Aventics TWC-series dual-piston cylinders are double-acting pneumatic actuators with two parallel pistons on a shared piston rod. The tandem piston arrangement doubles the effective pressure area, producing significantly higher thrust at the same operating pressure compared with a single-piston cylinder of the same bore. The TWC series is available in two variants: TWC-HL with plain bronze bushing guidance and TWC-RL with roller-bearing guidance. Bore sizes range from 16 mm to 25 mm, strokes from 30 mm to 80 mm.
| Criterion | TWC-HL | TWC-RL |
|---|---|---|
| Guidance principle | Plain bronze bushing | Roller bearing |
| Lateral load capacity | Standard | Increased |
| Bore diameters | 16, 20, 25 mm | 16, 20, 25 mm |
| Available strokes | 30-80 mm | 30-80 mm |
| Typical use | Pushing, clamping without lateral load | Pushing, clamping with lateral load |
Typical applications: Clamping and holding fixtures in mechanical engineering where high clamping force is required in a compact space; gripper and transfer systems in assembly automation; press and joining units where two mechanically synchronised pistons deliver even force onto a workpiece; labelling and packaging machinery; feed units in food and beverage processing.
