Airtac PB Pen-type Cylinder PB16X225R
The AirTAC Airtac PB Pen-type Cylinder PB16X225R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 225mm 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 PB16X225R
The AirTAC PB16X225R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It utilizes a slim SUS304 stainless steel round barrel and piston rod, offering robust resistance in damp or mildly corrosive work areas. Generating 100.5 N of push force at 0.5 MPa, it provides substantial thrust within a highly space-efficient envelope.
This 16mm bore variant features an M5x0.8 air port and an R axial inlet for streamlined in-line plumbing. It reaches speeds of 50-800 mm/s and relies on a fixed TPU bumper at each end to decelerate the piston. Because the bumper only absorbs energy over the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber.

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 PB16X225R Is Used
Package Flap Folding
Drives a lightweight arm to tuck carton flaps on a packaging line, utilizing the 225mm stroke to reach across the box width before retracting into a compact footprint.
PCB Test Fixture
Lowers an electronic probe array onto printed circuit boards, where the stainless build resists flux fumes and the slim body avoids obstructing adjacent test points.
Textile Yift Lift
Pushes a small yarn guide upward to shift weaving patterns, taking advantage of the 100.5 N extend force to overcome light mechanical spring resistance.
Is the Airtac PB Pen-type Cylinder PB16X225R the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction at 0.5 MPa. For vertical lifts, this equates to raising about 5.1 kg with a sensible 2:1 safety margin. If you need slightly less thrust, the 12mm bore provides 56.5 N push at 0.5 MPa; stepping up is not possible as 16mm is the largest in this series. Keep in mind a plain PB cylinder drifts when air pressure is lost, so applications requiring fail-safe holding need an external rod lock.
To order, confirm the 16mm bore, 225mm stroke, M5x0.8 porting, and the R axial back cover. The Ø5 mm piston rod uses an M10x1.0 end thread for load coupling. Over this 225mm stroke, the slender rod is built strictly for coaxial thrust, so any off-axis loading mandates an external linear guide 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 PB16X225R FAQ
At 0.5 MPa this 16mm bore cylinder outputs 100.5 N push and 90.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
The R suffix denotes an axial air inlet for straight in-line plumbing. End-of-stroke deceleration is handled by a fixed TPU bumper rather than an adjustable air cushion, meaning it cannot be tuned externally. For high-mass loads at high speeds, you should meter-out the exhaust or install an external shock absorber.
