The Yaesu GS-065 Rotator Mast Bearing is an essential component for amateur radio enthusiasts seeking to enhance the stability and longevity of their antenna systems. Designed to support masts with an outer diameter of up to 65 mm (approximately 2.5 inches), this medium-weight thrust bearing ensures smooth and reliable rotation of directional antennas, even under substantial lateral wind forces.

Key Features and Specifications:

• Robust Housing: Constructed from highly corrosion-resistant die-cast aluminum, the GS-065's housing is finished with baked enamel, providing exceptional durability and protection against harsh environmental conditions.
  

• Secure Mast Attachment: Equipped with four lock nuts, this bearing guarantees a firm and reliable connection to the mast, minimizing the risk of slippage or misalignment during operation.
  

• Hardened Mounting Bolts: The inclusion of hardened mounting bolts enhances the overall structural integrity, ensuring the bearing remains securely fastened to the supporting structure.
  

• Advanced Bearing Mechanism: Featuring a dependable two-level bearing system lubricated with metallic molybdenum grease, the GS-065 offers a virtually unlimited operational lifespan, maintaining consistent performance over time.
  

• Innovative Retaining Plate: The newly designed retaining plate mechanism transitions the mast contact from point to surface contact. This design change significantly reduces the potential for mast breakage or corrosion, enhancing the system's overall resilience.
  

• Versatile Compatibility: Capable of accommodating masts ranging from 1.5 inches to 2.5 inches in diameter, the GS-065 is suitable for a wide array of antenna setups, offering flexibility to meet various installation requirements.
  
  

Incorporating the Yaesu GS-065 Rotator Mast Bearing into your antenna system not only stabilizes and secures your mast but also ensures smooth and steady rotation, even under challenging conditions. Its robust construction and advanced features make it an indispensable accessory for achieving optimal performance and longevity of your directional antennas.
