Product Description

The Koyo 6409-3ZZ is a single row deep groove ball bearing designed for high radial load capacity and moderate axial loads in both directions. Deep groove ball bearings are versatile, low-friction bearings suitable for high-speed applications.

This model features double metal shields (ZZ), which help protect the internal components from contamination and keep the factory-applied grease inside the bearing. This makes it a good choice for applications where low maintenance and reliable sealing are important.

With a steel cage, normal internal clearance (CN), and operating capability up to 120 °C, the 6409-3ZZ is suitable for a wide range of industrial, electric motor, and power transmission applications.
