AirTAC PB Series Pen-Size Cylinders
The AirTAC PB series is a JIS pen-size mini air cylinder built for high-frequency small-part motion, spanning 4-16mm bores with a stainless steel rod and barrel for wet or corrosive areas.
inventory_2619 models availableSeries Overview
The AirTAC PB series is a standard single-rod, double-acting pen-size (mini) air cylinder built to JIS dimensions. It features a slim round barrel with screwed-in front and back covers. The piston rod and barrel are stainless steel (SUS304 on bores 6-16; bronze barrel on bore 4), making it suitable for generally corrosive or wet environments.
The range spans five bores from 4 to 16mm, with standard strokes reaching up to 300mm on the 16mm bore. Maximum operating pressure is 0.7 MPa across the entire PB family. Force output spans from about 6N to 100N at 0.5 MPa, and 9N to 141N at the 0.7 MPa maximum. Ports are M3x0.5 on the 4mm bore and M5x0.8 on the 6-16mm bores.
Shared design features include double-acting operation and fixed TPU elastic bumpers on both ends for bores 6-16 (bore 4 has no cushion). This is a fixed bumper, not an adjustable air cushion, and it will not hold a load if pressure is lost. An -S magnet option is available for position switches. Back cover options include CB, U, and R, with optional LB, FA, and CJ brackets. It is a JIS pen-size mini cylinder, not an ISO 15552 or ISO 6432 profile cylinder.

Typical Applications
Small-Part Pick-and-Place
The slim 4-16mm profile and fast response suit high-frequency small-part motion in automated assembly, where the stainless barrel handles occasional coolant or washdown.
Lab Diagnostic Equipment
The non-corrosive SUS304 rod and compact pen-size design fit tightly into lab analyzers and diagnostic machines driving small grippers and stops.
Light Packaging Diverters
Fixed TPU bumpers on bores 6-16 absorb end-of-stroke impact for light sorting and diverting gates in packaging lines without needing external shock absorbers.
Paper Feed Mechanisms
The 4mm and 6mm bores provide the low 9N to 20N push force needed for precise paper feeding and registration in printing and copying devices.
How to Choose the Right Model
Choose the bore based on your force requirement at 0.7 MPa: the 4mm bore provides up to 9N, while the 16mm bore provides up to 141N. Select the stroke length up to the series maximum of 300mm. Confirm the port size (M3x0.5 for bore 4, M5x0.8 for bores 6-16) and choose the required back cover (CB, U, or R) and bracket (LB, FA, or CJ) for your mounting interface. Add the -S magnet option if you need position sensing.
If your application involves heavy side loads or requires an ISO 15552 or ISO 6432 profile interface, step out of the PB series. For a larger stainless round mini cylinder, consider the AirTAC MI series. For aluminum-barrel minis, see the AirTAC MBL series. Related variants include the PSB/PTB (single acting), PBD (double rod), and PBJ (adjustable stroke). Always confirm from the datasheet for exact temperature limits and air quality requirements (40 um).
Practical 5-point match to confirm before ordering: 1) Bore size (4-16mm), 2) Stroke length, 3) Port/thread size, 4) Mounting bracket and cover style, 5) Magnet (-S) requirement.

Frequently Asked Questions
The PB series spans 5 bores from 4 to 16mm, with standard strokes up to 300mm on the 16mm bore. Maximum operating pressure is 0.7 MPa. Push force spans from about 6N (bore 4) to 100N (bore 16) at 0.5 MPa, and 9N to 141N at the 0.7 MPa maximum.
The standard PB is double-acting single-rod. Bore 4 has no cushion, while bores 6-16 use fixed TPU elastic bumpers (not adjustable air cushions). You can choose CB, U, or R back covers, and LB, FA, or CJ brackets. An -S magnet option is available for switches. Related families include PSB/PTB (single acting), PBD (double rod), and PBJ (adjustable stroke).
No. The PB series is a JIS pen-size mini cylinder. It features a slim round barrel with screwed-in covers, not an ISO 15552 tie-rod profile or an ISO 6432 standard interface. It is designed for compact, high-frequency small-part motion rather than ISO drop-in replacement.
No. The PB series is a double-acting air cylinder and will not hold position if pressure is lost. The TPU bumpers on bores 6-16 only decelerate the piston near stroke end; they do not act as a lock or brake. If load holding is required, a mechanical lock, rod brake, or pilot check valve must be used.
