About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X190X60
The SCT63X190X60 is a tandem multi-position cylinder that delivers four distinct, repeatable rod positions without external stops. By pressurising either or both of its two piston sections, the rod extends to exactly 0 mm, 60 mm, 190 mm, or the full combined travel of 250 mm.
Each 63 mm bore section generates a push force of 1559 N at 0.5 MPa, rising to 2805 N at 0.9 MPa, driven through a rigid 20 mm diameter piston rod. The tie-rod construction incorporates a 28 mm adjustable air cushion on each end, and the main body has an A-length of 249 mm, making it a compact solution for multi-stop linear tasks.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X190X60 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X190X60 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 190 / 60 mm |
| Total travel | 250 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) | 190 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 250 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 SCT63X190X60 Is Used
Two-Stage Sorting Gate
A 190 mm stroke diverts a product from a main conveyor, and a precise 60 mm secondary stroke pushes it into one of two separate chutes, all controlled by simple 5/3 valves.
Multi-Depth Clamping
Clamp a family of parts with two different thicknesses. The first 60 mm stroke applies a light hold, and the full 190 mm stroke provides a deep, secure clamp for larger workpieces.
Sequential Part Feeding
Use the 60 mm stop to isolate a single component from a stack, then the 190 mm stroke to transfer it fully into a nest, ensuring reliable singulation and placement.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X190X60 the Right Cylinder?
Choose the SCT63X190X60 when an application needs a simple, pneumatic-only method to achieve four fixed stopping points, avoiding the complexity of servo motors or multiple cylinders with external hard stops. The 190 mm and 60 mm stroke combination is ideal for a long primary advance with a short secondary positioning move. If higher force is needed, consider stepping up to the 80 mm bore SCT, which provides 2513 N of push per section. This model is a direct replacement only for another AirTAC SCT63X190X60 with matching PT ports and basic mounting.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 190 + 60 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 SCT63X190X60 FAQ
This cylinder provides four discrete rod positions: fully retracted (0 mm), the first section extended (60 mm), the second section extended (190 mm), and both sections extended for the total travel of 250 mm.
Yes, it can replace two SC63 cylinders with 190 mm and 60 mm strokes that are mounted back-to-back, providing the same four-position functionality in a single, pre-aligned package with a common rod. It is not a drop-in replacement for ISO 15552 cylinders.
