Barden Bearings 212HCDUM O-11 Radial Ball Bearing

The Barden 212HCDUM O-11 is a high‑precision spindle bearing from the Barden line, a two‑row angular‑contact ball bearing designed for machine‑tool spindles and other demanding precision applications. It features a 60 mm bore, 110 mm outer diameter, and 22 mm overall width with a 15° contact angle, making it well suited for stiff, high‑speed spindle configurations. This O‑11 variant is cataloged as a spindle bearing, engineered for precision machine‑tool environments and capable of supporting substantial radial loads while maintaining tight tolerances in continuous machining. The bearing delivers a dynamic radial load rating of 55 kN and a static radial load rating of 44 kN, reflecting its capability to handle the rigors of milling, drilling, and other precision machining tasks. Designed specifically for spindle assemblies requiring reliable, long‑life performance, the 212HCDUM O‑11 combines exacting geometry, robust load handling, and compatibility with precision machining standards that define Barden’s legacy in super‑precision bearings.
