Airtac PB Pen-type Cylinder PB16X185SR
The AirTAC Airtac PB Pen-type Cylinder PB16X185SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 185mm 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 PB16X185SR
The AirTAC PB16X185SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and a 5 mm piston rod, providing 100.5 N of push force at 0.5 MPa. The integrated R axial inlet allows for clean in-line plumbing, while the built-in magnet enables position detection.
Designed for tight jigs and light end-of-arm tooling, this 16 mm bore unit operates at speeds from 50-800 mm/s. It relies on a fixed TPU bumper at each end to decelerate the stroke, which is not field-adjustable. Because the rod is only 5 mm thick, maintaining coaxial alignment is critical to prevent side-load damage over the 185 mm travel.

| Rod diameter | Ø5 mm |
| Stroke | 185 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 |
| Cushion | Elastic bumper (both 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 PB16X185SR Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics depaneling machine, where the slim stainless body resists flux residue and the 100.5 N thrust cleanly scores separation lines.
Carton Flap Folder
Tucks minor flaps on a compact packaging conveyor, using the 185 mm stroke to clear varying box widths while the R axial inlet keeps plumbing flush against the machine frame.
Lab Sample Dispenser
Drives a pipette plunger for automated fluid handling, relying on the S magnet to trigger reed or electronic switches for precise volumetric dosing.
Is the Airtac PB Pen-type Cylinder PB16X185SR the Right Cylinder?
When sizing this model, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa, while the Ø16 provides 100.5 N. Plan for a safe working load of about 60 N, which is roughly 60% of the 0.5 MPa theoretical force, to account for seal friction and smooth travel. This equates to lifting about 5.1 kg vertically with a sane 2:1 margin.
Confirm your ordering essentials: 16 mm bore, 185 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and R axial back cover. Note that a plain PB-type does not hold its load if air is lost or the valve is centred; the piston drifts and the bumper only decelerates near stroke end. For a fail-safe hold, specify an external stop or rod lock.
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 PB16X185SR FAQ
This double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa, with a maximum push of 140.7 N and pull of 126.9 N at 0.7 MPa. Operating pressure ranges from 0.15-0.7 MPa, and it travels at 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so at high speeds with real mass you should meter-out the exhaust or add an external shock absorber. It does not hold position on air loss, requiring an external rod lock for fail-safe load holding.
