SPERRY MARINE PULLEY 84 GROOVE PULSE DISC ASSEMBLY: The Sperry Marine Pulley 84 Groove Pulse Disc Assembly is an essential part of radar systems, primarily responsible for ensuring smooth mechanical motion in the radar’s scanning system. It helps transmit power from the motor to the radar’s antenna, enabling it to rotate efficiently and scan the surroundings. The 84 grooves on the disc ensure that the radar’s movements are precise and uniform, improving the overall accuracy and performance of the system. This component is critical for the longevity and reliability of radar operations in maritime settings.
