Precision bearings feature tighter dimensional tolerances (ABEC 5+), optimized raceway geometry, specialized materials, and controlled preload to minimize rotational error, vibration, and thermal expansion effects critical for accurate angular positioning.
Proper preload eliminates internal clearance, increases stiffness, reduces deflection under load, and improves rotational accuracy but requires careful adjustment to avoid excessive friction, heat generation, and reduced bearing life.
