💡 What is a spherical roller bearing used for in heavy machinery?

They’re handy for supporting heavy loads and allowing for shaft misalignment in rugged equipment.

• They take radial and axial loads in both directions
• They tolerate shaft deflection with low friction
• They work with housings and modular bearing systems
• They provide long service life in harsh operating conditions
