Airtac PB Pen-type Cylinder PB10X50SRLB
The AirTAC Airtac PB Pen-type Cylinder PB10X50SRLB 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 PB10X50SRLB
The AirTAC PB10X50SRLB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and piston rod, offering reliable durability in damp or mildly corrosive environments while saving valuable space on light end-of-arm tooling. Delivering 39.3 N of push force at 0.5 MPa, it occupies a practical middle ground for small-part handling.
This specific configuration includes an R axial air inlet for clean in-line plumbing and an LB mounting bracket for secure body attachment. The 4 mm rod utilizes an M8x1.0 rod-end thread, and the M5x0.8 port matches the 10 mm bore standard. A built-in piston magnet (-S) allows position detection using AirTAC reed or electronic switches. End-of-stroke deceleration is handled by a fixed TPU bumper, which is not field-adjustable.

| 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 PB10X50SRLB Is Used
PCB Pick-and-Place
Drives a small vacuum gripper on a pick-and-place head to lift electronic components, utilizing the lightweight pen-size body to minimize robot arm inertia.
Blister Pack Sorting
Pushes lightweight pharmaceutical blister packs into indexing chutes, where the fixed TPU bumper absorbs the impact of high-frequency 50 mm strokes.
Lab Dispenser Actuation
Actuates a micro-valve for chemical dispensing in analytical instruments, benefiting from the SUS304 construction to resist humid laboratory environments.
Is the Airtac PB Pen-type Cylinder PB10X50SRLB the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 24 N (about 60% of the 39.3 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift terms, this equates to lifting about 2 kg safely with a 2:1 margin. If you need less force, stepping down to the 6 mm bore yields 14.2 N push; if your jig requires more thrust, stepping up to the 12 mm bore provides 56.5 N push at the same 0.5 MPa.
Keep in mind that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the bumper only decelerates near stroke end rather than locking the load. For fail-safe holding, an external stop or rod lock is required. To order, confirm the 10 mm bore, 50 mm stroke, M5x0.8 port, S magnet, R axial inlet, and LB mount. Because the 4 mm rod is slender, always ensure coaxial thrust and add an external guide if side loads are present.
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 PB10X50SRLB FAQ
This 10 mm bore double-acting cylinder provides 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, a plain PB cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the end of the stroke and does not act as a lock. For vertical loads, you must add an external rod lock or mechanical stop.
