The bearing seat provides precise geometric alignment and secure mounting for bearings, ensuring optimal load distribution, rotational accuracy, and vibration damping in spindle systems.
Material choice impacts dimensional stability, thermal expansion characteristics, damping capacity, and wear resistance. Cast iron offers good vibration damping, while alloy steel provides higher strength for heavy loads.
Common failures include bore wear from bearing creep, thermal deformation, fatigue cracking under cyclic loads, and corrosion in harsh environments, all leading to bearing misalignment and reduced spindle accuracy.
