6302ZZ Single Row Deep Groove Ball Bearing Double ZZ Metal Dust Shield 15x42x13mm Motor Conveyor Agricultural Equipment

The 6302ZZ single row deep groove ball bearing is equipped with double-sided ZZ non-contact metal dust shields, standard size 15×42×13mm. It features thickened steel ball structure for larger load capacity, capable of bearing radial load and slight bidirectional axial load. Double metal shields block dust, wood chips and particulate impurities, lock internal long-life grease, widely used in small electric motors, conveyors, agricultural machinery, garden equipment and general industrial transmission assemblies.

• Non-contact ZZ metal shields produce low friction, effective dust blocking without limiting rotation speed
• Precision superfinished raceway ensures smooth low-noise operation under continuous load
• High-hardness quenched bearing steel improves wear resistance for dusty harsh working conditions
• Multiple optional variants: open 6302, splash-proof 6302-2RS, C3 clearance version
• Stainless steel anti-rust model can be customized for food and damp workshop environments
