Airtac STA Single Acting Compact Guided Cylinder STA50X10
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA50X10 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 STA50X10
The AirTAC STA50X10 is a compact single-acting pull-type cylinder where air pressure retracts the rod and an internal spring extends it out. It yields 717.7 N of net pull at 0.5 MPa, reaching 1047.5 N at 0.7 MPa. This makes it well suited for pulling heavy loads or returning gates to an open resting state.
The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit. It features a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot accept magnetic switches; the -S variant is required for reed or electronic sensing.
Airtac STA Single Acting Compact Guided Cylinder STA50X10 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA50X10 |
|---|---|
| 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.

Thread: PT standard. SSA pushes out / spring returns; STA pulls in / spring extends. Related: SDA (double acting), SDAD (double rod), SDAJ (adjustable stroke).
Where the Airtac STA Single Acting Compact Guided Cylinder STA50X10 Is Used
Gate Return Tensioning
Uses the 717.7 N net pull to draw a heavy diverter gate inward against product flow, relying on the internal spring to push it back open when air is vented.
Pallet Hold-Down Pull
Secures tall pallet loads by pulling a retaining bar tight during transit, with the spring-extend function ensuring the bar retracts out of the way upon release.
Film Roll Core Extraction
Extracts heavy mandrels from finished packaging film rolls, taking advantage of the short 10 mm stroke and high retraction force to break the initial friction grip.
Is the Airtac STA Single Acting Compact Guided Cylinder STA50X10 the Right Cylinder?
When sizing this bore, note the STA40 provides 445.1 N net pull at 0.5 MPa, while the larger STA63 offers 1225.5 N. The 50 mm bore strikes a balance, offering a safe working load of roughly 431 N (about 60 percent of its 717.7 N rating) and a vertical lift capacity of approximately 36.6 kg with a 2:1 margin.
This configuration features a 10 mm stroke, a PT1/4 port, and a female M10x1.5 rod-end thread on a 20 mm rod. Remember the 30 mm maximum stroke ceiling for the series. Because the spring drives the rod out on air loss, it does not hold a mid-stroke load; use a double-acting SDA with an external rod lock if you need position holding without live pressure.
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 STA50X10 FAQ
This cylinder provides 717.7 N of net pull at 0.5 MPa and 1047.5 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, with a minimum of 0.2 MPa necessary to overcome the internal return spring.
No, this specific SKU does not include a piston magnet and therefore cannot accept magnetic switches. You must select the STA50X10S variant to enable sensing with AirTAC reed or electronic switches.
