📝 Category Detail

7200B series are high-performance single-row angular contact ball bearings engineered with a 40° contact angle, delivering exceptional unidirectional axial load capacity and high rigidity for heavy-duty applications. Compared to 15° (C-type) and 25° (AC-type) variants, the B-series offers superior thrust load performance, making it ideal for vertical mounting, high-axial-force machinery, and precision transmission systems.

Manufactured from premium GCr15 (100Cr6) high-carbon chromium bearing steel with strict vacuum degassing and precision heat treatment, these bearings ensure excellent wear resistance, dimensional stability, and long service life. Available in multiple cage designs (BTN nylon cage, BM brass cage) to meet different speed and load requirements, they support paired installation (DB/DF/DT) for bidirectional axial load applications, with standard metric dimensions for global interchangeability with international brands.
