Airtac PB Pen-type Cylinder PB6X45R
The AirTAC Airtac PB Pen-type Cylinder PB6X45R is a double-acting pen-size (mini) air cylinder with a Ø6mm bore and 45mm 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 PB6X45R
The AirTAC PB6X45R is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It delivers 14.2 N of push force and 10.6 N of pull force at 0.5 MPa. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments, keeping end-of-arm tooling weight to an absolute minimum.
This 45 mm stroke unit features an R axial air inlet for in-line plumbing and an M5x0.8 port. It relies on a fixed TPU bumper at each end to decelerate the stroke over the final few millimeters. Because the bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher speeds.

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 (Ø6mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 14.2 N | 10.6 N |
| 0.7 MPa (max) | 19.8 N | 14.8 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 PB6X45R Is Used
PCB Pick-and-Place
Drives a small vacuum nozzle on a pick-and-place head to lift delicate electronic components, utilizing the lightweight stainless body to minimize robotic arm inertia.
Blister Pack Sorting
Pushes lightweight pharmaceutical blister packs into a sorting chute, where the compact 6 mm barrel fits neatly between tight guide rails without binding.
Lab Dispenser Actuation
Toggles a micro-valve on an automated fluid dispensing station, benefiting from the fast 50-800 mm/s cycle speed and precise in-line axial porting.
Is the Airtac PB Pen-type Cylinder PB6X45R the Right Cylinder?
When sizing this 6 mm bore class, stepping down to a 4 mm bore yields 6.3 N of push at 0.5 MPa, while stepping up to a 10 mm bore provides 39.3 N. For the PB6X45R, plan for a safe working load of roughly 9 N at 0.5 MPa, which accounts for seal friction and smooth travel. In a vertical lift scenario with a sane 2:1 safety margin, this equates to lifting about 0.7 kg. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; an external rod lock is required for fail-safe holding.
Confirm your ordering essentials: 6 mm bore, 45 mm stroke, M5x0.8 port, no sensor magnet, and the R axial inlet configuration. The Ø3 mm piston rod utilizes an M5x0.8 rod-end thread for load coupling. Since the rod is slender and built strictly for coaxial thrust, avoid side loading and add an external linear bearing if guiding off-axis loads over the 45 mm travel.
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 PB6X45R FAQ
At 0.5 MPa, the push (extend) force is 14.2 N and the pull (retract) force is 10.6 N. At the maximum operating pressure of 0.7 MPa, the push force is 19.8 N and the pull force is 14.8 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 to decelerate the piston over the last few millimeters, which is not field-adjustable or capable of locking the load. If air pressure is lost, the piston will drift, so an external stop or rod lock is needed for fail-safe holding. The bumper alone cannot absorb high-energy impacts without metering out the exhaust.
