Spiders elastic black | Size 28/38 | 94° Shore A | made of PU
The Spiders elastic form the elastic heart of the jaw coupling and significantly determine its transmission behavior. Manufactured in the striking black color, this spider has a defined hardness of 94° Shore A. It serves as a damping connecting element between the coupling halves and ensures the compensation of shaft misalignment as well as the reduction of torque peaks. This spider in size 28/38 with 8 teeth convinces with its specific damping behavior (medium) and is designed for a maximum speed of 8500 rpm. It guarantees reliable function in a temperature range of -40°/+140°. By selecting the appropriate Shore hardness, the entire coupling system can be optimally adapted to the requirements regarding vibration isolation and torsional stiffness.
