SLE

Torque limiters

The dynamic SLE safety coupling from R+W Couplings is compact, extremely lightweight, corrosion-resistant, low moment of inertia, easy to assemble and disassemble, and features a simple design. Due to the friction clamp connection, it is completely free of play. The SLE safety coupling can be combined with two different types of R+W elastomer spiders, types A and B. Both types of R+W elastomer spiders dampen vibrations and provide electrical insulation. The maximum torque of the SLE 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.
