Airtac PB Pen-type Cylinder PB16X35SR
The AirTAC Airtac PB Pen-type Cylinder PB16X35SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 35mm 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 PB16X35SR
The AirTAC PB16X35SR is a JIS double-acting single-rod mini cylinder engineered for compact, high-frequency tasks. It yields 100.5 N of push and 90.7 N of pull at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless barrel and piston rod provide dependable resistance in damp or mildly corrosive work areas, keeping end-of-arm tooling light.
This 16 mm bore unit features a 35 mm stroke and an M10x1.0 rod-end thread for secure load coupling. Because it carries the S option, a built-in piston magnet enables position detection using AirTAC reed or electronic switches. The R axial inlet supports clean in-line plumbing, while fixed TPU bumpers absorb impact at stroke ends.

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 PB16X35SR Is Used
PCB Depaneling Jig
Drives a lightweight cutting blade or clamping finger in tight electronics assembly cells where the 100.5 N extend force is sufficient and the slim body clears adjacent tooling.
Carton Flap Folder
Tucks small corrugated flaps on a packaging line, using the R axial inlet to keep pneumatic plumbing flush against the machine frame without protruding.
Lab Sample Sorter
Pushes vial racks into a testing carousel, benefiting from the SUS304 construction in humid laboratory environments and the S magnet for cycle counting.
Is the Airtac PB Pen-type Cylinder PB16X35SR the Right Cylinder?
When sizing this actuator, the Ø12 bore steps down with 56.5 N push, while there is no larger standard bore in this pen family, making 16 mm the maximum thrust tier. Plan for a safe working load of roughly 60 N, which is about 60 percent of the 0.5 MPa theoretical force, to account for seal friction. For vertical moves, this equates to lifting around 5.1 kg with a sensible 2:1 safety margin. Remember that a plain cylinder drifts when air is lost or the valve centers, so add an external rod lock if you need fail-safe holding. To order, confirm the 16 mm bore, 35 mm stroke, M5x0.8 port, S magnet, and R axial back cover.
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 PB16X35SR FAQ
At 0.5 MPa this 16 mm bore cylinder provides 100.5 N push and 90.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 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.
It uses fixed TPU bumpers at both ends to decelerate the last few millimeters of travel; these are not adjustable, so meter-out the exhaust or add an external shock absorber for heavy high-speed tooling. The built-in S magnet works with AirTAC reed or electronic switches for precise position detection.
