1210 ETN9/C3 Bearing Product Overview & Core Advantages
The 1210 ETN9/C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigidity. This precision bearing excels at handling combined loads, simultaneously supporting significant radial forces and axial loads in both directions. Its compact design, featuring a 20 mm width, makes it ideal for space-constrained, high-reliability machinery. The optimized internal geometry and C3 radial internal clearance ensure stable performance under varying operational conditions, making it a robust choice for demanding industrial environments.

1210 ETN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to handle substantial combined loads. With a dynamic load rating of 5962 lbf and static load rating of 2059 lbf, it delivers reliable performance in high-stress applications.
High-Speed Performance: The TN9 nylon cage reduces centrifugal forces and friction, contributing to a high limiting speed of 10,000 rpm. This makes it an excellent choice for high-speed applications.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion and interference fits, ensuring consistent performance across the operating temperature range of -30°C to 110°C.
Material Quality: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance, ensuring long service life.
