About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S
The SCT50X50X500S is a double-acting tandem cylinder that delivers four fixed rod positions from its two piston sections: fully retracted (0 mm), first section extended (50 mm), second section extended (500 mm), and both sections extended for a total travel of 550 mm. Each 50 mm bore section generates a push force of 982 N at 0.5 MPa, driven through a 20 mm diameter rod with M16x1.5 threads.
A built-in magnet is embedded in the piston, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position feedback. The cylinder body has an A-length of 243 mm and uses adjustable air cushioning with a 21 mm cushion sleeve to manage end-of-stroke impact. This genuine AirTAC unit is suited for sorting or diverting tasks requiring sensor-confirmed stops.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 50 / 500 mm |
| Total travel | 550 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 50 mm |
| P2 (section 2) | 500 mm |
| P3 (both extended) | 550 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S Is Used
Two-Stage Sorting Gate
Uses the 50 mm stroke for a primary divert and the 500 mm stroke for a secondary lane, with sensors confirming each position.
Multi-Depth Pressing
Provides two pressing depths in one cycle: a light touch at 50 mm and a full insertion at 550 mm, confirmed by magnetic sensors.
Long-Reach Stop Pin
Acts as a retractable stop with a 50 mm intermediate position for thin parts and 550 mm for larger components on a conveyor.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S the Right Cylinder?
Choose the SCT50X50X500S when your application needs four distinct mechanical stop positions with sensor feedback, avoiding the complexity of two separate cylinders and external stops. The 50 mm and 500 mm strokes provide a compact retracted length with a long working reach. If higher thrust is needed, consider stepping up to the 63 mm bore, which provides 1559 N of push force per section at 0.5 MPa. For replacement, match the 50 mm bore, both 50 mm and 500 mm section strokes, PT port thread, and the -S magnet option. Because the second stroke is 500 mm, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 500 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X500S FAQ
This cylinder provides four discrete stop positions: 0 mm (retracted), 50 mm (first section), 500 mm (second section), and 550 mm (both sections extended). The positions are fixed by the two stroke lengths.
Only if you need the specific multi-position functionality. It replaces an AirTAC SCT with a 50 mm bore, 50 mm and 500 mm strokes, PT ports, and an -S magnet. A standard SC cylinder cannot provide the same four discrete stops.
