  BS2 sealed self-aligning roller bearing

Sealed self-aligning roller bearings can be widely used in places with relatively harsh environment, such as iron and steel metallurgy, mining, petrochemical, paper making, cement manufacturing and other engineering machinery fields. Sealed end caps are provided to effectively protect the internal structure of the bearing from external damage, extend the service life of the bearing, and enable the bearing to operate for a long time under high temperature, high pressure, heavy load and other complex environmental conditions.。
21311-2CSSealing of，Almost no friction heat is generated during work，Small wear，Especially suitable for high-speed and high-temperature occasions。
