Airtac SDAD Double Rod Slim Cylinder SDAD80X50B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X50B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 50mm 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 SDAD80X50B
The AirTAC SDAD80X50B is a double-acting, double-rod compact cylinder featuring a 50 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical on extension and retraction. This geometry yields exactly 2267.8 N of force at 0.5 MPa in both directions, preventing asymmetric load behavior.
This specific SKU includes male M22x1.5 thread on the 25 mm rods and lacks a piston magnet. The short body design minimizes axial footprint compared to standard round-body options. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston rather than locking it.
Airtac SDAD Double Rod Slim Cylinder SDAD80X50B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X50B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M14×1.5 female / M22×1.5 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SDAD80X50B Is Used
Symmetric Lift Station
Drives a 100 kg lifting platform with equal push and pull force, ensuring stable vertical travel without sagging on the return stroke.
Anti-Twist Guide Rail
Uses the dual-end through-rod to maintain strict linear alignment for a heavy sliding carriage, resisting torsional deflection.
Dual-End Transfer Arm
Mounts a gripping jaw on one rod end and a mechanical dog on the opposite end to trip external limit switches during cycling.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X50B the Right Cylinder?
When sizing this 80 mm bore, stepping down to the SDAD63 provides 1401.5 N at 0.5 MPa, while moving up to the SDAD100 yields 3524.9 N. Based on the 2267.8 N output, a safe working load is roughly 1361 N, allowing a vertical lift of about 115.6 kg with a 2:1 margin.
The through-rod design provides excellent anti-rotation resistance and permits mounting a tool on one end with a dog on the opposite side. Note that air loss will cause drift, as the NBR bumper only decelerates and does not hold position; use an external rod lock for load holding. This configuration specifies a PT3/8 port, male M22x1.5 rod threads, and no 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 SDAD80X50B FAQ
The force is identical in both directions due to the double-rod design. It generates 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet. You must select the -S variant to use AirTAC reed or electronic switches. The male M22x1.5 threaded rods on both ends still allow dual-end tool mounting.
