7204 BECBM Bearing Product Overview & Core Advantages
The 7204 BECBM is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. This metric bearing features a 40° contact angle, enabling it to effectively handle both radial loads and substantial axial loads in one direction. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The brass cage ensures reliable operation at high speeds, while the open design facilitates optimal lubrication management for demanding applications.
