Ball Bearings vs. Roller Bearings: Key Differences & Applications
Introduction While both ball and roller bearings reduce friction, they serve different purposes depending on load capacity and application requirements. Understanding their differences helps in selecting the right bearing for specific machinery. What Are Ball Bearings? Ball bearings consist of steel balls that rotate between inner and outer rings , reducing friction and enabling smooth movement. They are best suited for light to moderate loads and high-speed applications . What Are Roller Bearings? Roller bearings use cylindrical, tapered, or spherical rollers instead of balls , providing better load distribution. They are ideal for heavy loads and low-speed applications . Key Differences Between Ball Bearings & Roller Bearings Feature Ball Bearings Roller Bearings Load Type Radial & Axial Mainly Radial Speed High-speed Low-speed Friction Low Higher due to larger contact area Durability Moderate High for heavy loads Applications Automotive, electric motors Industrial ma...
