NC250AR0 Bearing Product Overview & Core Advantages
The NC250AR0 is a single row angular contact ball bearing featuring Endura-kote chromium plating for enhanced corrosion resistance. Engineered to handle combined radial and axial loads simultaneously, this precision component offers a 30° contact angle for optimal thrust capacity. Its thin-section design (0.375" width) provides space-saving solutions while maintaining high performance in demanding applications requiring ABEC-1 precision tolerance.
