This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX200SH, 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 SI80BX200SH 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 SAI80BX200SH, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80BX200SH is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 200mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80BX200SH, matching the interface, bore, stroke, force, and mounting exactly.
This unit features a SUS304 stainless steel rod (-B) and a Viton H seal (-H) for 0-150 C high-temperature environments. The SAI upgrade utilizes two Y-shaped one-way piston seals for low start-up pressure. The -S magnet works with legacy CS1-B/DS1-B sensors.

The SAI80BX200SH 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).
Ideal for pressurizing molds or actuating clamps near ovens, utilizing the Viton H seal to withstand 0-150 C ambient heat without degrading.
The SUS304 stainless piston rod provides splash resistance for automated rinsing stations where carbon steel would pit and fail.
Generates 2513 N of push force at 0.5 MPa to reliably deflect heavy pallets or metal billets on high-throughput material lines.
To replace the SI80BX200SH, order the SAI80BX200SH to retain the identical ISO 15552 mounting dimensions, 80mm bore, 200mm stroke, G3/8 port, and M20x1.5 rod thread. Confirm your mounting accessory (LB, FA, TC, etc.) and the magnet (-S) for current AirTAC switch compatibility. Sizing both ways: the 80mm bore yields 2513 N push at 0.5 MPa, while the neighboring 63mm bore offers 1559 N and the 100mm bore provides 3927 N. Because the 200mm stroke is under 300mm, severe rod-bending side loads are less critical, but always guide the load. A plain cylinder does not hold load on air loss; the cushion only decelerates. For secure holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
Yes, the SI80BX200SH is discontinued. The direct replacement is the SAI80BX200SH. It is dimensionally interchangeable per ISO 15552, offering the same bore, stroke, output force, G3/8 port, and mounting interface. You simply install the SAI model into your existing fixtures.
This 80mm bore cylinder uses a G3/8 air port. The thrust ratings are: 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 force of 513 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80BX200SH replacement — usually within 7-8 hours.
