Airtac PB Pen-type Cylinder PB16X225SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X225SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 225mm 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 PB16X225SCB
The AirTAC PB16X225SCB 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, scaling up to 140.7 N push at its 0.7 MPa maximum. The SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping the unit slim enough for tight jig spaces and light end-of-arm tooling.
This specific configuration includes a built-in piston magnet for position sensing with AirTAC reed or electronic switches, plus a CB double clevis back cover for pivoting loads. Air connects via an M5x0.8 port. Because the stroke runs 225 mm on a Ø5 mm rod, maintaining coaxial alignment is critical to prevent side-load wear. The end caps use a fixed TPU bumper to decelerate the piston over the final few millimeters, which may require external shock absorption if cycling rapidly with heavy tooling.

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 PB16X225SCB Is Used
Pivoting Component Diverter
Ideal for swinging lightweight aluminum brackets on a packaging conveyor, utilizing the CB double clevis to accommodate the angular motion while pushing with 100.5 N at 0.5 MPa.
Textile Loom Tensioner
Suitable for damp textile manufacturing environments where the SUS304 stainless body resists moisture, providing fast 50-800 mm/s actuation to maintain thread tension via a pivoting lever arm.
Lab Sample Sorting Gate
Deploys reliably in compact laboratory automation, using the built-in S magnet with electronic switches to confirm gate position while handling small vial racks over the 225 mm travel.
Is the Airtac PB Pen-type Cylinder PB16X225SCB the Right Cylinder?
When sizing this actuator, note that the Ø16 bore produces 100.5 N push at 0.5 MPa. If you need less force, stepping down to the Ø12 bore yields 56.5 N push, while this Ø16 is the largest standard option in the PB pen-size family. Plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. For vertical lifts, this equates to lifting about 5.1 kg safely with a 2:1 margin.
Confirm your ordering essentials: 16 mm bore, 225 mm stroke, M5x0.8 port, S magnet for sensors, and CB double clevis mounting. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end and does not lock the load, so an external rod lock is required for fail-safe holding.
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 PB16X225SCB 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.
The CB back cover is a double clevis designed for pivoting mount applications. At stroke endpoints, a fixed TPU bumper decelerates the piston over the last few millimeters; it is not adjustable, so for high-speed cycles with heavy tooling you should meter-out the exhaust or add an external shock absorber.
