About the AirTAC PSB12
The AirTAC PSB12 is a single-acting, spring-return pen cylinder (push type) with a 12 mm bore and a 5 mm piston rod. Compressed air extends the rod and a built-in spring retracts it when the air is released, so the rod rests retracted; only one port takes air. Catalog output with the spring force already deducted is 42.9 N push at 0.5 MPa and 65.5 N at 0.7 MPa. The spring stroke has no air behind it, so it must not carry a load.
All PSB12 versions share M5×0.8 air ports, an M10×1.0 rod thread and rubber bumpers at both ends. The cylinder runs on filtered air between 0.2 and 0.7 MPa (proof 1.2 MPa), from -20 to +70 °C, at 50 to 800 mm/s. This page lists 59 stock order codes with strokes from 5 to 60 mm; the catalog maximum stroke is 60 mm.

Where the PSB12 Is Used
Small pushers and stoppers
About 42.9 N at 0.5 MPa suits light pushers, stoppers, gates and ejectors.
Packaging and assembly
Compact strokes for feeders, diverters and assembly stations.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right PSB12 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the back cover and mounting. The back cover sets how the rear of the cylinder is fixed or where its air enters (CB double-clevis cover, R axial-port cover, U radial-port cover). Mounting brackets on this page: LB foot bracket. R and U covers set the rear air inlet (axial or radial); the CB double-clevis cover lets the cylinder pivot. Ø6 is built with the R axial-port cover only.
Finally pick the version: S adds a magnet for position sensors.
AirTAC PSB12 FAQ
Air extends the rod with about 42.9 N at 0.5 MPa (catalog value, spring force deducted); the internal spring retracts it when the port is vented. The force does not depend on the stroke code.
No. The return stroke is driven only by the internal spring, and AirTAC specifies that single-acting cylinders must not be loaded on it. Use a double-acting model if both directions must do work.
M5×0.8 ports.
Back covers: CB double-clevis cover, R axial-port cover, U radial-port cover. Brackets: LB foot bracket. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.2 to 0.7 MPa operating pressure (proof 1.2 MPa) and -20 to +70 °C on filtered air.
No. You can order a single PSB12. Orders are processed and handed to the carrier within 3-5 business days.
