Rolling Element Bearings:
- Ball bearings: Single- or double-row bearings with balls as rolling elements. Provide low friction and high-speed capability.
- Roller bearings: Bearings with cylindrical, tapered, or spherical rollers. Offer higher load capacities and can handle axial or radial loads.
- Tapered roller bearings: Bearings with conical rollers that handle both thrust and radial loads.
- Needle bearings: Bearings with thin, cylindrical rollers for applications where space is limited.
Sliding Bearings:
- Plain bearings: Bearings with a sliding surface between the shaft and housing. Offer low friction and wear when lubricated properly.
- Hydrodynamic bearings: Bearings that generate a thin film of lubricant between the shaft and housing, providing zero friction.
- Hydrostatic bearings: Bearings that use an externally supplied pressurized lubricant to create a thin film and reduce friction.
Special Purpose Bearings:
- Magnetic bearings: Bearings that use magnetic fields to suspend the shaft, eliminating mechanical contact and friction.
- Air bearings: Bearings that use compressed air to create a lifting force, resulting in low friction and wear.
- Jewel bearings: Bearings with sapphire or ruby jewels as the sliding surfaces. Used in high-precision devices such as watches and compasses.
Hybrid Bearings:
- Ceramic ball bearings: Bearings with ceramic balls for higher temperature resistance and longer life.
- Hybrid roller bearings: Bearings with steel rollers and a ceramic inner or outer race for increased load capacity and reduced friction.
Other Classifications:
- Contact angle: The angle between the radial line and the line of contact between the rolling elements and the raceway.
- Load rating: The maximum load that a bearing can withstand without exceeding a specified amount of deformation.
- Preload: The initial force applied to a bearing to reduce play and improve stability.
- Cages: Devices that separate and guide the rolling elements within a bearing.
