Airtac PB Pen-type Cylinder PB16X250SU
The AirTAC Airtac PB Pen-type Cylinder PB16X250SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 250mm 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 PB16X250SU
The AirTAC PB16X250SU is a double-acting JIS pen-size 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. The U suffix equips the rear cover with a 90-degree perpendicular air inlet, keeping your pneumatic plumbing flat against the machine frame.
This model includes a built-in piston magnet (S) for position detection using AirTAC reed or electronic switches. Operating at speeds up to 800 mm/s, it relies on a fixed TPU bumper at each end to absorb impact. Because the 250 mm stroke is substantial for a 5 mm rod, maintaining coaxial thrust is critical to prevent deflection.

| 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 PB16X250SU Is Used
Package Flap Folding
Drives a lightweight folding arm on a carton sealing line, using the 90-degree side inlet to keep plumbing flush within the narrow conveyor frame.
PCB Test Socket Actuation
Applies the 100.5 N push force to lower a test probe onto printed circuit boards, relying on the magnetic sensor for precise position confirmation.
Small Parts Vertical Lift
Raises delicate electronic components weighing under 5 kg, requiring an external linear guide to support the 5 mm rod over the 250 mm extension.
Is the Airtac PB Pen-type Cylinder PB16X250SU the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N of push force at 0.5 MPa, offering a safe working load of roughly 60 N for smooth travel. If you need less force, the 12 mm bore provides 56.5 N; stepping up is not required as this is the largest standard diameter in the PB family. Plan for a vertical lift capacity of about 5.1 kg with a 2:1 safety margin.
Confirm your ordering essentials: 16 mm bore, 250 mm stroke, M5x0.8 port, built-in magnet (S), and the U 90-degree side inlet. Note that a plain PB cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required to hold a load safely in place.
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 PB16X250SU 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 operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
It uses a fixed TPU bumper at both ends to decelerate the piston over the last few millimeters, which is not adjustable or field-tunable. For high-speed cycles with heavy tooling, meter-out the exhaust or add an external shock absorber. The built-in magnet allows tracking by AirTAC reed or electronic switches.
