Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X50SN
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X50SN is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 80mm and 50mm give 4 controllable stop positions across a 130mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X50SN
The SCT63X80X50SN is a tandem multi-position pneumatic cylinder that delivers four fixed rod positions—0 mm, 80 mm, 50 mm, and the combined 130 mm total travel—from a single compact assembly. Each piston section provides 1559 N of push force at 0.5 MPa (2182 N at 0.7 MPa), driven by a 20 mm diameter rod with M16x1.5 threads. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing.
This unit is configured with NBR seals for standard temperature resilience and PT ports (PT1/4). With a 28 mm adjustable air cushion on each section, it decelerates loads smoothly even at speeds up to 800 mm/s. The body length A is 249 mm, making it a drop-in solution where two separate cylinders or external hard stops would consume more space and require extra valving.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X50SN |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 80 / 50 mm |
| Total travel | 130 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, 28 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) | 80 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 130 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X80X50SN Is Used
Two-Stage Part Diverting
Uses the 80 mm and 130 mm positions to route parts to two separate conveyor lanes from a single infeed point, controlled by pressurizing section one or both sections.
Sequential Clamping
Applies a light pre-clamp at the 50 mm position before engaging full clamping force at the 130 mm total travel, protecting delicate assemblies from impact.
Multi-Depth Pressing
Executes a shallow 50 mm press stroke and a deeper 80 mm stroke in one cycle, eliminating the need for a second actuator and reducing fixture complexity.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X50SN the Right Cylinder?
Choose this SCT63 model when your application needs four distinct mechanical stops without the complexity of servo control. The 80 mm and 50 mm strokes create asymmetric positions ideal for two-step feeding or sorting where the extension and retraction distances differ. If you need higher force, step up to the SCT80 bore, which delivers 2513 N push per section at 0.5 MPa; for a lighter, more compact design, the SCT50 bore offers 982 N. A direct replacement must match the 63 mm bore, both 80 mm and 50 mm strokes, PT1/4 ports, NBR seals, and the built-in magnet.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 50 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 SCT63X80X50SN FAQ
This cylinder provides four discrete mechanical stops: fully retracted (0 mm), the first section extended (80 mm), the second section extended (50 mm), and both sections extended for the total travel of 130 mm. The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it is designed to replace two individually mounted cylinders where space is limited and synchronized motion is not required. It provides the same per-section force (1559 N push at 0.5 MPa) as a standard SC63, but you must ensure the replacement matches both the 80 mm and 50 mm strokes, the NBR seal material, and the built-in magnet for sensor compatibility.
