The AirTAC Airtac PB Pen-type Cylinder PB16X140SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 140mm 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.
The AirTAC PB16X140SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding bulk to your end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, it provides robust actuation for light machinery.
This 16mm bore unit uses an M5x0.8 air port and includes a U-type back cover for a 90-degree side inlet, keeping your plumbing flat against the machine frame. The integrated piston magnet supports AirTAC reed or electronic switches for position sensing. Operating at speeds up to 800 mm/s, it relies on a fixed TPU bumper at each end to decelerate the stroke.

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.
| 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.

Pushes a light carrier plate against a fixed fence on an electronics assembly line, utilizing the 90-degree side inlet to keep pneumatic hoses flush within a crowded electronics manufacturing cell.
Extends to fold cardboard flaps on pharmaceutical packaging equipment, where the fixed TPU bumper absorbs the end-of-stroke impact during continuous high-speed cycling.
Actuates a small lightweight deflector gate to route small plastic parts on a conveyor, relying on the built-in magnet to trigger an electronic switch for position confirmation.
When sizing this actuator, stepping down to a 12mm bore yields 56.5 N push at 0.5 MPa, while stepping up is not available as 16mm is the largest in this family. For the PB16X140SU, 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. Vertically, this translates to lifting about 5.1 kg with a sane 2:1 safety margin. Remember that a plain cylinder drifts when air is lost or the valve is centered; an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16mm bore, 140mm stroke, M5x0.8 port, S magnet, U side inlet, and no mounting bracket.
Quick checklist
This double-acting 16mm bore cylinder delivers a push force of 100.5 N and a pull force of 90.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push force is 140.7 N and the pull force is 126.9 N. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, a standard pen-size cylinder will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end; it does not act as a brake. For vertical loads requiring fail-safe holding, you must add an external stop or rod lock. Additionally, the thin 5mm rod is designed for coaxial thrust, so use an external guide for off-axis loads.
