About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X190X10
The SCT50X190X10 tandem cylinder delivers four fixed rod positions—0 mm, 10 mm, 190 mm, and the combined 200 mm total travel—by pressurising one or both of its 50 mm bore sections. Each piston section generates approximately 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), making it suitable for tasks that need a long primary stroke with a short secondary positioning step.
Built on a robust tie-rod design with a 20 mm diameter piston rod and PT1/4 ports, this cylinder uses adjustable pneumatic cushioning over a 21 mm length to manage end-of-stroke deceleration. The body length A(SCT) is 243 mm, providing a compact tandem package for its 200 mm total stroke capability.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X190X10 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X190X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 190 / 10 mm |
| Total travel | 200 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) | 190 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 200 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 SCT50X190X10 Is Used
Two-Stage Sorting Gate
Uses the 190 mm stroke to divert a package from a main conveyor and the 10 mm stroke to nudge it onto a secondary lane, providing a compact, all-pneumatic sorting solution.
Long-Feed with Short Clamp
Advances a workpiece 190 mm into a fixture, then applies a short 10 mm clamping stroke to hold it securely for machining or assembly.
Two-Depth Insertion
Inserts a component 190 mm into an assembly, then uses the final 10 mm position to press it to a controlled depth, ensuring consistent seating without damaging the part.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X190X10 the Right Cylinder?
This 4-position configuration is ideal when a process requires a long 190 mm travel for part transfer and a precise 10 mm offset for a secondary operation like a short press or ejection, eliminating the need for two separate actuators. If higher force is needed, stepping up to the 63 mm bore SCT provides 1559 N of push per section at 0.5 MPa. For a direct replacement, match the 50 mm bore, both 190 mm and 10 mm strokes, PT port thread, and basic mounting style exactly. With a section stroke of 190 mm, rod deflection is minimal, but if the load is not guided, consider external linear rails to protect the rod bearing from side forces.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 190 + 10 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 SCT50X190X10 FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (10 mm), second section extended (190 mm), and both sections extended for the full 200 mm total travel. The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it can replace a 10 mm stroke and a 190 mm stroke cylinder in a space-constrained application, but the replacement must be an AirTAC SCT50X190X10 with matching PT ports and basic mounting. The force output is 982 N per actuated section, not a combined force, so verify that the single-section thrust meets your load requirements for each position.
