Couplings |  |
Couplings - Jaw Type - With Polyurethane Spider (Relevance 5/10)
Miniature aluminium curved jaw flexible couplings. 2 to 160 Nm.
Discs (either red as standard with blue or white optional) are available to purchase separately. Flexible couplings transmit torque and rotational angle while absorbing misalignment. When the misalignment exceeds allowable values, vibration may result or the life of the coupling may become shortened. Zero backlash in low torque application, made capable by having the hubs pressed in a spacer. Can be used as a flexible coupling in a high torque application.
