Bearing 55х90х18 6011

The 6011 bearing is an open, single-row radial ball bearing designed for applications requiring maximum speed and efficiency.Inner diameter: 55 mmOuter diameter: 90 mmWidth: 18 mmType: Single-row radial ball bearingGOST 111 equivalentDynamic rated load (C): approximately 28.1 kNStatic rated load (C0): approximately 21.2 kNThe bearing has an open design, ensuring its durability: Protection: Open bearing (without seals or shields). This allows for the highest possible speeds and facilitates maintenance and lubrication.Design: The absence of seals ensures minimal friction. Requires external lubrication and protection from contaminants in the bearing assembly.Maintenance: Requires regular lubrication or replacement, depending on operating conditions.Loads: The raceway geometry allows the bearing to effectively accommodate high radial loads, as well as significant axial (thrust) loads in both directions.Application: 6011 is widely used in high-speed applications such as machine tool spindles, gearboxes, and electric motors, where an external seal or oil bath is required.
