Need reliable ball bearings for a repair or DIY project? This pack of 10 6904ZZ deep groove radial bearings from uxcell is a handy set to have around. Each bearing measures 20mm inner diameter, 37mm outer diameter, and 9mm width – a common size used in lots of applications. They’re built with metal shields on both sides (that’s what the ‘ZZ’ means), which protect the inside from dust, dirt, and moisture, helping them last longer. Made from durable metal with a silver finish, they’re smooth-running and ready for light to moderate loads. Great for replacing worn bearings in electric motors, small machinery, conveyor rollers, wheel hubs, skateboards, RC cars, agricultural equipment, and various hobby projects. Each pack contains 10 bearings, so you’ve got spares. Always check your specs to ensure these are the right size for your needs. Affordable and practical for home workshops, makers, or maintenance tasks.
