SLN

Torque limiters

The dynamic SLN safety coupling from R+W Couplings is equipped with an integral bearing for a toothed belt pulley or gear. The safety coupling is 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. The integral bearing makes it easy to mount a toothed belt pulley or gear. The maximum torque of the SLN 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.
