6302-2Z Bearing Product Overview & Core Advantages
The 6302-2Z is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its shielded construction (2Z) provides effective contaminant protection while the P6 tolerance class ensures high running accuracy. This bearing excels at handling radial loads with a dynamic load rating of 2675 lbf, making it suitable for applications requiring precise rotation and long service life. The pre-lubricated design with grease offers immediate operation readiness and maintenance-free performance across a wide temperature range (-30° to 120°C).
