Rohn BAS25G Tower Bearing Plates

Top Bearing Accessory Shelf for Rohn 25G Towers
The Rohn BAS25G Accessory Shelf with Top Bearing Plate is a purpose-built platform for securely mounting rotors, thrust bearings, and masts at the top of your Rohn 25G tower. This complete assembly combines a sturdy top and bottom plate with integrated tubular support legs, creating a dependable structure for rotor installations and antenna mast stabilization. It's a go-to solution for tower builders looking to finish their setup with a robust, rotor-ready interface.

Engineered for Rohn 25G Tower Compatibility
Specifically designed for Rohn 25G tower sections, the BAS25G accessory shelf installs directly onto the topmost straight section of the tower. With standardized mounting points and correct plate spacing, it ensures a seamless fit without requiring custom hardware or modification. It’s an ideal match for ham radio operators, broadcast engineers, and tower crews needing a professional-grade rotor shelf setup.

Pre-Drilled for Rotor and Thrust Bearing Mounting
The top plate is pre-drilled to accept the DXE-TB-300 or Rohn TB-3 thrust bearings, providing an immediate mounting surface for heavy-duty mast support. The accessory shelf below is also pre-drilled to accommodate a wide range of commonly used rotor models. This precision layout saves time during installation and guarantees secure, vibration-free operation.

Built for Structural Integrity and Mast Clearance
With a plate-to-plate distance of 16 inches, the BAS25G provides ample clearance for rotor operation and mast movement. The tubular support legs distribute weight and stress evenly across the mounting surface, ensuring long-term stability even under load from high-gain directional antennas or stacked mast assemblies.

Durable Galvanized Construction for Harsh Environments
All metal components of the BAS25G are hot-dip galvanized, offering long-lasting resistance to rust and corrosion. This rugged finish ensures that the shelf assembly remains dependable even after years of exposure to wind, rain, and sun—making it suitable for permanent outdoor installations.

Streamlined Rotor Installation and Maintenance
The BAS25G makes rotor servicing and replacement easier thanks to its clear separation between thrust bearing and rotor shelf. With smart spacing and a solid support frame, it simplifies the process of aligning the rotor with the mast while reducing wear on components during use.
