K05008AR0 Bearing Product Overview & Core Advantages
The K05008AR0 is a metric thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim mm Metric Bearings series, this single row bearing excels in handling combined radial and axial loads simultaneously, thanks to its specified 30° contact angle. Its compact cross-section (8mm width) makes it ideal for lightweight, high-precision assemblies where rigidity and accurate rotational motion are critical. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance in demanding operational environments.
