About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X650S
The SCT50X50X650S tandem cylinder delivers four fixed rod positions—0 mm, 50 mm, 650 mm, and a total extended travel of 700 mm—by pressurising its two piston sections independently or together. Each 50 mm bore section generates a push force of 982 N at 0.5 MPa (1767 N at 0.9 MPa), driven through a 20 mm diameter rod, making it suitable for sorting or multi-stop feeding tasks that require a long primary reach with a short secondary positioning step.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for contactless position feedback. The second stroke is a non-standard 650 mm, extending beyond the standard 500 mm limit, which makes this a made-to-order configuration. The body length A(SCT) is 243 mm, and the adjustable pneumatic cushion at each end is 21 mm, helping to manage inertia during high-speed travel up to 800 mm/s.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X650S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 50 / 650 mm |
| Total travel | 700 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). This configuration exceeds the 500 mm standard section stroke, so it is a non-standard / made-to-order build. 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) | 650 mm |
| P3 (both extended) | 700 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 SCT50X50X650S Is Used
Two-Stage Part Diverting
Uses the 50 mm stroke to lift a diverter gate slightly and the 650 mm stroke to swing it fully across a conveyor, routing parts to one of two lanes with sensor-confirmed positions.
Long-Reach Multi-Depth Assembly
Advances a tool 650 mm to a workpiece, then uses the final 50 mm step to perform a controlled press-fit or insertion, with the magnet confirming the tool is clear before the next cycle.
Dual-Stop Pallet Transfer
Pushes a pallet 650 mm along a roller bed to a main station, then indexes it an additional 50 mm to a precise secondary location, using reed sensors to verify each stop.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X50X650S the Right Cylinder?
Choose the SCT50X50X650S when a single actuator must provide a short 50 mm positioning step and a long 650 mm transfer stroke, eliminating the complexity of two separate cylinders and their valving. If the 982 N push force at 0.5 MPa is insufficient, stepping up to the 63 mm bore (SCT63) provides 1559 N of push force per section. For a drop-in replacement, match the 50 mm bore, both the 50 mm and 650 mm strokes, PT port thread, and the integrated magnet (-S). With the 650 mm stroke section, ensure the load is guided or supported externally to prevent rod buckling and side-load damage during full extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 650 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 SCT50X50X650S FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (50 mm), second section extended (650 mm), and both sections extended for the total travel (700 mm). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it can replace two individual cylinders with 50 mm and 650 mm strokes that were previously used in sequence, provided the per-section force (982 N push at 0.5 MPa) is adequate for each step. The replacement must be an AirTAC SCT with the same 50 mm bore, 50 mm and 650 mm strokes, PT ports, and the -S magnet option to maintain sensor compatibility.
