23030 is an oldham-type coupling with a radial clamping hub, manufactured by Norelem. The unit is made out of spacer polyacetal, while the hub is made out of aluminum. It has a short assembly time, due to the radial clamping hub.
The coupling can be installed in complete assembled condition. The series is provided with an optional connection of the shaft ends to the hub hole. This instrument is characterized with its robust, backlash-free, and short design.
The D1 and D2 hub holes are designed separately with a tolerance zone.
