Airtac PB Pen-type Cylinder PB16X5SR
The AirTAC Airtac PB Pen-type Cylinder PB16X5SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 5mm 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 PB16X5SR
The AirTAC PB16X5SR is a double-acting JIS pen-size mini cylinder engineered for short-stroke, 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 while keeping weight low for end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, this 16 mm bore unit is both compact and powerful.
This specific configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet (S) for position sensing. Air enters via an M5x0.8 port, and the Ø5 mm piston rod features an M10x1.0 rod-end thread for secure load coupling. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling high tooling masses at speed.

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 PB16X5SR Is Used
Short-Stroke Clamping
Ideal for locking small electronic components into PCB routing fixtures, utilizing the 5 mm stroke to secure parts without overwhelming delicate surfaces.
Flap Deflection
Provides a rapid, compact tap to fold lightweight carton flaps on high-speed packaging lines, benefiting from the 50-800 mm/s travel speed.
Ejector Pins
Pushes small molded plastic parts out of shallow dies, where the 100.5 N thrust and short stroke deliver a precise, controlled ejection motion.
Is the Airtac PB Pen-type Cylinder PB16X5SR the Right Cylinder?
When sizing this model, the PB16X5SR provides 100.5 N push and 90.7 N pull at 0.5 MPa. If you need slightly less force, stepping down to the 12 mm bore yields 56.5 N of push, while moving up is not available as 16 mm is the largest in this series. For practical sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical push) to account for seal friction and smooth travel. This equates to lifting about 5.1 kg vertically with a 2:1 safety margin.
A plain double-acting cylinder like this does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For fail-safe holding, specify an external stop or rod lock. Confirm your ordering essentials: 16 mm bore, 5 mm stroke, M5x0.8 port, S magnet, R axial inlet, and any required LB, FA, or CJ mounting brackets.
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 PB16X5SR 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 and a proof pressure of 1.2 MPa.
No, a standard double-acting cylinder does not hold its load without live pressure; the piston will drift. The fixed TPU bumper only decelerates the rod near the end of travel and acts as neither a lock nor a brake. You must add an external rod lock or mechanical stop for fail-safe vertical holding.
