Angular contact ball bearings (most common), cylindrical roller bearings, and tapered roller bearings, selected based on speed, load, and precision requirements.
Preload eliminates internal clearance, increasing stiffness and rotational accuracy but requires careful adjustment to prevent overheating and reduced bearing life.
Grease lubrication for moderate speeds, oil-air or oil-mist systems for high-speed applications, and minimal quantity lubrication (MQL) for precision environments.
