NB160AR0 Bearing Product Overview & Core Advantages
The NB160AR0 is a precision angular contact ball bearing designed for demanding applications requiring high accuracy and reliability. Manufactured to ABEC-1 tolerance class, this bearing features a 30° contact angle optimized for handling combined radial and axial loads simultaneously. The Endura-kote chromium plating provides superior corrosion resistance, while the single row construction maintains a compact profile ideal for space-constrained installations. With its chrome steel rings and brass cage, it delivers exceptional performance in high-precision rotational systems.
