Airtac PB Pen-type Cylinder PB10X50RLB
The AirTAC Airtac PB Pen-type Cylinder PB10X50RLB 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 PB10X50RLB
The AirTAC PB10X50RLB is a JIS pen-size double-acting single-rod mini cylinder engineered for tight jigs and light end-of-arm tooling. It features a slim SUS304 stainless steel barrel and piston rod, providing excellent durability in damp or mildly corrosive environments without adding unnecessary bulk. Delivering 39.3 N of push force at 0.5 MPa, it uses an M5x0.8 air port and an M8x1.0 rod-end thread for straightforward load coupling.
This 50 mm stroke unit is equipped with an R axial air inlet for in-line plumbing and an LB mounting bracket for secure body attachment. It relies on a fixed TPU bumper at each end to decelerate motion over the final few millimeters. Because the Ø4 mm piston rod is designed strictly for coaxial thrust, adding an external guide is recommended if dealing with off-axis loads over extended strokes.

| Rod diameter | Ø4 mm |
| Stroke | 50 mm |
| 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |

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 PB10X50RLB Is Used
PCB Pick-and-Place
Drives small vacuum heads in electronics assembly, utilizing the 39.3 N thrust to lift delicate boards while the slim body saves valuable manifold space.
Blister Pack Sorting
Pushes lightweight plastic trays into chutes at high frequency, where the fixed TPU bumpers absorb end-of-stroke impacts without requiring adjustment.
Lab Dispense Valve
Actuates micro-dispense nozzles for reagent application, benefiting from the SUS304 construction to resist humidity and chemical vapors.
Is the Airtac PB Pen-type Cylinder PB10X50RLB the Right Cylinder?
When sizing this actuator, stepping down to the Ø6 bore yields 14.2 N of push at 0.5 MPa, while stepping up to the Ø12 bore provides 56.5 N, allowing you to scale thrust precisely. For the PB10X50RLB, plan for a safe working load of roughly 24 N at 0.5 MPa, which equates to lifting about 2 kg vertically with a 2:1 safety margin. Confirm your ordering essentials: 10 mm bore, 50 mm stroke, M5x0.8 port, R axial inlet, and LB mount.
Note that a plain double-acting cylinder like this does not hold its position if air pressure is lost or the valve is centered; the piston will drift. If your application requires a fail-safe hold under load, you must incorporate an external stop or a dedicated rod lock.
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 PB10X50RLB FAQ
This double-acting cylinder delivers 39.3 N push and 33 N pull at 0.5 MPa, with maximum figures of 55 N push and 46.2 N pull at 0.7 MPa. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a maximum standard stroke of 200 mm.
This specific configuration does not include a sensor magnet. For cushioning, it uses fixed TPU bumpers at both ends rather than adjustable air cushions; at high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber.
