The RICH 61904-2RS C3, also commonly known as 6904-2RS C3, is a high-performance single row deep groove ball bearing designed for applications requiring robust sealing and a higher than normal radial clearance. This bearing embodies RICH's commitment to delivering precise and durable solutions for various industrial and automotive systems.

With precise dimensions of 20 mm inner diameter, 37 mm outer diameter, and a 9 mm width, the 61904-2RS C3 RICH is ideally suited for electric motors, bicycles, pumps, and other machinery where reliable operation in contaminated environments or under conditions of thermal expansion is critical. Its deep groove geometry allows it to efficiently accommodate both radial and axial loads. The C3 clearance indicates a greater than normal internal radial clearance, which is beneficial for applications involving high speeds, significant temperature differences between the inner and outer rings, or those where press fits on both rings are required. The double-sided rubber seals (2RS) provide excellent protection against dust, dirt, and moisture ingress, while also retaining the internal lubrication for an extended and maintenance-free service life. Manufactured in China, this RICH deep groove ball bearing ensures consistent quality and dependable performance, providing a trustworthy solution for demanding applications.

Key Performance Advantages:

• C3 Clearance: Optimized for high-speed operation or applications with thermal expansion.
• Robust Sealing (2RS): Provides excellent protection against contaminants and retains lubricant, extending bearing life.
• Versatile Load Handling: Effectively accommodates both radial and axial loads.
• Durable Construction: Designed for reliable performance in various operating conditions.
• RICH Quality: Produced in China, ensuring consistent quality and dependable performance.
