BS2 Series Spherical Roller Bearings

Description

Product Overview

BS2 Series Spherical Roller Bearings are high-performance, sealed spherical roller bearings designed for demanding heavy-duty applications in harsh and contaminated environments.

This series integrates advanced sealing technology to provide excellent resistance against dust, water, and external contaminants, significantly improving operational reliability and extending service life in extreme working conditions such as mining, crushing, and vibrating machinery.

Manufactured from high-purity vacuum-degassed bearing steel and processed with precision heat treatment (including Aichelin salt bath treatment), BS2 bearings deliver stable hardness, high wear resistance, and consistent mechanical performance under continuous heavy load operation.
