Horton Nexen SSE-45020 MM 818829 spring-loaded friction brake, with a 7/8" bore. As a friction brake, it slows or holds a rotating shaft by bringing a friction surface into contact with the shaft to create braking torque. The SSE-45020 MM 818829 designations identify the specific Horton Nexen model and part number, providing the exact bore size and configuration required for compatibility with shafts that accept a 7/8" bore. This information helps verify fit and function in mechanical systems that require spring-applied braking on rotating components.
