Airtac PB Pen-type Cylinder PB16X90SR
The AirTAC Airtac PB Pen-type Cylinder PB16X90SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 90mm 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 PB16X90SR
The AirTAC PB16X90SR is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a 16 mm bore and a 90 mm stroke. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping end-of-arm tooling lightweight. This configuration includes an R axial air inlet for in-line plumbing and an integrated S magnet for position sensing.
Air enters via the M5x0.8 port, driving the Ø5 mm rod with its M10x1.0 end thread at speeds from 50 to 800 mm/s. End-of-stroke deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs impact over the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber. Plan for a safe working load of roughly 60 N to account for seal friction and smooth travel.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

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 PB16X90SR Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics assembly line, where the stainless body resists flux fumes and the 100.5 N thrust securely clamps boards during routing.
Blister Pack Sealing
Drives a small heat press platen for medical blister packaging, using the S magnet to confirm seal position and the R axial inlet to keep pneumatic plumbing flat against the machine frame.
Sorter Diverter Gate
Pushes lightweight parcels on a logistics conveyor, lifting parts up to 5.1 kg vertically with a 2:1 safety margin while fitting neatly within tight transfer chutes.
Is the Airtac PB Pen-type Cylinder PB16X90SR the Right Cylinder?
This 16 mm bore provides the highest standard thrust in the PB family, stepping up from the 12 mm option which yields 56.5 N of push at 0.5 MPa. When sizing your system, remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper decelerates the stroke but does not function as a locking brake, so mount an external rod lock if you need fail-safe position holding. To order, confirm the 16 mm bore, 90 mm stroke, M5x0.8 porting, S magnet for reed or electronic switches, and the R axial inlet back cover.
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 PB16X90SR FAQ
At 0.5 MPa this cylinder provides 100.5 N of push and 90.7 N of pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15 and 0.7 MPa at speeds of 50-800 mm/s, with a proof pressure of 1.2 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends and do not act as a brake. You must add an external rod lock or mechanical stop to safely hold a suspended load.
