Product Description

The Koyo 5307 2RS is a double row angular contact ball bearing designed to accommodate combined loads, supporting both radial and axial forces in both directions. Its double-row construction provides high rigidity and load-carrying capacity in a compact form factor.

The 2RS rubber seals on both sides protect the internal raceways and balls from contamination while keeping the factory-applied grease inside, making this bearing suitable for applications where maintenance access is limited or where additional sealing is required.

With a standard steel cage, normal internal clearance (CN), and a maximum operating temperature of up to 120 °C, this bearing is well-suited for a wide range of industrial and power transmission applications.
