SB047AR0 Bearing Product Overview & Core Advantages
The SB047AR0 is a Reali-Slim Stainless Steel thin section bearing designed for applications requiring compact design and high precision. This single row angular contact ball bearing excels in handling combined loads, featuring a 30° contact angle that provides superior axial load capacity while maintaining excellent radial load performance. Manufactured entirely from stainless steel with a brass cage, it offers exceptional corrosion resistance and reliable operation in demanding environments. The bearing's thin cross-section design makes it ideal for space-constrained applications where weight reduction is critical.
