7328 BCBM Bearing Product Overview & Core Advantages
The 7328 BCBM is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. Engineered to accommodate significant axial loads in one direction along with radial loads, this bearing features a 40° contact angle that provides excellent axial load capacity and rigidity. Manufactured to P6 (ABEC-3) tolerance class, it ensures precise rotational accuracy and dimensional stability. The open design allows for optimal lubrication management, making it suitable for high-speed applications up to 3,000 rpm while maintaining consistent performance across a temperature range of -30° to 110°C.
