Airtac PB Pen-type Cylinder PB16X70SR
The AirTAC Airtac PB Pen-type Cylinder PB16X70SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 70mm 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 PB16X70SR
The AirTAC PB16X70SR is a JIS pen-size double-acting single-rod cylinder, delivering 100.5 N of push and 90.7 N of pull at 0.5 MPa. Its slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while saving valuable space on tight jigs. Equipped with an R axial inlet, it supports in-line plumbing for neat routing.
This 16 mm bore unit features a built-in S magnet for position detection using AirTAC reed or electronic switches. It uses M5x0.8 ports and an M10x1.0 rod-end thread. Because it relies on a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling high tooling masses at speed.

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 PB16X70SR Is Used
PCB Depaneling Router
Actuates a cutting head fixture on an electronics assembly line, utilizing the 100.5 N extend force to cleanly separate routed circuit boards.
Carton Flap Folder
Tucks minor flaps on a compact packaging conveyor, where the slim stainless body resists washdown moisture and fits within tight side guides.
Lightweight Parts Elevator
Pushes small plastic trays up a 70 mm vertical lift, safely moving components weighing up to 5.1 kg with a proper 2:1 load margin.
Is the Airtac PB Pen-type Cylinder PB16X70SR the Right Cylinder?
If you need slightly less force, the 12 mm bore provides 56.5 N push at 0.5 MPa; stepping up is not an option as 16 mm is the largest in this family. For the PB16X70SR, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. This equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin. Keep in mind the thin Ø5 mm rod is designed for coaxial thrust, so over this 70 mm stroke add an external guide if you have off-axis loads. Confirm your ordering essentials: 16 mm bore, 70 mm stroke, M5x0.8 port, S magnet, R axial cover, and any LB/FA/CJ bracket. Note that a plain PB cylinder will drift and cannot hold a load if air pressure is lost or the valve is centred; an external rod lock is required 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 PB16X70SR 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 speed of 50-800 mm/s.
No, a plain PB cylinder drifts if air is lost or the valve is centred. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a brake. For fail-safe vertical holding, you must install an external rod lock or mechanical stop.
