AIRTACSI32X125ISO 15552 Pneumatic Cylinder, Double Acting – 32 mm Bore, 125 mm Stroke, 1/8 in Ports, Adjustable Cushioning

Product Description

What this part is: AirTAC SI32X125 pneumatic cylinder. Manufacturer: AirTAC. Part Number: SI32X125. Series: SI. Standard: ISO 15552, originally ISO 6431. Bore: 32 mm. Stroke: 125 mm. Cylinder Action: double acting. Operating Pressure: 0.1 to 1.0 MPa (15 to 145 psi, 1 to 10 bar). Proof Pressure: 1.5 MPa (215 psi, 15 bar). Port Size: 1/8 in. Cushion Type: variable, adjustable at both ends. Adjustable Cushion Stroke: 27 mm. Speed Range: 30 to 800 mm/s. Operating Temperature: -20 to +80 °C (-4 to +176 °F). Medium: air, filtered to 40 micron. Material: aluminium alloy. Mounting Style: basic. Theoretical Output Force at 6 bar: 482 N (108 lbf) extend. Decoding the designation: SI is AirTAC’s ISO 15552 standard cylinder series. The 32 is the bore in millimetres and the 125 is the stroke in millimetres. Bore: 32 mm. Stroke: 125 mm. What these specs mean in practice: ISO 15552 fixes the mounting interface, so a 32 mm bore SI cylinder drops onto the same brackets, foot mounts and rod eyes as any other maker’s ISO 15552 32 mm cylinder, and a machine builder keeps the fixture and changes the cylinder. Operating Pressure: 1 to 10 bar. Theoretical Output Force at 6 bar: 482 N on the 804 mm² piston area, which is the figure a clamp or feed stroke is sized against. Proof Pressure: 15 bar, giving a 50 percent margin over the 10 bar working ceiling. Cushion Type: variable at both ends with an Adjustable Cushion Stroke of 27 mm — the needle at each end cap is set to bleed the cushion chamber, so end-of-stroke deceleration is tuned to the actual load rather than fixed at build. Speed Range: 30 to 800 mm/s, so the same cylinder covers a slow controlled feed and a fast return. The piston seal is built from two Y-form one-way seals, a compensating arrangement that holds pressure in both directions, breaks away at low pressure and wears slowly. The barrel is a profiled aluminium extrusion with no tie rods, which keeps the outside envelope clean and resists corrosion. Port Size: 1/8 in. Operating Temperature: -20 to +80 °C. Medium: air filtered to 40 micron. Quantity and configuration: Unit Quantity: 1 Pc. One cylinder in the basic mounting build. Interchange guidance: Mounting brackets for the SI series are separate catalogue items in the codes FA, FB, CA, CB, CR, LB, TC, FTC, TCM1 and TCM2. Within the series the SID is the double-rod build and the SIJ the stroke-adjustable build on the same bore range. Because the mounting dimensions are set by ISO 15552, the cylinder interchanges dimensionally with 32 mm bore ISO 15552 cylinders from other makers. Searchable variants of the number: SI32X125, SI 32X125, SI 32 X 125, SI32-125, SI-32-125, SI32*125.
