Self Aligning Spherical Roller Bearing 21304 CDE4C3S11 NSK With 20 Mm Inner Diameter 52 Mm Outer Diameter And 15 Mm Width Cylindrical Bore C3 Clearance For Heavy Load Applications

High-precision spherical roller bearing 21304, C3 bore
✔️ ID 20 mm, OD 52 mm, width 15 mm, cylindrical bore, single unit

The 21304 spherical roller bearing with C3 clearance is a robust, self-aligning solution designed to handle heavy loads in both directions. Manufactured to precision tolerance classes by NSK, it’s commonly used in conveyors, presses, rolling mills, and other heavy machinery where shaft deflection and misalignment occur.

✅ Heavy radial and axial load capacity in both directions
✅ Self-aligning design tolerates misalignment and shaft deflection
✅ Precision tolerance class for demanding industrial applications
✅ Robust steel cage construction for long-term durability
✅ C3 clearance provides extra room for thermal expansion and misalignment

💡 What is a spherical roller bearing and where is it commonly used?

That handy bearing type handles heavy loads and misalignment in tough industrial settings. - handles heavy radial and axial loads in both directions - tolerates shaft misalignment and deflection with low friction - used in conveyors, rolling mills, crushers, and metal forming equipment - choose appropriate clearance such as C3 for performance under temperature changes
