Deep Groove Ball Bearing

Expansion compensating deep groove ball bearing

The expansion compensating deep groove ball bearing is a specialized type of deep groove ball bearing designed to accommodate thermal expansion in applications where temperature variations are significant. These bearings typically feature an inner ring with an elongated bore, allowing for axial movement of the shaft relative to the bearing. This design helps to prevent excessive preload or misalignment that could occur due to thermal expansion of the shaft or housing. Expansion-compensated deep groove ball bearings are often used in equipment subject to temperature fluctuations, such as industrial ovens, kilns, and machinery operating in special environments. They help maintain proper clearance and alignment between rotating components, thereby extending bearing life and improving overall system reliability.
