Airtac PB Pen-type Cylinder PB16X40SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X40SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 40mm 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 PB16X40SCB
The AirTAC PB16X40SCB is a JIS pen-size double-acting single-rod 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 to a maximum 140.7 N push at 0.7 MPa. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position sensing with AirTAC reed or electronic switches, and a CB double clevis back cover for pivoting loads. Air plumbing connects via an M5x0.8 port, and the Ø5 mm rod features an M10x1.0 end thread. Deceleration is handled by a fixed TPU bumper at each end, which is not field-adjustable.

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 PB16X40SCB Is Used
Pivoting Clamp Arm
Ideal for swinging a small machining fixture thanks to the CB double clevis, utilizing the 100.5 N push force to secure light aluminum parts during drilling.
Diverter Gate Actuation
Drives a lightweight sorting flap on a packaging line, where the SUS304 stainless body withstands washdown and the compact pen-size profile fits between conveyor belts.
EOAT Vertical Lift
Mounts on a robot arm to raise small electronic components, safely lifting a 5.1 kg payload vertically while the S magnet confirms the 40 mm stroke endpoint.
Is the Airtac PB Pen-type Cylinder PB16X40SCB the Right Cylinder?
When sizing this 16 mm bore unit, stepping down to a 12 mm bore drops the 0.5 MPa push to 56.5 N, while this PB16X40SCB provides 100.5 N. As the largest standard diameter in the PB family, it offers the peak thrust of 140.7 N at 0.7 MPa. For practical sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa figure) to account for seal friction. This equates to lifting a 5.1 kg mass vertically with a sane 2:1 safety margin.
Confirm your ordering essentials: 16 mm bore, 40 mm stroke, M5x0.8 port, S magnet, and CB double clevis. Note that a plain PB cylinder drifts when air is lost or the valve is centered, as the fixed TPU bumper only decelerates near stroke end rather than locking the load. For fail-safe holding, an external rod lock or stop is required. Additionally, the Ø5 mm rod is designed for coaxial thrust, so add an external linear bearing if your application involves off-axis loads.
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 PB16X40SCB 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 at speeds of 50-800 mm/s.
The CB back cover provides a double clevis joint, allowing the cylinder to pivot smoothly on a pin mount. At stroke endpoints, a fixed TPU bumper decelerates the piston over the last few millimeters. Because this bumper is not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high speeds.
