Rotary encoder : ERB Series

Flexible coupling – ERB Series

Autonics flexible coupling ERB Series features strong resistance against distortion as it is made of super-high strength aluminum alloy (AL 7075-T6), and it realizes high corrosion resistance through applying alumite surface treatment. In addition, ERB series supports two different connection types - Clamp type and Set screw type - so that it can deliver more accurate revolution driving power and protect revolving objects from backlash.

Main features
* High torsional stiffness by high strength aluminum alloy AL 7075-T6
* High corrosion resistance by alumite treated surface
* Two connection types(Clamp type, Set screw type)
* Zero(0) Backlash
