Belonging to the ultra-compact 6800 series, the 6807-ZZ is a single-row, thin-section deep groove ball bearing equipped with dual metal shields. With a 35 mm bore, a 47 mm outer diameter, and a slim 7 mm profile, this bearing delivers exceptional space-saving advantages. Unlike open-type bearings, the 6807-ZZ features non-contact steel shields on both sides, making it a maintenance-free, factory-greased solution. It is specifically engineered to retain lubricants internally while effectively blocking dust, metallic shavings, and other external contaminants. This shielded configuration provides a perfect balance—offering robust environmental protection without introducing the heavy rotational drag associated with rubber seals, ensuring high-speed capability with minimal friction.
