Description

The BCA Bearing NB3994 is a tapered roller bearing designed for light- and medium-duty applications. It features a case carburization process that results in a hard, wear-resistant outer shell and a tough, ductile core. This precision-engineered bearing is constructed from quality materials to ensure optimal performance and durability.

The tapered roller bearing offers excellent shock-resistant properties and a longer life compared to through-hardened product offerings. It is capable of handling radial, axial, and combined loads, making it suitable for common applications such as transmissions, engines, differentials, wheel ends, and transfer cases.
