Airtac PB Pen-type Cylinder PB16X50SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X50SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 50mm 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 PB16X50SCB
The AirTAC PB16X50SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency tasks. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a 16 mm bore and a 50 mm stroke. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments without adding excessive bulk to your end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position detection and a CB double clevis back cover for pivoting loads. Fluid is filtered air, operating pressure ranges from 0.15 to 0.7 MPa, and the M5x0.8 port ensures reliable pneumatic supply. It reaches speeds of 50-800 mm/s, decelerating via a fixed TPU bumper at each end rather than an adjustable air cushion.

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 PB16X50SCB Is Used
Pivot-Actuated Clamping
Ideal for swinging a small clamping arm onto machined aluminum blocks, utilizing the CB double clevis to accommodate the pivot arc while delivering 100.5 N of clamping force.
Carton Flap Folding
Drives a lightweight folding blade on a packaging line to tuck corrugated carton flaps, where the slim 16 mm body fits neatly between conveyor guides.
Vertical Parts Lift
Elevates small electronic components out of a vibratory bowl feeder, safely lifting parts weighing up to roughly 5.1 kg with a 2:1 safety margin at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB16X50SCB the Right Cylinder?
Choosing this 16 mm bore gives you the highest thrust in the PB pen-size family, pushing 100.5 N at 0.5 MPa. If you need slightly less force, stepping down to the 12 mm bore yields 56.5 N of push. Because this is the largest standard diameter available, there is no larger option in this series. For sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa figure) to account for seal friction, or expect to vertically lift about 5.1 kg with a sane 2:1 safety margin.
When ordering, verify your requirements for the 16 mm bore, 50 mm stroke, M5x0.8 air port, S magnet, and CB double clevis mount. Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For fail-safe positioning, an external stop or rod lock is required.
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 PB16X50SCB FAQ
This double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, reaching maximums of 140.7 N push and 126.9 N pull at the 0.7 MPa operating pressure limit. It operates at speeds of 50-800 mm/s, uses an M5x0.8 port, and features a 5 mm rod with an M10x1.0 rod-end thread.
The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position sensing. Cushioning is handled by a fixed TPU bumper at each end, which is not field-adjustable; for high-speed or heavy mass loads, you should meter-out the exhaust or add an external shock absorber.
