Servo disc couplings

The SCL2 disc coupling from R+W Couplings is available in a single or double disc version. This precision coupling features a highly compact design with high torsional stiffness and can be applied in environments where high temperatures and/or corrosion may occur. Due to the use of a friction clamp hub connection, this disc coupling has a high clamping capacity, resulting in a completely play-free coupling. Additionally, the element can simultaneously accommodate lateral, axial, and angular misalignments. For specific inquiries about disc couplings or other precision couplings, please contact VARIODRIVE.
