About the Airtac PB Pen-type Cylinder PB10X55SU
The AirTAC PB10X55SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It utilizes a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive work areas while keeping end-of-arm tooling payload low. Delivering 39.3 N of push force at 0.5 MPa, this 10 mm bore unit features an M5x0.8 port and a 4 mm rod with an M8x1.0 rod-end thread.
This specific configuration includes a built-in piston magnet (-S) for position sensing with AirTAC reed or electronic switches, and a U-type back cover providing a 90-degree side air inlet for flat plumbing in tight spaces. It relies on a fixed TPU bumper at each end to decelerate the stroke. Because the bumper only absorbs energy over the final few millimeters, high-speed cycling with real tooling mass requires metering out the exhaust or adding an external shock absorber.

| 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 |

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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PB10X55SU Is Used
PCB Pick-and-Place
Drives lightweight suction grippers in electronics assembly lines, using its 55 mm stroke to lift delicate circuit boards without overwhelming the 24 N safe working load.
Blister Pack Sorting
Pushes small pharmaceutical blister packs into sorting chutes, where the U-type 90-degree side inlet keeps pneumatic plumbing flat against the machine frame to save space.
Lab Reagent Dispensing
Actuates tiny dosing valves in wet laboratory environments, benefiting from the SUS304 stainless construction to resist mild chemical corrosion during reagent handling.
Is the Airtac PB Pen-type Cylinder PB10X55SU the Right Cylinder?
When sizing this 10 mm bore actuator, consider stepping down to the Ø6 class for lighter duties, which provides 14.2 N of push at 0.5 MPa, or moving up to the Ø12 bore for heavier loads, which yields 56.5 N at the same pressure. For the PB10X55SU, a safe working load is approximately 24 N (about 60 percent of the 39.3 N theoretical force at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift scenarios, plan for lifting about 2 kg to maintain a sane 2:1 safety margin.
The thin 4 mm rod is designed strictly for coaxial thrust; over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-load damage. A plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end. For a fail-safe hold, an external stop or rod lock is required. Confirm your ordering essentials: 10 mm bore, 55 mm stroke, M5x0.8 port, S magnet, U 90-degree side inlet, and appropriate mounts.
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 PB10X55SU FAQ
This double-acting single-rod cylinder delivers 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 55 N push and 46.2 N pull. It operates between 0.15 and 0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not field-adjustable or capable of holding a load. The built-in magnet (-S) allows you to track position using AirTAC reed or electronic switches along the slim SUS304 barrel.
