1204 ETN9/C3W64F Bearing Product Overview & Core Advantages
The 1204 ETN9/C3W64F is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Its metric design features a cylindrical bore and open construction, making it suitable for precision arrangements. This bearing is pre-lubricated and features a C3 radial internal clearance, optimized for operational conditions where thermal expansion must be accommodated. The use of a nylon cage contributes to its suitability for high-speed operation, with a limiting speed of 20,000 rpm. Engineered from chrome steel, it offers robust performance in a compact form factor, ideal for demanding industrial environments.

1204 ETN9/C3W64F Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under load. This makes it ideal for applications requiring high rigidity and minimal deformation.
Enhanced Load Capacity: Engineered to handle combined loads (radial and axial forces simultaneously), this bearing's optimized contact angle and dual raceway arrangement distribute stress effectively across both rows of balls, extending service life under demanding conditions.
Superior High-Speed Performance: The ETN9 nylon cage ensures excellent guidance of rolling elements while reducing centrifugal forces at high rotational speeds. Combined with optimized lubrication, this enables reliable operation up to 20,000 rpm.
Pre-Configured for Immediate Use: Factory-applied lubrication and C3 clearance provide immediate operational readiness while accommodating thermal expansion in various operating environments within the specified temperature range of -30° to 110°C.
