3002Z Double Row Angular Contact Ball Bearing GCr15 Bearing Steel 15*32*13mm For Spindle Precision Equipment

3002Z is a double-row angular contact ball bearing specialized for spindle applications, integrating high rigidity and stable load-bearing performance. Its 153213mm compact dimensions fit small-to-medium spindle structures, while the double-row design significantly enhances radial load capacity and bidirectional axial load resistance—key for maintaining spindle precision during high-speed rotation. The "Z" designation indicates a single-sided metal shield, which effectively blocks dust and debris while allowing optimal lubrication retention, making it suitable for environments requiring both contamination protection and low-friction operation. Crafted from GCr15 high-quality bearing steel, it undergoes precision grinding and superfinishing, ensuring minimal vibration and consistent rotational accuracy—ideal for high-demand spindle systems.
