Airtac PB Pen-type Cylinder PB16X15R
The AirTAC Airtac PB Pen-type Cylinder PB16X15R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 15mm 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 PB16X15R
The AirTAC PB16X15R is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, making it the highest force class in this slim round-body family. The Ø16 mm barrel and piston rod are SUS304 stainless, providing durable resistance in damp or mildly corrosive work areas without adding bulk.
This specific configuration features a 15 mm stroke and an R axial air inlet for in-line plumbing via an M5x0.8 port. It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel rather than a field-adjustable cushion. Because the rod is a slender Ø5 mm threaded M10x1.0, it is built for coaxial thrust and requires an external guide if subjected to off-axis loads.

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 PB16X15R Is Used
PCB Depanelling Jig
Drives a low-profile cutting blade on an electronics assembly line, utilizing the 15 mm stroke and 100.5 N push to cleanly separate routed circuit boards without stressing adjacent components.
Carton Flap Tucker
Folds small corrugated box flaps prior to sealing on a compact packaging conveyor, where the slim 16 mm pen-size body fits neatly between guide rails and the SUS304 barrel resists humid washdown environments.
Light Part Ejector
Pushes molded plastic parts out of a tight injection mold cavity, using the M10x1.0 rod end thread to secure a custom ejector pin while relying on the R axial inlet to keep plumbing flush against the machine frame.
Is the Airtac PB Pen-type Cylinder PB16X15R the Right Cylinder?
Selecting this 16 mm bore provides the maximum thrust available in the PB series, stepping up from the 12 mm bore which offers 56.5 N push at 0.5 MPa. If your application requires even less force to save space, the 10 mm bore provides 39.3 N push. For this PB16X15R model, confirm your ordering essentials: 16 mm bore, 15 mm stroke, M5x0.8 port, no sensor magnet, and the R axial back cover inlet. A plain double-acting cylinder like this does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external stop or rod lock is required for fail-safe holding.
When sizing your payload, plan for a safe working load of about 60 N, which is roughly 60% of the 100.5 N theoretical push at 0.5 MPa to account for seal friction. This equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin. The fixed TPU bumper only absorbs impact near the stroke ends, so for higher cycle speeds with heavy tooling mass, meter-out the exhaust or install an external shock absorber.
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 PB16X15R 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.
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, so add an external shock absorber for high-energy loads. Additionally, it does not hold its load if air is lost, as the bumper is not a brake or lock.
