The SKF 7321BECBM is a high-quality single row angular contact ball bearing designed for applications requiring high speed and precision. It features a 40° contact angle (B) for high axial load capacity and a machined brass cage (M) for durability and performance. With a bore diameter of 105 mm, an outer diameter of 225 mm, and a width of 49 mm, this bearing is suitable for various industrial machinery where reliable operation under combined radial and axial loads is critical. The 'E' indicates an optimized internal design for increased load carrying capacity, and 'C' signifies a 15° contact angle, though 'B' (40°) is also specified, indicating a specific variant or a combination of features depending on the full designation interpretation.
