Airtac PB Pen-type Cylinder PB16X205SU
The AirTAC Airtac PB Pen-type Cylinder PB16X205SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 205mm 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 PB16X205SU
The AirTAC PB16X205SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 205mm stroke, generating 100.5 N of push force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This configuration includes a built-in piston magnet for position sensing.
Air connects via an M5x0.8 port, and this specific variant uses a U-type back cover for a 90-degree perpendicular side inlet, allowing flat plumbing in restricted spaces. Because the stroke is relatively long and the rod is only Ø5 mm, maintaining coaxial alignment is critical to prevent side loading. The cylinder relies on a fixed TPU bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| Stroke | 205 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 PB16X205SU Is Used
PCB Depaneling Router
Drives a lightweight cutting head along a 205mm path to singulate printed circuit boards, utilizing the slim stainless body to fit within dense electronics manufacturing machinery.
Pouch Sealing Clamp
Applies up to 60 N of safe clamping force to hold flexible packaging materials under a heat bar, with the U side inlet keeping air lines flat against the machine frame.
Parcel Sorting Diverter
Pushes small parcels off a high-speed belt using fast 50-800 mm/s travel, where the fixed TPU bumpers absorb the repetitive impact of mid-stroke energy.
Is the Airtac PB Pen-type Cylinder PB16X205SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N (roughly 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. For vertical lifts, this translates to safely raising around 5.1 kg with a 2:1 safety margin. If your application requires less force, the adjacent Ø12 bore offers 56.5 N push at 0.5 MPa; stepping up is not possible as Ø16 is the largest in this series.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required to hold a load securely. To order, confirm the 16mm bore, 205mm stroke, M5x0.8 porting, the S magnet for reed or electronic switches, and the U 90-degree side 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 PB16X205SU FAQ
This 16mm bore double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it provides 140.7 N push and 126.9 N pull. It operates on filtered air at 0.15-0.7 MPa with speeds of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of stroke and does not act as a brake. You must add an external rod lock or mechanical stop to hold a load safely.
