Airtac PB Pen-type Cylinder PB16X150SCBLB
The AirTAC Airtac PB Pen-type Cylinder PB16X150SCBLB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 150mm 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 PB16X150SCBLB
The AirTAC PB16X150SCBLB is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 150mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, making it the highest force class in this compact family. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while saving valuable space on light end-of-arm tooling.
This specific configuration includes a built-in piston magnet (-S) for position sensing, a CB double clevis back cover for pivoting loads, and an LB mounting bracket. Air enters via an M5x0.8 port, driving the 5mm rod at speeds of 50-800 mm/s. Deceleration is handled by a fixed TPU bumper at each end, which absorbs impact during high-frequency cycling.

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 PB16X150SCBLB Is Used
Pivoting Clamp Arm
Ideal for driving a small pivoting clamp arm on a CNC fixture, utilizing the CB double clevis to accommodate the swing arc while providing 100.5 N of clamping force at 0.5 MPa.
Package Diverter Gate
Actuates a lightweight diverter gate on a packaging conveyor, where the LB bracket secures the body and the 150mm stroke pushes cartons smoothly onto a secondary belt.
Textile Yarn Guide
Shifts a yarn guide rail across a textile loom, benefiting from the SUS304 stainless construction to resist humid manufacturing environments and high-frequency cycling.
Is the Airtac PB Pen-type Cylinder PB16X150SCBLB the Right Cylinder?
Selecting this 16mm bore provides the maximum thrust available in the PB series. If you need slightly less force, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa; there is no larger standard bore above 16mm in this family. A practical safe working load for this model is about 60 N (roughly 60% of the 0.5 MPa theoretical push) to account for seal friction and smooth travel. For vertical lifts, plan for a maximum part weight of about 5.1 kg to maintain a sane 2:1 safety margin.
Because the 150mm stroke is well within the 300mm maximum standard stroke, this is a regular catalog item. Remember that 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; apply an external rod lock for fail-safe holding. Confirm your ordering essentials: 16mm bore, 150mm stroke, M5x0.8 port, S magnet, CB double clevis, and LB mount.
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 PB16X150SCBLB FAQ
This double-acting cylinder generates a push force of 100.5 N and a pull force of 90.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push force is 140.7 N and the pull force is 126.9 N. It operates on filtered air at 0.15-0.7 MPa, runs at speeds between 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a standard PB cylinder will drift if air is lost or the valve is centered; an external stop or rod lock is required for fail-safe holding. For cushioning, it uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters. It is not field-adjustable, so at high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber.
