The FAFNIR 7316 WNSU is a high-performance single row angular contact ball bearing designed for applications demanding exceptional rigidity, high speeds, and accurate shaft guidance. Featuring bore dimensions of 80 mm, an outer diameter of 170 mm, and a width of 39 mm, this bearing incorporates a 40° contact angle (B equivalent), optimizing it for heavy combined radial and axial loads. The WNSU designation signifies a robust pressed steel cage (W) and critical Universal Matching (U) capability, ensuring that individual bearings are manufactured to tight tolerances allowing for flexible mounting configurations (Duplex O, X, or Tandem) without requiring shims or special adjustments, thereby simplifying installation and inventory management.
Built for reliability in demanding industrial environments, the 7316 WNSU excels in machine tool spindles, high-speed pumps, industrial compressors, and precision gearboxes where bearing accuracy is paramount. Its non-separable design ensures high stability under load, and the optimized internal geometry facilitates low operating temperatures and extended service life. Choosing the 7316 WNSU provides customers with a reliable, high-precision component that guarantees consistent performance and maximum operational uptime, especially when configuring precise, preloaded bearing sets.
