Airtac PB Pen-type Cylinder PB16X15CB
The AirTAC Airtac PB Pen-type Cylinder PB16X15CB 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 PB16X15CB
The AirTAC PB16X15CB is a JIS double-acting single-rod pen-size mini cylinder engineered for short, fast linear motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, making it the highest force class in this compact family. The CB suffix equips the rear cover with a double clevis, allowing the body to pivot freely on articulated linkages.
Built with a SUS304 stainless steel piston rod and barrel, the unit resists moisture and mild corrosion in washdown or humid production zones. Air connects via an M5x0.8 port, while the Ø5 mm rod terminates in an M10x1.0 thread for secure load coupling. Travel is governed by a fixed TPU bumper at each end rather than an adjustable air cushion, efficiently absorbing impact over this brief 15 mm stroke.

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 PB16X15CB Is Used
Package Diverter Flap
Pivots a sorting gate on a packaging conveyor to redirect small cartons into secondary lanes using the integrated double clevis mount.
PCB Edge Pinning Jig
Drives a short 15 mm stroke to push locating pins against circuit boards during automated soldering or inspection cycles.
Film Clamp Arm
Actuates a pivoting tension arm on a wrapping machine, holding polymer film taut before the heat sealing head descends.
Is the Airtac PB Pen-type Cylinder PB16X15CB the Right Cylinder?
Selecting this 16 mm bore yields the strongest thrust available in the PB lineup, pushing 100.5 N at 0.5 MPa. If your fixture requires less force, stepping down to the 12 mm bore drops the push to 56.5 N, offering a lighter footprint; there is no larger standard bore above this in the series. For this specific CB variant, ensure your design accommodates the double clevis pivot and order the matching pin. Because the rod is only Ø5 mm, maintain coaxial alignment to prevent side loading.
When sizing the workload, plan for approximately 60 N of real work at 0.5 MPa, which accounts for a safe 60 percent loading margin against seal friction. In a vertical lift scenario, this equates to raising about 5.1 kg safely with a 2:1 dynamic margin. Note that a plain cylinder drifts when air pressure is removed or the valve centers, so an external rod lock is necessary for fail-safe holding.
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 PB16X15CB FAQ
This double-acting cylinder generates 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 140.7 N push and 126.9 N pull. It operates between 0.15 and 0.7 MPa at speeds of 50-800 mm/s.
The CB designation adds a rear double clevis, allowing the cylinder to swing naturally with articulated mechanisms. End-of-stroke deceleration relies on fixed TPU bumpers rather than adjustable air cushions; for heavy tooling mass at high speeds, meter-out the exhaust or add an external shock absorber.
