Here are 5 common types of bearings, categorized based on their structure and function:
1.Ball Bearings
Use spherical rolling elements (balls) to reduce friction.
Examples: Deep groove ball bearings, angular contact ball bearings.
Ideal for high-speed, low-load applications like electric motors.
2.Roller Bearings
Use cylindrical, tapered, or spherical rollers instead of balls.
Subtypes:
Cylindrical roller bearings (handles heavy radial loads).
Tapered roller bearings (supports combined radial/axial loads, e.g., car wheels) .
Designed to handle axial (thrust) loads, often in vertical shafts.
Includes thrust ball bearings (for lighter loads) and thrust roller bearings (heavier loads) .
Operate via sliding friction without rolling elements.
Used in low-speed, high-load scenarios (e.g., engine crankshafts) .
5.Specialized Bearings
Needle Bearings: Thin rollers for compact spaces (e.g., automotive transmissions)
Magnetic or Fluid Bearings: For ultra-high-speed or precision applications (e.g., turbines)
