Airtac SDAD Double Rod Slim Cylinder SDAD80X90B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X90B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 90mm 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 SDAD80X90B
The AirTAC SDAD80X90B is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding exactly 2267.8 N of force at 0.5 MPa in each direction. This symmetry is a major advantage when driving rigid loads that require balanced push and pull dynamics.
Equipped with male M22x1.5 threads on both 25 mm rod ends, this version simplifies direct mechanical attachment. The short body geometry saves axial mounting depth compared to traditional round-body units. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable air cushions. Note that this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to an -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X90B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X90B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 SDAD80X90B Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to keep a tracking roller steady, ensuring balanced tension on material webs during continuous feed operations.
Symmetric Lift Station
Drives a rigid vertical platen where equal 2267.8 N push and pull forces prevent binding, safely lifting loads around 115.6 kg with a 2:1 margin.
Dual-End Transfer Arm
Mounts a grip fixture on the male M22x1.5 rod end while the opposite side actuates a mechanical dog, triggering external limit valves in tight spaces.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X90B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD63 provides 1401.5 N at 0.5 MPa, while stepping up to the SDAD100 yields 3524.9 N. The 80 mm bore offers a computed safe working load of roughly 1361 N (about 60% of the 0.5 MPa rating), translating to a vertical lift capacity of approximately 115.6 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting and allows mounting a tool on one end and a dog on the opposite side. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the stroke end and does not act as a lock. For load holding, integrate an external rod lock or pilot-operated check valve. This configuration confirms an 80 mm bore, 90 mm stroke, 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 SDAD80X90B FAQ
The force is equal 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.
Yes, the through-rod protrudes from both sides, allowing you to drive a tool on one male M22x1.5 end while using the opposite end for a dog or secondary mechanism. The design also resists twisting, improving stability for dual-end setups.
