Airtac PB Pen-type Cylinder PB16X55SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X55SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 55mm 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 PB16X55SCB
The AirTAC PB16X55SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It provides a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing an M5x0.8 air port and an M10x1.0 rod-end thread. The SUS304 stainless barrel and slim round body drastically reduce payload on end-of-arm tooling while resisting moisture in washdown-adjacent environments.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a CB double clevis back cover for pivoting loads. It relies on a fixed TPU bumper at each end to decelerate the stroke, meaning operators should meter-out exhaust or add external shocks when cycling high masses at speed. Plan for a safe working load of roughly 60 N at 0.5 MPa to account for seal friction and smooth travel.

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 PB16X55SCB Is Used
Pivoting Component Diverter
Ideal for swinging a lightweight gate on a packaging line, utilizing the CB double clevis to articulate the arm while providing 100.5 N of extend force at 0.5 MPa.
Small Vertical Lift Station
Moves lightweight plastic cassettes upward within an inspection machine, safely lifting parts weighing up to 5.1 kg with a 2:1 safety margin at 0.5 MPa.
Sensor-Verified Sorting
Pushes small electronic components into a reject chute, using the built-in magnet with a solid-state switch to confirm stroke completion before the conveyor advances.
Is the Airtac PB Pen-type Cylinder PB16X55SCB the Right Cylinder?
Choosing this 16 mm bore actuator involves balancing your force requirements with mounting geometry. If you need less thrust, the 12 mm bore version offers 56.5 N push at 0.5 MPa; stepping up is not possible as this is the largest standard diameter in the family. The CB double clevis on this unit is ideal for articulating mechanisms, and the -S magnet enables position feedback. Confirm your porting matches the M5x0.8 inlet and that your 55 mm stroke fits the assembly.
Because this is a double-acting cylinder, it does not inherently hold its position if air pressure drops or the valve is centered—the piston will drift. An external rod lock or mechanical stop is mandatory for fail-safe vertical holding. Furthermore, the Ø5 mm piston rod is designed for pure coaxial thrust; if your application involves side-loading or longer extensions, integrate an external linear bearing to prevent binding.
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 PB16X55SCB 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 to absorb impact over the final few millimeters; this is not an adjustable air cushion, so add an external shock absorber for heavy high-speed loads. The CB back cover is a double clevis designed specifically for pivoting rod-end loads.
