Airtac STA Single Acting Compact Guided Cylinder STA50X10B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA50X10B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø50mm bore and 10mm stroke. Air pulles the rod and an internal spring returns it, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac STA Single Acting Compact Guided Cylinder STA50X10B
The AirTAC STA50X10B is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It provides a robust 717.7 N of net pull force at 0.5 MPa, meaning the quoted power already accounts for the spring resistance. This makes it highly effective for tensioning or pulling heavy loads within a tight axial footprint.
Featuring a 50 mm bore and a 10 mm stroke, this riveted-body unit saves mounting depth where standard round-body cylinders cannot fit. It uses a male M18x1.5 piston rod thread and a PT1/4 air port. A fixed NBR bumper decelerates the stroke end, as there is no adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without changing to an -S variant.
Airtac STA Single Acting Compact Guided Cylinder STA50X10B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA50X10B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | Fixed NBR bumper |
| Max standard stroke | Up to 30 mm |
Specifications follow the official AirTAC SDA-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Net Output Force (Ø50mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 718 N |
| 0.7 MPa | 1048 N |
These are NET output forces — the return-spring force is already deducted. Single-acting pull only; the spring performs the opposite stroke. Size with a safety margin.

Where the Airtac STA Single Acting Compact Guided Cylinder STA50X10B Is Used
Heavy-Duty Cable Tensioning
Uses the 717.7 N net pull to draw tension cables taut, with the spring reliably extending the rod to release slack when the air supply is cut.
Pneumatic Lift Gate Return
Pulls a weighted gate closed using the male M18x1.5 rod end, safely handling a vertical lift load of about 36.6 kg with a 2:1 margin.
Pallet Hold-Down Clamps
Draws securing clamps inward against heavy pallet loads in compact packaging cells, relying on the short riveted body to fit tight machine frames.
Is the Airtac STA Single Acting Compact Guided Cylinder STA50X10B the Right Cylinder?
When sizing this model, compare its 717.7 N net pull at 0.5 MPa against adjacent bores. Stepping down, the STA40 yields 445.1 N, while stepping up to the STA63 provides 1225.5 N. A safe working load is approximately 431 N, which allows a vertical lift of roughly 36.6 kg with a 2:1 safety margin.
Remember the 30 mm maximum standard stroke ceiling and the spring-extend behavior: if air pressure drops, the spring drives the rod out, so it will not hold a mid-stroke load without an external device. This configuration confirms a 50 mm bore, 10 mm stroke, PT1/4 port, no magnet, and a male M18x1.5 rod thread. Operating pressure must be 0.2-1.0 MPa to overcome the spring.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Stroke ≤ 30 mm (single-acting limit)
- ✓ Single air line saves a valve/port
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Remember the spring performs the return stroke.
- check Avoid side load on the short piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac STA Single Acting Compact Guided Cylinder STA50X10B FAQ
This cylinder delivers a net pull force of 717.7 N at 0.5 MPa and 1047.5 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, as at least 0.2 MPa is needed to overcome the internal return spring.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the STA50X10BS variant to enable sensing capabilities.
