Airtac PB Pen-type Cylinder PB16X175SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X175SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 175mm 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 PB16X175SCB
The AirTAC PB16X175SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, it provides robust actuation for its footprint.
This specific configuration includes an integrated piston magnet for position sensing and a CB double clevis back cover for pivoting loads. Fluid is filtered air (40 µm), operating pressure ranges from 0.15 to 0.7 MPa, and the M5x0.8 air ports support speeds from 50 to 800 mm/s. It relies on a fixed TPU bumper at each end to decelerate the stroke, rather than an adjustable air cushion.

| 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 |

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 PB16X175SCB Is Used
Pivoting Gripper Arms
Drives small robotic gripper assemblies where the CB double clevis accommodates angular movement during component pick-and-place operations.
Carton Flap Folding
Executes fast, repetitive folding motions on packaging lines, utilizing the 100.5 N extend force to tuck flaps securely at high cycle rates.
Lab Sample Sorting
Actuates diverters on diagnostic analyzers, benefiting from the SUS304 build to resist humidity and chemical wipe-downs in clinical settings.
Is the Airtac PB Pen-type Cylinder PB16X175SCB the Right Cylinder?
Selecting this 16 mm bore model gives you 100.5 N push at 0.5 MPa. If you need slightly less force, stepping down to the 12 mm bore yields 56.5 N push, while moving up is not an option as 16 mm is the largest available in this series. For practical sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa rating) to account for seal friction, or expect to vertically lift around 5.1 kg with a sane 2:1 safety margin.
Because this is a 175 mm stroke unit, the slender Ø5 mm piston rod requires external guiding to prevent side-loading damage. Keep in mind that a plain cylinder drifts when air is lost or the valve is centered; the bumpers only decelerate near the end of travel and will not hold a load, so an external rod lock is necessary for fail-safe positioning. Confirm your ordering essentials: 16 mm bore, 175 mm stroke, M5x0.8 port, S magnet, and CB double clevis.
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 PB16X175SCB 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
The -S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position detection. Cushioning is handled by a fixed TPU bumper at each end that decelerates the last few millimeters of travel; it is not adjustable, so at high speeds with heavy tooling mass you should meter-out the exhaust or add an external shock absorber.
