About the AirTAC TWQ25
The AirTAC TWQ25 is a fixed-height stopper cylinder with a Ø25 mm bore and 10-20 mm stroke, mounted by through holes or the tapped holes at both ends, used to stop pallets, boxes and workpieces on conveyors. It is double acting: air raises and lowers the stopper. The thicker piston rod resists impact better.
The rod end comes as a round rod, flat rod or roller. It follows JIS standards and needs no lubrication; the body has sensor grooves on two sides.

Where the TWQ25 Is Used
Conveyor stops
Stops pallets and cartons at a work station or buffer.
Pallet indexing
Holds loads in a queue and releases them one by one.
Assembly lines
Positions workpiece carriers for an operation.
Choosing the Right TWQ25 Configuration
Choose the stroke: 10, 15, 20 mm on Ø25, tolerance +1.0/0 mm. Size the bore with the impact load and speed charts in the catalog.
Then the stopper: C round rod; B flat rod; R roller.
S adds a magnet for position sensors.
AirTAC TWQ25 FAQ
On this bore the round rod, flat rod and roller share one impact load chart in the catalog; check your load and conveyor speed against it. The lever roller with oil shock absorber comes on Ø32 and up.
TWQ is double acting; TTQ is single acting, pull-in type: the spring raises the stopper when air is cut.
