Airtac SDAD Double Rod Slim Cylinder SDAD40X100B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X100B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 100mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.

About the Airtac SDAD Double Rod Slim Cylinder SDAD40X100B
The AirTAC SDAD40X100B is a double-acting, double-rod compact cylinder featuring a 40 mm bore and 100 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical on extend and retract strokes. This geometry yields perfectly symmetric thrust, generating 527.8 N of force in each direction at 0.5 MPa. The through-rod design inherently resists mechanical twisting, providing stable guidance for rigid payloads.
This specific SKU includes male M14x1.5 thread on both 16 mm rod ends, allowing direct mounting of tooling without extra adapters. The short body profile saves valuable axial depth in tight machinery. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs impact shock rather than acting as an adjustable air cushion. Note that this configuration lacks a piston magnet, so position sensing is not supported on this unit.
Airtac SDAD Double Rod Slim Cylinder SDAD40X100B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X100B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 100 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 male (B) |
| 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 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
| Max standard stroke | Up to 120 mm |
Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Where the Airtac SDAD Double Rod Slim Cylinder SDAD40X100B Is Used
Precision Edge Guiding
Uses the equal 527.8 N force to tension and guide web materials without deflecting or twisting the web path.
Dual-End Transfer Arm
Mounts a grip on one male M14x1.5 end and a dog on the opposite to actuate external limits during part transfer.
Symmetric Lift Station
Raises and lowers a 26.9 kg platen vertically, relying on the through-rod to prevent platform rotation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X100B the Right Cylinder?
When sizing this unit, compare its 527.8 N thrust at 0.5 MPa against adjacent bores. Dropping down to the SDAD32 provides 345.6 N, whereas stepping up to the SDAD50 yields 824.7 N. Choose the 40 mm bore when your application demands moderate symmetric force within a compact footprint.
The through-rod architecture prevents rotation and permits driving a tool on one end while using the opposite end for secondary operations. Because this is a double-acting pneumatic actuator, it will not hold a load if air pressure drops or the valve centers; the piston will drift. For load-holding requirements, integrate an external rod lock or pilot-operated check valve. This model features male M14x1.5 rod threads, a PT1/8 port, and no piston magnet.
Quick checklist
- ✓ Need equal force both directions?
- ✓ Anti-rotation / dual-end mounting?
- ✓ Space for a rod that exits both ends
- ✓ Port/thread type (PT)
- ✓ 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 Leave clearance for the rod exiting both ends.
- check Avoid side load on either rod end.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAD Double Rod Slim Cylinder SDAD40X100B FAQ
The force is identical in both directions due to the double-rod design. It generates 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one male M14x1.5 end while using the other for secondary tasks. The dual-rod geometry also provides excellent anti-rotation resistance for the payload.
