Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 30mm and 10mm give 4 controllable stop positions across a 40mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S
The SCT40X30X10S creates four discrete rod positions—0, 30, 10, and 40 mm—by sequencing pressure to its two tandem piston sections. Each 40 mm bore section delivers about 628 N of push force at 0.5 MPa, making it a compact solution for short-throw sorting or diverting tasks where a standard cylinder would need external hard stops.
A built-in magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel for non-contact position feedback at every stop. The 16 mm diameter rod and 21 mm air cushion at each end help manage end-of-stroke impact, even in rapid cycling up to 800 mm/s.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 30 / 10 mm |
| Total travel | 40 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 30 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 40 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X30X10S Is Used
Two-Way Part Diverting
Uses the 30 mm and 40 mm extended positions to guide parts down two separate chutes from a single infeed conveyor, with the 10 mm stop acting as a staging point.
Multi-Level Label Apply
Positions a tamp pad at 10 mm for low-profile items and 40 mm for taller boxes, eliminating manual height adjustment between product changeovers.
Staged Clamping
Provides a light 10 mm pre-clamp position before applying full 40 mm travel clamping force, protecting delicate assemblies from sudden impact.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X10S the Right Cylinder?
Choose the SCT when you need fixed intermediate stops without the complexity of two separate cylinders and a bracket. The 30 mm and 10 mm strokes give four distinct tooling positions from a single compact assembly. If your load requires more force, stepping up to the 50 mm bore provides 982 N of push per section at the same pressure. For replacement, match the 40 mm bore, both 30 mm and 10 mm strokes, PT port thread, and the -S magnet option exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 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 SCT40X30X10S FAQ
The rod stops at four discrete positions: fully retracted (0 mm), first section extended (30 mm), second section extended (10 mm), and both sections extended for the total travel of 40 mm.
While external stops on an SC cylinder can create intermediate positions, the SCT provides built-in, repeatable stops with full bore force at each position. It is a more compact and reliable solution, but if replacing an existing SCT, you must match the 40 mm bore, both 30 mm and 10 mm strokes, and the integrated magnet option.
