As an open bearing,the core characteristic of the FAG 6204-C is its flexibility and high performance.The absence of seals minimizes frictional torque,allowing for very high limiting speeds.The open design also allows users to clean the bearing and pack it with special-performance greases(e.g.,high-low temperature grease,food-grade grease,or solid lubricants)before installation.Manufactured using FAG's advanced processes,the rings and balls are super-finished to achieve extremely low surface roughness,ensuring smooth operation with minimal noise and vibration.The stamped steel cage is optimally designed for sufficient strength and flexibility,adapting well to centrifugal forces at high speeds.This bearing is an ideal base component for building high-performance,customized drive systems.

The FAG 6204-C has a bore diameter of 20 mm,an outer diameter of 47 mm,and a width of 14 mm.Its dynamic load rating is 14.0 kN,and the static load rating is 6.55 kN.Being an open design,its limiting speed is as high as 18,000 r/min with grease lubrication and 26,000 r/min with oil lubrication.The radial internal clearance is strictly controlled within the CN(Normal)group range,a universal grade suitable for most operating conditions.The bearing rings and rolling elements are made from high-purity chrome steel(100Cr6)and undergo martensitic hardening,achieving a core hardness of 58-62 HRC,which guarantees excellent wear resistance and fatigue strength.
The FAG 6204-C is primarily used in precision equipment requiring high-speed operation or special lubrication.It is a common bearing in high-speed motor spindles,precision machine tool spindles,high-speed textile machinery(e.g.,spindles),dental handpieces,and turbo-molecular pumps.It is also used in auxiliary systems within the aerospace sector.Due to its open structure,it is often used in central lubrication systems or housed in bearing units with integral seals.Equipment manufacturers choose this type of open bearing as a base platform when they wish to implement their own sealing solutions or use specific high-performance lubricants.
