Airtac SCD Standard Cylinder SCD63X170
The AirTAC Airtac SCD Standard Cylinder SCD63X170 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 170mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD63X170
The SCD63X170 is a double-acting pneumatic cylinder with a through-rod design, guaranteeing identical force and speed in both directions. At 0.5 MPa, it provides a balanced 1402 N of thrust for both extension and retraction, making it ideal for applications where symmetry is critical.
This 63 mm bore model features a 20 mm diameter rod protruding from both end caps and uses PT1/4 ports. The adjustable air cushion at each end is 28 mm long, and the retracted body length A(SCD) is 210 mm. It operates reliably on filtered air from 0.15 to 1.0 MPa.
Airtac SCD Standard Cylinder SCD63X170 Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD63X170 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 170 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| 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 | Up to 1500 mm |
Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCD Standard Cylinder SCD63X170 Is Used
Two-Sided Tooling
The rod extending from both ends allows you to mount a tool on the front and a stopper or confirmation flag on the rear, simplifying setups in transfer machines.
Symmetric Clamping
Delivers exactly 2523 N of clamping force at 0.9 MPa in both directions, ensuring uniform pressure regardless of actuation direction for assembly fixtures.
Shuttle Tables
The equal push-pull force and speed make this 170 mm stroke cylinder perfect for reciprocating shuttle mechanisms where cycle consistency is paramount.
Is the Airtac SCD Standard Cylinder SCD63X170 the Right Cylinder?
Choose the SCD63X170 when your application needs a balanced push-pull force of 1402 N at 0.5 MPa. If you require more force, stepping up to the SCD80 bore provides 2268 N at the same pressure. For less force, the SCD50 bore delivers 825 N. If your task only needs a single working direction, a standard SC single-rod cylinder is a simpler, more cost-effective choice.
For a direct replacement, match the 63 mm bore, 170 mm stroke, PT thread, and basic mounting. Adding the -S magnet option enables position sensing with CMSG/DMSG sensors. For strokes over 300 mm on this bore, consider an external guide rail to prevent rod buckling under side loads, as the through-rod provides guidance but is not a rigid linear bearing.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ 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 Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD63X170 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 1402 N, at 0.7 MPa it provides 1962 N, and at the maximum operating pressure of 0.9 MPa it reaches 2523 N.
Choose the SCD when you need perfectly equal force and speed in both directions, a rear rod end for mounting sensors or cams, or improved resistance to rod rotation. The dual-rod bearing support also offers better side-load tolerance than a standard single-rod cylinder.
