Airtac PB Pen-type Cylinder PB16X50SRLB
The AirTAC Airtac PB Pen-type Cylinder PB16X50SRLB is a double-acting pen-size (mini) air cylinder with a Ø16mm 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 PB16X50SRLB
The AirTAC PB16X50SRLB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a 16 mm bore and 50 mm stroke. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping end-of-arm tooling lightweight.
This configuration includes an R axial air inlet for in-line plumbing and an LB mounting bracket for secure attachment. Air connections use an M5x0.8 port, while the Ø5 mm rod features an M10x1.0 end thread for load coupling. A built-in magnet (-S) enables position detection using AirTAC reed or electronic switches.

| 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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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 PB16X50SRLB Is Used
PCB Depaneling Jig
Actuates a routing blade in a tight electronics assembly cell where the slim stainless body resists flux fumes and saves valuable tooling space.
Pouch Sealing Press
Closes a small heat bar with 100.5 N of extend force at 0.5 MPa, cycling rapidly while the LB bracket keeps the unit firmly anchored.
Parts Divert Gate
Pushes lightweight plastic caps on a packaging line, using the built-in S magnet to confirm gate extension via an electronic switch.
Is the Airtac PB Pen-type Cylinder PB16X50SRLB the Right Cylinder?
When sizing this actuator, the PB12X30 offers a lighter 56.5 N push at 0.5 MPa, while the PB16X50SRLB provides the maximum 100.5 N push in this pen-size family. For practical sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction. This equates to lifting about 5.1 kg vertically with a sane 2:1 margin.
Remember that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For fail-safe positioning, an external stop or rod lock is required. To order, confirm the 16 mm bore, 50 mm stroke, M5x0.8 port, S magnet, R axial inlet, and LB bracket.
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 PB16X50SRLB FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so for high mass or speed, add an external shock absorber. The cylinder does not hold position on air loss, requiring an external rod lock for fail-safe holding.
