60 replacement — usually within 7-8 hours.
