A practical choice for anyone replacing a worn 6702RS bearing in a compatible bicycle hub, freehub or other compact rotating assembly.
The 6702RS is a steel deep-groove cartridge bearing for compact rotating assemblies. Its metric dimensions are 15 mm bore × 21 mm outside diameter × 4 mm wide, making accurate measurement and matching the marking on your existing bearing essential before ordering.
The RS rubber seal helps shield the internal raceway from moisture, dust and other contaminants. Deep-groove bearings are designed primarily for radial loads and are commonly used in compact mechanical systems, including some lightweight bicycle hub and freehub applications.
Choose this bearing when you need a straightforward 6702RS replacement with an ABEC-3 precision rating. It is a component rather than a complete service kit, so confirm the number of bearings, installation method and exact fitment for your hub or other assembly before purchase.
