Torque limiters

The SKP safety coupling from R+W Couplings features a compact and simple design. Additionally, this coupling features fast and accurate disengagement detection and disengagement. Due to the friction clamp connection, this precision coupling is completely free of play. The integral bearing makes it easy to mount a toothed belt pulley or gear. The maximum torque of the SKP safety coupling can also be manually adjusted using an adjusting wrench. This key can be ordered separately. Thanks to the forcibly formed bellows shape, the element can simultaneously compensate for lateral, axial, and angular misalignment errors. This key can be ordered separately. For specific inquiries about safety couplings or other precision couplings, please contact VARIODRIVE.
