Airtac PB Pen-type Cylinder PB16X135SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X135SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 135mm 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 PB16X135SCB
The AirTAC PB16X135SCB is a double-acting JIS pen-size mini cylinder engineered for compact automation. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 5 mm rod to fit tight jig spaces. The integrated -S piston magnet enables position detection using an AirTAC reed or electronic switch.
This 16 mm bore variant features an M5x0.8 air port and a CB double clevis back cover, allowing the body to pivot smoothly with the load. It relies on fixed TPU bumpers at both ends to decelerate motion over the final few millimeters. Because the 135 mm stroke is substantial for a 5 mm rod, maintaining coaxial thrust is critical to prevent deflection and premature seal 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 PB16X135SCB Is Used
PCB Depaneling Routing
Pivots a router head via the CB clevis to singulate printed circuit boards, utilizing the 100.5 N push force to maintain steady feed pressure against the material.
Carton Flap Folding
Drives a lightweight mechanical arm to tuck corrugated box flaps prior to sealing, where the slim stainless body resists humid packing line environments.
Small Parts Elevation
Lifts delicate electronic connectors weighing up to 5.1 kg in a vertical transfer station, relying on the fixed TPU bumper to soften the end-of-stroke impact.
Is the Airtac PB Pen-type Cylinder PB16X135SCB the Right Cylinder?
This 16 mm bore provides the highest standard force in the PB family, pushing 100.5 N at 0.5 MPa. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push force, which is often sufficient for lighter actuators. Since this is the largest standard pen-size option, there is no larger bore available in this specific series.
When sizing your load, plan for a safe working capacity of roughly 60 N, which accounts for seal friction at 0.5 MPa. For vertical lifts, this equates to safely raising about 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 135 mm stroke, M5x0.8 port, S magnet, and CB double clevis mount. Note that a plain PB cylinder will drift and cannot hold a vertical load if air pressure is lost, requiring an external rod lock for fail-safe positioning.
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 PB16X135SCB 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 force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The CB suffix denotes a double clevis back cover, allowing the cylinder body to pivot during operation. Instead of an adjustable air cushion, it uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters. If moving heavy tooling at high speed, you should meter-out the exhaust or add an external shock absorber.
