Airtac PB Pen-type Cylinder PB10X50SR
The AirTAC Airtac PB Pen-type Cylinder PB10X50SR is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 50mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB10X50SR
The AirTAC PB10X50SR is a double-acting JIS pen-size mini cylinder engineered for high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This 10mm bore model generates 39.3 N of push force and 33 N of pull force at 0.5 MPa, operating through an M5x0.8 port.
Equipped with a built-in piston magnet (S code), it supports AirTAC reed or electronic switches for precise position detection. The R axial inlet allows for clean in-line plumbing. Travel is capped by a fixed TPU bumper at each end rather than an adjustable air cushion. Because the rod is a slender 4mm diameter, you should maintain coaxial thrust and avoid side loading to prevent guide wear over the 50mm stroke.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB10X50SR Is Used
PCB Pick-and-Place
Drives a small vacuum gripper on a pick-and-place head to lift delicate printed circuit boards, utilizing the 2 kg safe vertical lift capacity without stressing the lightweight robotic arm.
Carton Flap Folding
Extends a narrow silicone flap-finger on a packaging line to tuck minor carton flaps, relying on the fixed TPU bumper to absorb the impact of high-frequency cycling at 50mm stroke.
Lab Dispenser Actuation
Moves a micro-pipette or dispensing valve in a wet laboratory setting, where the SUS304 stainless barrel resists ambient moisture and chemical vapors during precise fluid routing.
Is the Airtac PB Pen-type Cylinder PB10X50SR the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 24 N, which accounts for seal friction by loading the cylinder to about 60% of its 39.3 N theoretical push at 0.5 MPa. In vertical lift terms, this equates to lifting about 2 kg with a sane 2:1 safety margin. If your payload is lighter, stepping down to the 6mm bore yields 14.2 N push at 0.5 MPa; if you need more thrust, stepping up to the 12mm bore provides 56.5 N. Remember that a plain PB body does not hold its position if air pressure drops or the valve is centered, so an external rod lock is required for fail-safe holding. To order, confirm the 10mm bore, 50mm stroke, M5x0.8 port, S magnet, and R axial back cover.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB10X50SR FAQ
This double-acting cylinder outputs 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it outputs 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
The fixed TPU bumper only decelerates the piston over the last few millimeters of stroke; for high-speed cycles with real tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold position on air loss, so an external stop is needed for fail-safe holding.
