7409 BGBM Bearing Product Overview & Core Advantages
The 7409 angular contact ball bearing represents a precision-engineered single row solution designed for applications requiring exceptional rotational accuracy and high-speed capability. Manufactured to P6 (ABEC-3) tolerance class, this bearing delivers superior running precision and dimensional stability. Its defining 40° contact angle is optimized to support significant combined loads—handling both radial forces and substantial unidirectional axial thrust simultaneously. The combination of chrome steel rings, chrome steel balls, and a brass cage ensures reliable performance in demanding industrial environments, making it an ideal choice for high-rigidity, precision applications.
