Raymarine Wind Transmitter Bearing Service Kit

The Raymarine Wind Transmitter Bearing Service Kit (TA122) is an essential maintenance component for mariners who depend on accurate wind data for navigation and sail trim. Over months of exposure to salt spray, UV radiation, and constant rotation, the bearings in a wind transmitter degrade—leading to sluggish response times and unreliable readings at the helm. This service kit restores your wind instrument to factory performance, whether you're racing competitively, cruising blue water, or navigating coastal passages where wind awareness directly impacts safety and efficiency.

Raymarine's TA122 kit addresses bearing wear and friction that accumulates in the transmitter head, which houses the anemometer vane and wind direction sensor. The service kit contains replacement bearings engineered to precise tolerances, ensuring smooth 360-degree rotation and responsive signal transmission to your Raymarine instrument display or integrated navigation system. These bearings are treated to resist corrosion from the marine environment, maintaining their performance across saltwater and freshwater applications. Proper bearing condition is critical—worn bearings introduce lag in wind angle and speed reporting, which directly affects autopilot performance and sail-trim accuracy.

This kit is compatible with Raymarine TA122 wind transmitters found on cruising sailboats, performance racers, and trawlers equipped with Raymarine's i70s, i70, or ST60+ wind instruments. Installation is straightforward for anyone with basic mechanical aptitude—no specialized tools required—though consulting your system manual is recommended. Regular bearing maintenance extends transmitter lifespan by 5–10 years and prevents the costly replacement of the entire sensor head. Order this kit as part of your spring haul-out routine or whenever you notice sluggish wind readings or intermittent data dropout.
