Airtac PB Pen-type Cylinder PB16X135SR
The AirTAC Airtac PB Pen-type Cylinder PB16X135SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 135mm 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 PB16X135SR
The AirTAC PB16X135SR is a JIS pen-size double-acting single-rod mini cylinder, engineered for high-frequency small-part motion in compact spaces. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, peaking at 140.7 N push under the 0.7 MPa maximum operating pressure. The SUS304 stainless barrel and piston rod resist moisture and mildly corrosive environments, ensuring durability without the bulk of larger profile bodies.
This specific configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet (-S) for position sensing. Air flows through an M5x0.8 port, while the Ø5 mm rod features an M10x1.0 end thread for secure load coupling. Travel is capped by a fixed TPU bumper at each end that decelerates the last few millimeters of the 135 mm stroke, operating at speeds between 50 and 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 PB16X135SR Is Used
PCB Depaneling Router
Advances a cutting tool guide along a 135 mm path, utilizing the 100.5 N push force to maintain steady feed rates while the stainless body resists fiberglass dust.
Carton Flap Folder
Tucks small corrugated flaps on a packaging line, where the compact pen-size profile fits neatly between conveyor belts and the R axial inlet keeps plumbing flat.
Lab Sample Dispenser
Actuates a pipette head over a 135 mm stroke to deposit reagents, relying on the built-in S magnet to trigger an electronic switch for precise volume metering.
Is the Airtac PB Pen-type Cylinder PB16X135SR the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N (roughly 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. For vertical lifts, this translates to lifting about 5.1 kg safely with a 2:1 margin. If you need to step down force, the adjacent Ø12 bore provides 56.5 N push at 0.5 MPa; stepping up is not available as Ø16 is the largest in this series. Because the thin Ø5 mm rod is designed for coaxial thrust over its 135 mm stroke, add an external linear bearing if the application involves off-axis loads.
A plain PB cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, and the bumper only decelerates near the stroke end, acting as neither a lock nor a brake. For fail-safe holding, specify an external rod lock. To finalize your order, confirm the 16 mm bore, 135 mm stroke, M5x0.8 porting, S magnet for reed or electronic switches, 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 PB16X135SR FAQ
This 16 mm bore 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 pressure limit. It operates at speeds from 50-800 mm/s within a 0.15-0.7 MPa pressure range.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel, which is not field-adjustable; for high mass at mid-speed, add an external shock absorber. The included -S magnet allows AirTAC reed or electronic switches to read piston position.
