About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X10S
The AirTAC SCT63X160X10S is a double-acting multi-position tandem cylinder that provides four fixed rod positions: fully retracted (0 mm), 10 mm, 160 mm, and the combined total travel of 170 mm. Each piston section delivers a push force of 1559 N at 0.5 MPa, rising to 2805 N at 0.9 MPa, making it a powerful solution for applications requiring two distinct extended stops from a single compact unit. The 20 mm diameter rod and 28 mm air cushion at each end ensure smooth deceleration.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable, non-contact position feedback at each stop. The standard TPU seals and PT ports suit general industrial environments, while the tie-rod construction offers robust serviceability. With a body length of 249 mm, it integrates easily into machinery needing a short 10 mm advance and a longer 160 mm stroke without the complexity of two separate cylinders.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 160 / 10 mm |
| Total travel | 170 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) | 160 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 170 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 SCT63X160X10S Is Used
Two-Stage Sorting Gate
Use the 10 mm stroke to nudge a part into an inspection zone and the 160 mm stroke to fully divert rejected items onto a separate conveyor lane, all with sensor-confirmed positions.
Dual-Depth Press Feed
Advance a stamping die to a 10 mm pre-press position for alignment, then drive the full 160 mm stroke for the forming operation, ensuring consistent material engagement.
Adhesive Dispenser Positioning
Move a dispensing head to a 10 mm standby height above a workpiece and a 160 mm retracted clearance position for part changeover, with the magnet confirming each safe state.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X10S the Right Cylinder?
Select the SCT63X160X10S when your process needs a short, precise 10 mm positioning step and a longer 160 mm travel from the same actuator, eliminating the need for two single-stroke cylinders and their associated mounting hardware. If your force requirement is lower, consider stepping down to the 50 mm bore SCT, which provides 982 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both strokes (160 mm and 10 mm), PT port thread, basic mounting, and the -S magnet option. Given the 160 mm stroke on the primary section, ensure the guided load is aligned to prevent excessive side-loading and rod bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 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 SCT63X160X10S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 10 mm (first section extended), 160 mm (second section extended), and 170 mm (both sections extended, total travel).
The SCT integrates two strokes on a single common rod line, guaranteeing fixed, repeatable positions at 10, 160, and 170 mm without the alignment complexity, extra mounting brackets, and sequential valve logic required by two independent actuators. It is a drop-in tandem unit that saves space and simplifies pneumatic circuit design.
