SL2

Torque limiters

The dynamic SL2 safety coupling from R+W Couplings is compact, lightweight, corrosion-resistant, low moment of inertia, easy to assemble and disassemble, and features a simple design. Due to the friction clamp connection, this precision coupling is torsionally rigid and completely free of play. Thanks to the forcibly formed bellows, the element can simultaneously compensate for lateral, axial, and angular misalignment errors. The maximum torque of the SL2 safety coupling can also be manually adjusted using an adjusting wrench. This key can be ordered separately. For specific inquiries about safety couplings or other precision couplings, please contact VARIODRIVE.
