SRW156zz Bearing Product Overview & Core Advantages
The SRW156zz is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. Manufactured entirely from stainless steel components, this bearing offers excellent corrosion resistance. Its shielded (ZZ) design provides effective protection against contaminant ingress while maintaining high-speed capability up to 47,700 rpm. The extended inner ring facilitates easier mounting and axial location, making it an ideal solution for applications demanding high precision and consistent radial load capacity in a miniature footprint.
