About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X700S
The SCT63X300X700S is a tandem multi-position pneumatic cylinder that delivers four distinct, repeatable rod positions: fully retracted (0 mm), 300 mm, 700 mm, and the full combined travel of 1000 mm. By pressurizing either or both of its two piston sections, you gain fixed mechanical stops without the complexity of servo controls. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa.
This model features a built-in magnet (-S suffix) along the 20 mm diameter rod, allowing direct mounting of CMSG, DMSG, or EMSG sensors for position feedback. The non-standard 700 mm stroke section requires a made-to-order configuration, making this a specialized solution for long-reach, multi-stop tasks. The cylinder body uses a tie-rod construction with a 28 mm adjustable air cushion and PT1/4 ports, providing reliable deceleration at each end of the 1000 mm total travel.

| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 300 / 700 mm |
| Total travel | 1000 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). 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) | 300 mm |
| P2 (section 2) | 700 mm |
| P3 (both extended) | 1000 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 SCT63X300X700S Is Used
4-Position Diverter Gate
Direct products to four separate conveyor lanes by stopping the cylinder rod at 0, 300, 700, and 1000 mm, using the built-in magnet for sensor confirmation at each position.
Multi-Depth Insertion Press
Install components at two distinct depths (300 mm and 700 mm) in a single cycle, with the 1559 N push force per section handling light-to-medium press-fit operations.
Long-Reach Multi-Stop Feeder
Advance parts in three precise increments across a 1-meter stroke for a progressive assembly or packaging station, eliminating the need for a servo-driven linear actuator.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X700S the Right Cylinder?
Select the SCT63X300X700S when your process needs four fixed stopping points along a 1-meter stroke, such as a multi-depth insertion or a diverter gate with a long travel. This tandem unit replaces the need for two separate 63 mm bore cylinders with external hard stops, simplifying mounting and plumbing. If your force requirement is lower, stepping down to a 50 mm bore (982 N push per section at 0.5 MPa) can reduce air consumption; for higher force, the 80 mm bore provides 2513 N per section.
For replacement, match an AirTAC SCT with a 63 mm bore, both a 300 mm and a 700 mm stroke section, PT thread, and the -S magnet option. Because the 700 mm section exceeds the 500 mm standard stroke limit, this is a non-standard item. For strokes this long, ensure the rod is externally guided or the load is centered to prevent side-loading and bending of the 20 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 300 + 700 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 SCT63X300X700S FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 300 mm (first section extended), 700 mm (second section extended), and 1000 mm (both sections extended for full travel). The 700 mm stroke section is non-standard and made-to-order.
The SCT tandem cylinder integrates two piston sections on a single rod line, giving you four fixed positions from one compact assembly. This eliminates the alignment and mounting complexity of two independent cylinders with external stops, and the single rod ensures a straight-line motion path. The built-in magnet allows you to monitor all four positions with standard AirTAC sensors.
