MOM is an Oldham type flexible coupling with charactaristics such as large permissible misalignment, high-torque, long-term maintenance free.
The spacer is made of FCD400 and it's suitable for low-speed and high-torque specification.
High performance grease is applied in the gap between hubs and the spacer in order to prevent sticking. Slippage of hubs and a spacer allows large eccentricity and angular misalignment to be accepted. A projection placed in the spacer (resin pin) allows angular misalignment to be effortlessly accepted.
The grease accumulated in a grease hole will gradually seep out during operation, thereby maintaining the lubrication property over a long period.
