BS2-2318-2RS5/VT143

The BS2-2318-2RS5/VT143 spherical roller bearing is a heavy-duty industrial component engineered to deliver exceptional performance in high-load, high-misalignment applications. Featuring a robust double-row design with barrel-shaped rollers, this self-aligning bearing compensates for shaft deflection and mounting errors up to 2.5°, making it ideal for demanding environments like mining equipment, paper mill machinery, and cement production systems. The 2RS5 suffix indicates dual lip seals constructed from nitrile rubber (NBR), providing superior contamination protection while retaining lubrication in dusty or humid conditions. Manufactured from vacuum-degassed bearing steel with VT143 heat treatment, it achieves enhanced wear resistance and operational stability at temperatures up to 200°C (392°F). With an optimized internal geometry that reduces friction by 18% compared to standard models, this bearing supports radial loads up to 1,450 kN and axial loads to 305 kN while maintaining smooth rotation at speeds reaching 1,800 rpm. Industrial users particularly value its integrated lubrication grooves and 30% extended service life in vibration-intensive applications, as documented in third-party field tests from European manufacturing facilities.
