Airtac PB Pen-type Cylinder PB16X175SR
The AirTAC Airtac PB Pen-type Cylinder PB16X175SR 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 PB16X175SR
The AirTAC PB16X175SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It provides a robust 100.5 N push and 90.7 N pull at 0.5 MPa, scaling up to a maximum 140.7 N push at 0.7 MPa. The slim SUS304 stainless barrel and screwed-in covers keep weight down for end-of-arm tooling, while the M5x0.8 port and M10x1.0 rod-end thread handle standard pneumatic plumbing. An integrated R axial inlet keeps air lines perfectly in-line with the body.
Because this unit carries the S option, a built-in piston magnet enables position detection using AirTAC reed or electronic switches. Travel is capped by a fixed TPU bumper at each end rather than an adjustable air cushion, meaning it only decelerates the final few millimeters of the 175 mm stroke. For rapid cycling with heavy tooling, metering out the exhaust or adding an external shock absorber prevents the bumper from bottoming out.

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 PB16X175SR Is Used
PCB Depaneling Router
Drives a high-speed cutting head along a 175 mm path to singulate printed circuit boards, utilizing the stainless body to resist flux residue and coolant mists.
Carton Flap Folder
Extends to tuck minor flaps on small pharmaceutical cartons, relying on the 100.5 N push force at 0.5 MPa to overcome light cardboard resistance.
Pick-and-Place Z-Axis
Acts as a vertical stroke for an end-of-arm vacuum gripper moving electronic chips, where the S magnet triggers an electronic switch to confirm grip height.
Is the Airtac PB Pen-type Cylinder PB16X175SR the Right Cylinder?
This 16 mm bore strikes the top of the PB family range, stepping up from the 12 mm option which yields 56.5 N push at 0.5 MPa. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N rated push at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift scenarios, this equates to lifting about 5.1 kg safely with a 2:1 margin. Keep in mind the thin Ø5 mm rod is designed strictly for coaxial thrust; over the 175 mm stroke, any off-axis load requires an external linear bearing to prevent binding.
When air pressure drops or the valve centers, this cylinder will drift and cannot hold a load—the end bumpers only decelerate impact near stroke end, so an external rod lock is necessary for fail-safe holding. To finalize your build, confirm the 16 mm bore, 175 mm stroke, M5x0.8 port, S magnet for sensors, and R axial inlet 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 PB16X175SR 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 cylinder operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; this is not an adjustable air cushion, so high-speed loads may need external shock absorption. The S designation means it has a built-in magnet compatible with AirTAC reed or electronic switches for precise end-of-stroke detection.
