7411 BGBM Bearing Structural Features & Performance Benefits
Optimized Contact Angle & Load Capacity: The 40° contact angle is engineered to handle substantial one-direction axial loads in combination with radial loads. With a dynamic load rating of 24,975 lbf and a static load rating of 17,212 lbf, it delivers robust performance under demanding conditions.
High-Speed Capability: Featuring a brass cage for superior strength and guidance, the bearing achieves a limiting speed of 8,000 rpm. The open design minimizes friction and heat generation, contributing to its high-speed performance.
Precision Engineering: Manufactured to P6 tolerance from high-grade chrome steel for both rings and balls, the bearing ensures minimal runout and vibration. This makes it suitable for applications requiring high rotational accuracy.
Thermal Stability: The specified temperature range of -30°C to 110°C allows for reliable operation in varied thermal environments, maintaining dimensional stability and preload characteristics.
