K30013AR0 Bearing Product Overview & Core Advantages
The K30013AR0 is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its 30° contact angle is optimized to handle significant axial loads in one direction while simultaneously supporting radial loads. Manufactured to ABEC-1 precision tolerances, this bearing delivers reliable operation and excellent rotational accuracy. The compact thin-section design (13mm width) with a 300mm bore makes it ideal for space-constrained applications where high load capacity and precision are paramount.
