Airtac PB Pen-type Cylinder PB16X275SU
The AirTAC Airtac PB Pen-type Cylinder PB16X275SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 275mm 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 PB16X275SU
The AirTAC PB16X275SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling weight to an absolute minimum. Delivering 100.5 N of push force at 0.5 MPa, it provides robust thrust for its 16 mm bore.
This specific configuration includes a built-in piston magnet for position detection and a U-type back cover with a 90-degree perpendicular air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. Because the stroke extends to 275 mm, the slender Ø5 mm rod requires external guidance to prevent side-load damage, and the fixed TPU bumper at each end handles end-of-stroke deceleration.

| Rod diameter | Ø5 mm |
| Stroke | 275 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 |

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 PB16X275SU Is Used
PCB Depaneling Router
Actuates a tooling carriage to singulate printed circuit boards, utilizing the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame.
Package Divert Gate
Pushes lightweight cardboard cartons off a sorting line, where the stainless barrel withstands occasional washdowns and the 275 mm stroke clears the belt edge.
Lab Sample Dispenser
Drives a pipette head across testing stations, relying on the -S magnet to trigger reed or electronic switches for precise fluid volume metering.
Is the Airtac PB Pen-type Cylinder PB16X275SU the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø12 bore if your payload is lighter, which yields 56.5 N push at 0.5 MPa, or stepping up if you require more thrust—though Ø16 is the largest in this pen-size family, offering 100.5 N at 0.5 MPa. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa figure) to account for seal friction and smooth travel. For vertical applications, this equates to lifting about 5.1 kg with a sane 2:1 safety margin.
Confirm your ordering essentials: 16 mm bore, 275 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the U 90-degree side inlet. Note that a plain PB body does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of stroke. For fail-safe positioning, an external rod lock or mechanical stop is required.
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 PB16X275SU FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, with a maximum push of 140.7 N and pull of 126.9 N at the 0.7 MPa pressure limit. It operates between 0.15-0.7 MPa at speeds 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 an adjustable air cushion or a locking brake. If cycling heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber, and use an external stop if you need to hold position on air loss.
