SELF-SANITISATION AGAINST BACTERIA AND FUNGI
Steel

Material
Hardened steel.
Standard executions
Assembly by means of two supplied zinc-plated steel grub screws with hexagon socket.
- GN 297-R: gear with teeth for clockwise rotation.
- GN 297-L: gear with toothing for anti-clockwise rotation.
- GN 297-W: set of two gears, one for clockwise rotation and the other for anti-clockwise rotation. Ratio 1:1.
- GN 297-T: set of three gears, one for clockwise rotation and the other two for anti-clockwise rotation. Ratio 1:1.
Features and applications
GN 297 angular gears are normally used with the linear actuators, connecting units GN 391 and/or the connectors GN 298.
The helical toothing ensures better coupling between the conical gears, reducing the clearance and consequently the noise level.
Two conical gears are needed to make an angular rotation (GN 297-W).
Three conical gears are needed to make a T rotation (GN 297-T).
