FV bearings have received a large order for rolling mill bearings from European users. This batch of bearings is designed and manufactured according to SKF's TQON/GW. This is a design without spacer ring. Reduced the difficulty of user installation and the probability of incorrect installation. The ring material of BT4-0004 G/HA1 four row tapered roller bearing is SAE4320H (G20CrNi2MoA) carburizing steel, which is a high-purity and high-performance bearing steel. After carburizing and quenching, the raceway hardness of the bearing reaches HRC60+, and the hard martensite makes its surface super wear-resistant. The use of carburized steel to manufacture this type of bearing is the foundation of long service life. Not comparable to those low-priced and low-quality bearings. This is a responsible behavior towards users.
This batch of orders is currently undergoing precision grinding processing. Our IT engineers will update the progress as soon as possible. Ultimately, we will showcase the most perfect rolling mill bearings to the world.
The interchangeable models are: 330758A, M257248DGW-210-210D, MSTF304KV4153
