Spherical roller bearings are designed to support substantial radial and axial loads simultaneously, with a self-aligning capability that compensates for shaft misalignment and deflection with minimal friction or heat generation. Their robust construction ensures excellent performance even in equipment subject to vibration, while features for convenient relubrication and compatibility with modular components such as housings, sleeves, and nuts make them versatile for a wide range of applications. These bearings offer high load-carrying capacity, low friction, long service life, and increased wear resistance.
