ND055AR0 Bearing Product Overview & Core Advantages
The ND055AR0 is a single row angular contact ball bearing engineered for precision applications requiring high load capacity and dimensional stability. Featuring an Endura-Kote chromium plating surface treatment, this bearing offers enhanced corrosion resistance while maintaining critical thin-section bearing dimensions (5.5" bore × 6.5" OD × 0.5" width). Its optimized 30° contact angle provides superior combined load capacity, effectively handling both radial and axial loads simultaneously. Manufactured to ABEC-1 precision standards, this bearing delivers reliable performance in demanding industrial environments.
