Airtac PB Pen-type Cylinder PB16X200SR
The AirTAC Airtac PB Pen-type Cylinder PB16X200SR 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 PB16X200SR
The AirTAC PB16X200SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to resist damp or mildly corrosive environments while saving critical space on end-of-arm tooling. This specific configuration includes an integrated piston magnet (S) for position sensing and an R axial air inlet for straightforward in-line plumbing via the M5x0.8 port.
Because this model features a 200 mm stroke, the slender Ø5 mm rod requires careful alignment to prevent side-loading damage; utilizing an external linear bearing ensures smooth coaxial thrust over the extended travel. The end caps incorporate a fixed TPU bumper at each end to decelerate the piston, which is not field-adjustable. For high-speed cycling with heavy tooling mass, metering out the exhaust or adding an external shock absorber is strongly recommended to prevent the bumpers from bottoming out.

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 PB16X200SR Is Used
PCB Depaneling Router
Drives a low-profile cutting head along a 200 mm path to separate printed circuit boards, utilizing the 100.5 N push force to maintain steady feed rates against router resistance.
Package Divert Arm
Extends a lightweight deflector flap on a sorting line to reroute small cartons, relying on the R axial inlet for flush mounting against the conveyor frame.
Textile Yarn Guide
Shifts a thread guide carriage back and forth across a 200 mm span, where the SUS304 stainless barrel withstands humid dyeing environments and high cycle speeds.
Is the Airtac PB Pen-type Cylinder PB16X200SR the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø12 bore (56.5 N push at 0.5 MPa) for lighter gripping tasks, or recognize that the Ø16 represents the maximum standard push force in this family at 100.5 N. A practical safe working load is approximately 60 N, which accounts for seal friction and ensures smooth travel. For vertical lifting applications, plan to hoist about 5.1 kg of real part weight to maintain a sane 2:1 safety margin at 0.5 MPa. If your process requires the piston to stay put when air pressure drops or the valve centers, note that this cylinder will drift; an external rod lock or mechanical stop is required for fail-safe holding.
Confirm your ordering essentials before checkout: 16 mm bore, 200 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the R axial back cover inlet. The rod-end thread is M10x1.0 for secure load coupling.
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 PB16X200SR 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 force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
No, a plain PB-type cylinder does not hold its position when air is lost or the valve is centered; the piston will drift. The fixed TPU bumpers only decelerate the piston near the stroke ends and do not act as a lock. An external stop or rod lock is required for fail-safe holding.
