About the Airtac STWB Slide Table Cylinder STWB25X125S
The AirTAC STWB25X125S is a Dia 25 mm bore slide cylinder from the STW series with body-fixed mounting (B in the code) and a 125 mm stroke. As a double-acting twin-rod unit it resists bending and twisting, so it tolerates larger moving and side loads than a single-rod cylinder of the same size. Hydraulic shock absorbers cushion both stroke ends, slowing impact and extending service life.
At 0.5 MPa the Dia 25 bore delivers a theoretical force of 289.8 N, and piping is via PT1/8 ports with three sets available so you can choose the piping direction. Twin rods hold rotation to within 0.03 degrees, and the S option confirms the built-in magnet riding on the sensor mounting rail for switch position feedback.

How to choose
This code sits in the middle of the Dia 25 stroke list: STWB25X100S gives 100 mm of travel and STWB25X150S gives 150 mm, so pick the 125 mm version when your slide travel falls between the two standard neighbours. If you need the same bore and stroke but fix the unit by its end plate instead of its body, order the plate-fixed STWA25X125S. Above 100 mm stroke the tolerance is +1.5 / 0 mm, worth checking when you locate stops or sensors.
Applications
Pick-and-place slides
The 289.8 N thrust of the Dia 25 bore and 0.03 degree anti-rotation keep a gripper plate square across the full 125 mm transfer stroke.
Conveyor push-off stations
Body-fixed mounting lets the cylinder hang from the machine frame while the slide pushes cartons off the line over 125 mm of travel.
Indexing fixture clamping
Hydraulic shock absorbers at each end let the slide seat a fixture against a stop at 125 mm without hammering the tooling.
FAQ
What are the key figures for the STWB25X125S?
Body-fixed (STWB) mounting, Dia 25 mm bore, 125 mm stroke, double acting twin rod, theoretical force 289.8 N at 0.5 MPa, operating pressure 0.15-1.0 MPa, ports PT1/8, anti-rotation 0.03 degrees, speed 30-500 mm/s, temperature -20 to +70 C, built-in magnet with sensor rail.
How do I add position sensing to this cylinder?
The S option means a magnet is built in and a sensor mounting rail runs along the unit, so reed or solid-state switches can be clipped on and positioned anywhere along the 125 mm stroke to signal end or mid positions.
