Airtac PB Pen-type Cylinder PB16X70SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X70SCB 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 PB16X70SCB
The AirTAC PB16X70SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and a 5 mm piston rod with an M10x1.0 rod-end thread. The integrated -S piston magnet enables position detection using AirTAC reed or electronic switches.
This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin to accommodate lateral misalignment during the stroke. Air connections are made via M5x0.8 ports, and end-of-stroke energy is managed by fixed TPU bumpers rather than adjustable air cushions. Because the rod is only 5 mm thick, it is designed for coaxial thrust; over this 70 mm stroke, adding an external guide or linear bearing helps prevent binding if the payload is off-axis.

| Stroke | 70 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

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 PB16X70SCB Is Used
PCB Depaneling Router
Actuates a cutting head or clamping fixture on an electronics assembly line, where the 100.5 N extend force securely holds panels and the SUS304 body resists fiberglass dust.
Pouch Sealing Jaw
Drives a pivoting sealing jaw on a vertical form-fill-seal machine, using the CB clevis to swing the mechanism while providing consistent 90.7 N retract tension at 0.5 MPa.
Sorting Diverter Arm
Pushes lightweight parcels off a logistics conveyor belt, relying on the 50-800 mm/s speed range and fixed TPU bumpers to absorb the impact of rapid direction changes.
Is the Airtac PB Pen-type Cylinder PB16X70SCB the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N of theoretical push at 0.5 MPa, though good practice targets a safe working load of about 60 N to account for seal friction and smooth travel. If you need to step down, the 12 mm bore provides 56.5 N of push, while stepping up is not an option as 16 mm is the largest in this series. Vertically lifting a part, you can expect to raise about 5.1 kg safely with a 2:1 margin.
When ordering, confirm the 70 mm stroke, the M5x0.8 port size, the built-in -S magnet for sensors, and the CB double clevis mount. Note that a plain double-acting cylinder drifts when air is lost or the valve is centered, so an external rod lock or mechanical stop is required if the payload must be held in place during a failure.
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 PB16X70SCB 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 at 0.15-0.7 MPa with a speed range of 50-800 mm/s, an M5x0.8 port, and an M10x1.0 rod-end thread.
The CB suffix denotes a double clevis back cover that allows the cylinder body to pivot on a mounting pin, which is ideal for articulating linkages. Instead of adjustable air cushions, it uses fixed TPU elastic bumpers at both ends to decelerate the piston over the last few millimeters; for heavy tooling mass at high speeds, you should meter-out the exhaust or add an external shock absorber.
