2204 Bearing Product Overview & Core Advantages
The 2204 metric double row ball bearing represents a precision bearing solution engineered for applications requiring compact design and reliable performance. This sealed bearing is constructed with two rows of balls, enabling it to handle significant combined loads—both radial and light axial loads in both directions. Its high rigidity makes it ideal for precision machinery and equipment where shaft stability is critical. Pre-lubricated and featuring integral seals, this bearing offers long service life with minimal maintenance requirements.

2204 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides enhanced stiffness and load distribution, allowing the bearing to withstand substantial radial dynamic load ratings of 2858 lbf while maintaining dimensional stability under operating conditions.
Optimized Speed Performance: The lightweight nylon cage minimizes centrifugal forces, enabling the bearing to achieve limiting speeds up to 10,000 rpm while maintaining smooth rotation and reduced vibration.
Maintenance-Free Operation: The integrated sealing system effectively retains lubricant and excludes contaminants, while the pre-applied high-quality grease ensures consistent performance throughout the bearing's service life without requiring re-lubrication.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, this bearing delivers consistent performance and extended service life in demanding applications.
