U604ZZ U Groove Pulley Ball Bearing 4x13x4mm 604ZZ

The U604ZZ is a type of miniature bearing that is double-row, self-lubricating, shielded, and often used in linear motion systems, 3D printers, belt systems, and small conveyor machines. Its "U"-shaped groove design makes it compatible with belt or rail systems, allowing it to handle both radial and axial loads.

The "ZZ" designation means the bearing is shielded on both sides with metal covers, which protect it from dust and contaminants.
