6314-ZZ Deep Groove Ball Bearing 70×150×35mm Double Metal Shield Heavy Duty Bearing GQZ

• 6314-ZZ is a heavy-duty single row deep groove ball bearing with standard dimensions 70×150×35mm, fitted with double-sided ZZ stamped steel dust shields. The solid metal shield structure blocks dust, sand and solid particles effectively, protecting internal grease and rolling elements from contamination in dry, dusty industrial environments. Pre-filled with high-temperature lubricating grease at factory for long-term maintenance-free operation. Its enlarged ball structure delivers remarkable radial load capacity and can withstand light bidirectional axial loads simultaneously, supporting stable medium-speed continuous operation. Strictly controlled dimensional tolerance and polished raceways guarantee quiet running and stable performance, widely used for heavy-load transmission machinery in mining, agriculture and general industrial fields.
