Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 50mm stroke. A single air port drives the pull stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.

About the Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB
The AirTAC PTB10X50SCB is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, and an internal spring pushes it back out. Because the powered stroke pulls against the rod-side area, this 10mm bore generates 23.5N of net pull at 0.5MPa (36.7N at 0.7MPa max). The built-in magnet enables position sensing, while the CB double clevis allows pivoting articulation.
If air pressure drops, the spring forces the rod into the extended position, providing a fail-safe out state for hold-down or return-to-home tooling. The SUS304 stainless barrel and slim body save space on end-of-arm robotics. Plan for roughly 14N of actual work (about 60% of the rated force) to account for seal friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 50 mm |
| Acting type | Single acting, pull type (spring extend) |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Return | Return spring (pull by air) |
| Max standard stroke | Up to 60 mm |
The spring holds the rod extended; applying air retracts it, and removing air lets the spring push the rod back out. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
Net Pull Force (Ø10mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 23.5 N |
| 0.7 MPa (max) | 36.7 N |
These are the usable pull forces after the return spring is subtracted, taken directly from the AirTAC single-acting thrust table. Minimum operating pressure is set by the spring, so this model needs at least the lower pressure shown to move.

Where the Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing into position, pulling the 4mm rod back to clamp thin materials before releasing air to spring-extend safely.
Wire Belt Tensioner
Applies steady retraction on a conveyor belt routing system, holding about 1.2kg of tension with a 2:1 safety margin at 0.5MPa.
Retract-to-Open Gate
Vents air to let the spring push the gate open during power loss, ensuring emergency access while keeping the pathway clear during normal operation.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB the Right Cylinder?
This 10mm bore provides 23.5N net pull at 0.5MPa. Sizing down, a 6mm bore yields only 7.1N, which is likely too weak for pivoting loads; sizing up to a 16mm bore jumps to 65N. The internal return spring requires at least 0.2MPa before motion begins. The CB double clevis is ideal for pivoting mechanisms, but ensure the load rotates freely to avoid side-loading the slender Ø4mm rod.
With a 50mm stroke, the thin 4mm rod needs external guidance if pushing off-axis. The fixed TPU bumper only softens the final few millimeters; at high cycling speeds with attached tooling mass, meter-out the exhaust or add an external shock absorber. This configuration includes the S magnet for electronic or reed switches.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe extend on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 0.7 MPa operating pressure.
- check Allow for spring force in the stroke direction.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X50SCB FAQ
This cylinder provides 23.5N of net pull at 0.5MPa and 36.7N at 0.7MPa maximum. Because an internal spring holds the rod extended, a minimum of 0.2MPa is required to overcome the spring and retract the rod.
The S suffix denotes a built-in piston magnet compatible with AirTAC reed or solid-state electronic switches. Cushioning relies on a fixed TPU bumper that decelerates the stroke only over the last few millimeters, so external shock absorption may be needed for heavy tooling.
