Airtac PB Pen-type Cylinder PB16X25R
The AirTAC Airtac PB Pen-type Cylinder PB16X25R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 25mm 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 PB16X25R
The AirTAC PB16X25R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 16 mm bore and a 25 mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide corrosion resistance for damp or mildly wet production lines, keeping end-of-arm tooling lightweight.
This specific configuration uses an R axial air inlet for in-line plumbing and an M5x0.8 port. The Ø5 mm piston rod has an M10x1.0 rod-end thread for secure load coupling. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling high tooling masses at speed.

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 PB16X25R Is Used
PCB Depaneling Router
Provides the precise 100.5 N thrust to plunge a cutting bit into printed circuit boards, utilizing the slim pen-size profile to fit between dense routing fixtures.
Carton Flap Folder
Actuates a lightweight arm to tuck minor flaps on small product boxes, taking advantage of the 50-800 mm/s speed range and fixed TPU bumpers to handle rapid cycling.
Small Parts Lift Station
Elevates delicate plastic components between conveyor tiers, where the SUS304 build resists humid factory environments and the R axial inlet keeps plumbing flat against the machine frame.
Is the Airtac PB Pen-type Cylinder PB16X25R the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, which accounts for seal friction and smooth travel. If you need to lift vertically, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If your application requires slightly less force, stepping down to the Ø12 bore yields 56.5 N of push at 0.5 MPa; if you need more power, this Ø16 is the largest available in the family.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered, so an external rod lock is required for fail-safe holding. To order, confirm the 16 mm bore, 25 mm stroke, R axial inlet, and the absence of a sensor magnet. The thin Ø5 mm rod is built for coaxial thrust, so avoid side loading or add a linear bearing for off-axis loads.
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 PB16X25R 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
The R suffix indicates a back cover with an axial air inlet for in-line plumbing. It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel. This bumper is not adjustable and does not act as a brake, so for heavy or high-speed loads, you should add an external shock absorber.
