Airtac PB Pen-type Cylinder PB16X27SU
The AirTAC Airtac PB Pen-type Cylinder PB16X27SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 27mm 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 PB16X27SU
The AirTAC PB16X27SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency tasks. It supplies a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, driven through an M5x0.8 port. The SUS304 stainless barrel and rod provide durable resistance in damp or mildly corrosive settings, keeping the unit slim enough for tight jig clearances.
This specific configuration includes a built-in piston magnet (-S) for position sensing and a U-type back cover featuring a 90-degree perpendicular air inlet for flat plumbing. Travel is managed by a fixed TPU bumper at each end; because it is not an adjustable air cushion, metering out the exhaust or adding an external shock absorber is advised when moving real tooling mass at higher speeds.

| 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 PB16X27SU Is Used
PCB Depaneling Ejector
Pushes singulated circuit boards out of a routing fixture with precise 27 mm travel, using the 100.5 N extend force to clear the cutting bit zone.
Carton Flap Tucker
Folds small corrugated flaps prior to tape sealing on a compact packaging line, benefiting from the flat 90-degree U inlet to keep the manifold close to the frame.
Lightweight Vertical Lift
Raises delicate electronic sensors into a test socket, safely lifting parts under 5.1 kg while the integrated magnet confirms the fully raised position.
Is the Airtac PB Pen-type Cylinder PB16X27SU the Right Cylinder?
Choosing this 16 mm bore yields the highest standard force in the PB family, delivering 100.5 N of push at 0.5 MPa. If your task is lighter, stepping down to the 12 mm bore provides 56.5 N of push, which may better suit delicate part handling. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa rating) to account for seal friction and smooth travel, equating to a vertical lift capacity of about 5.1 kg with a 2:1 safety margin.
When ordering, confirm the 27 mm stroke, the M10x1.0 rod-end thread, the U 90-degree side inlet, and the -S magnet for AirTAC reed or electronic switches. Note that a standard PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe load holding. The slim Ø5 mm rod is built for coaxial thrust, so avoid side loads and add a linear bearing if guiding off-axis components.
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 PB16X27SU 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 decelerate the piston over the last few millimeters, which is not field-adjustable. The -S code means it has a built-in magnet compatible with AirTAC reed or electronic switches for end-of-stroke detection.
