Airtac PB Pen-type Cylinder PB16X80SR
The AirTAC Airtac PB Pen-type Cylinder PB16X80SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 80mm 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 PB16X80SR
The AirTAC PB16X80SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 16mm bore and an 80mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while keeping end-of-arm tooling weight to an absolute minimum.
This specific configuration includes an R axial air inlet for in-line plumbing and a built-in S magnet for position sensing. The Ø6-Ø16 bore range utilizes a fixed TPU bumper at each end to decelerate the piston over the final few millimeters of travel. Because the rod end features an M10x1.0 thread and a 5mm diameter, maintaining coaxial alignment is critical to prevent side loading and premature wear.

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 PB16X80SR Is Used
PCB Depaneling Router
Drives a low-friction cutting head along an 80mm path to singulate printed circuit boards, utilizing the slim stainless body to fit within dense electronics manufacturing machinery.
Blister Pack Sealing Jig
Applies up to 140.7 N of clamping force at 0.7 MPa to hold thin plastic blister packs against a heat seal platen, with the S magnet confirming the closed position via a reed or electronic switch.
Package Divert Gate
Actuates a lightweight routing flap on a conveyor line to sort small parcels, relying on the R axial inlet for streamlined in-line pneumatic plumbing along the conveyor frame.
Is the Airtac PB Pen-type Cylinder PB16X80SR the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction by loading the cylinder to about 60% of its 100.5 N theoretical push at 0.5 MPa. For vertical lifts, this equates to raising approximately 5.1 kg safely with a 2:1 margin. If you need slightly less force, the 12mm bore provides 56.5 N push at 0.5 MPa; stepping up is not possible as 16mm is the largest standard diameter in this family. Confirm your ordering essentials: 16mm bore, 80mm stroke, M5x0.8 port, S magnet, and R axial inlet.
Note that a plain PB cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. For fail-safe load holding, an external stop or rod lock is required. Additionally, the fixed TPU bumper is not adjustable, so if you are moving real tooling mass at higher speeds within the 50-800 mm/s range, you should meter-out the exhaust or add an external shock absorber to prevent bottoming out.
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 PB16X80SR FAQ
This double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates on filtered air at 0.15-0.7 MPa with speeds of 50-800 mm/s.
No, a plain PB cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a lock. For vertical loads, you must add an external rod lock or mechanical stop.
