Airtac PB Pen-type Cylinder PB16X200R
The AirTAC Airtac PB Pen-type Cylinder PB16X200R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 200mm 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 PB16X200R
The AirTAC PB16X200R is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 200mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, peaking at 140.7 N extend force when supplied at the 0.7 MPa maximum operating pressure. The R suffix specifies an axial air inlet for clean in-line plumbing via the fixed M5x0.8 port.
Constructed with a SUS304 stainless steel barrel and piston rod, this slim round body resists damp and mildly corrosive industrial environments. It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because the 200mm stroke amplifies the slenderness of the Ø5 mm rod, you should add an external linear bearing for off-axis loads to keep the thrust perfectly coaxial.

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 PB16X200R Is Used
PCB Depaneling Router
Drives a light cutting head along a 200mm path to singulate printed circuit boards, utilizing the 100.5 N push force to maintain steady feed against router bit resistance.
Package Flap Tucking
Extends a small paddle to fold cardboard flaps on a carton sealing line, where the fast 50-800 mm/s speed and axial R inlet keep pneumatic plumbing tightly routed.
Lab Sample Dispenser
Actuates a pipette or valve assembly over a 200mm stroke for fluid dispensing, benefiting from the SUS304 stainless build in damp or wash-down laboratory settings.
Is the Airtac PB Pen-type Cylinder PB16X200R the Right Cylinder?
When sizing this 16mm bore actuator, stepping down to a 12mm bore drops the 0.5 MPa push force to 56.5 N, while stepping up is not an option as this is the largest diameter in the PB family. For practical sizing at 0.5 MPa, plan for a safe working load of about 60 N (roughly 60% of the theoretical 100.5 N figure) to account for seal friction and smooth travel. In vertical lift scenarios, this translates to lifting about 5.1 kg safely with a 2:1 margin.
Remember that a plain PB cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load. If your application must hold position without live pressure, specify an external stop or rod lock. To order, confirm the 16mm bore, 200mm stroke, M5x0.8 port, no magnet, and the R axial inlet back cover.
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 PB16X200R FAQ
At 0.5 MPa, the push (extend) force is 100.5 N and the pull (retract) 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.
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. If you move heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber. Additionally, it does not hold its load if air is lost, so an external rod lock is required for fail-safe positioning.
