7412 BM Bearing Product Overview & Core Advantages
The 7412 BM is a single row angular contact ball bearing designed for applications requiring high precision and reliability. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 40° contact angle for optimal axial load capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The open design with brass cage enables high-speed operation up to 7,500 rpm, making it ideal for precision machinery where rigidity and rotational accuracy are critical.
