The 6011 Open is a flexible, Unsealed Single-Row Deep Groove Ball Bearing designed for applications requiring user-controlled lubrication and peak rotational capability. Without integrated seals or shields, this bearing delivers minimal internal resistance, enabling elevated operating speeds and allowing operators to apply specialized lubricants matched to their unique environmental demands. Measuring 55 mm in bore, 90 mm in outer diameter, and 18 mm in width, it falls under the 6000 "Extra Light" ISO series, providing a streamlined radial solution for machinery where external housing seals handle contamination control.
