About the Airtac STWB Slide Table Cylinder STWB20X75S
This code orders the STW slide cylinder fixed through its body (B) with a Dia 20 bore and an extended 75 mm stroke. The longer travel gives 25 mm more reach than the 50 mm version while the theoretical force stays at 201.1 N at 0.5 MPa, and hydraulic shock absorbers still absorb both stroke ends.
Because 75 mm remains within the 100 mm threshold, stroke tolerance is the tighter +1.0 / 0 mm band. Twin rods limit rotation to 0.05 deg so the slide plate stays aligned over the longer span, while the built-in magnet with its sensor rail and three sets of M5x0.8 ports simplify position feedback and piping.

How to choose
Choose STWB20X75S when stroke, not force, is the deciding dimension: STWB20X50S halves the travel and STWB20X100S doubles it, and STWA20X75S switches to end-plate fixing. Force-wise the Dia 16 STWB16X75S drops to 122.5 N while the Dia 25 STWB25X75S raises it to 289.8 N, so this bore sits mid-range.
Applications
Extend-to-grip station
The 75 mm reach lets jaws or a suction plate enter a nest that a 50 mm slide cannot clear, then retract fully out of the robot's path.
Cross-transfer between conveyors
Body fixing suits a bracket under the transfer line, and the extra travel bridges the gap between two lanes without repositioning the whole unit.
Guided alignment slide
0.05 deg anti-rotation over 75 mm keeps a guide or aligner plate parallel to the machine datum across the full stroke.
FAQ
What are the key figures of the STWB20X75S?
Dia 20 bore, 75 mm stroke, body-fixed (B) mounting, magnet built in (S), M5x0.8 ports, theoretical force 201.1 N at 0.5 MPa, operating pressure 0.15-1.0 MPa, speed 30-500 mm/s, temperature -20 to +70 C, anti-rotation 0.05 deg, stroke tolerance +1.0 / 0 mm.
Does the 75 mm stroke change the port size or the pressure range?
No. Stroke length does not alter the ports or the pressure band: Dia 20 uses M5x0.8 ports and works at 0.15-1.0 MPa on air filtered to 40 um. Only strokes above 100 mm would relax the stroke tolerance to +1.5 / 0 mm.
