Fafnir F5DD Single Row Ball Bearing 11/16 OD 5/16 ID

The Fafnir F5DD is a single-row ball bearing with a 11/16 in outer diameter and a 5/16 in inner diameter, designed for compact installations where space is tight. As part of Fafnir's F5DD family, it uses the standard radial-ball bearing construction, with steel balls rolling between inner and outer races to enable smooth rotary motion and support radial loads in mechanical assemblies. The F5DD designation identifies this specific bearing within Fafnir's lineup, providing a reliable, replaceable component for applications requiring a small bore paired with a larger outer diameter. With OD 11/16 in and ID 5/16 in, the bearing fits shafts and housings sized to those dimensions, subject to mounting clearances and method. For proper selection and replacement, verify your shaft diameter, bore, and coupling tolerances match these dimensions, and consult official Fafnir specifications to confirm any applicable tolerance grades and lubrication recommendations. This description preserves the exact dimensions to ensure precise identification when sourcing or ordering the F5DD bearing.
