This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX10, 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 Airtac SI160 Standard Cylinder SI160BX10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 10mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX10, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160BX10 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 10 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160BX10, retaining the exact ISO 15552 mounting interface, output force, and accessories. This specific SKU lacks a magnet (-S), so it cannot accept position switches.
The SAI upgrade features a revised piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. It also introduces lock variants (SAIL, BSAI) absent in the SI line. The SUS304 stainless rod (B) offers corrosion resistance, and a Viton H seal option raises the thermal limit to 150 C.

The SAI160BX10 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).
Applies 10053 N of thrust at 0.5 MPa for seating large bearings or compressing dense assemblies in automated machinery.
Secures heavy steel weldments or cast components during machining operations using the 9425 N pull force.
Executes 10 mm high-impact stamping or swaging tasks where massive immediate force is required.
To replace the discontinued SI160BX10, order the SAI160BX10. Verify the ISO 15552 mounting interface, 160 mm bore, 10 mm stroke, G3/4 port, and M36x2 rod thread match your fixture. Because this SKU lacks a magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, order an SAI equivalent with the S suffix. Sizing down, a 125 mm bore provides 6136 N push at 0.5 MPa; sizing up to 200 mm yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. Even at 10 mm stroke, ensure rigid guidance to prevent rod bending under offset loads.
Replacement checklist
Yes, the SI160BX10 is discontinued. The direct replacement is the SAI160BX10. It matches the ISO 15552 mounting interface, 160 mm bore, 10 mm stroke, force, and G3/4 port, fitting existing fixtures perfectly.
The 160 mm bore uses a G3/4 port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160BX10 replacement — usually within 7-8 hours.
