Precision mechanical component that reduces friction between rotating parts and supports radial/axial loads in industrial machinery.
A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. The design of the bearing may provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or the directions of the loads (forces) applied to the parts.

Ball bearings use spherical rolling elements and are optimized for high-speed applications with moderate loads. Roller bearings use cylindrical, tapered, or spherical rollers and handle higher radial/axial loads at lower speeds due to larger contact areas.
Lubrication intervals depend on operating conditions: typically 3-12 months for grease-lubricated bearings in standard applications. High-speed or high-temperature applications may require continuous oil lubrication or more frequent greasing. Follow manufacturer specifications and monitor condition.
Common causes include improper installation (25%), contamination (20%), inadequate lubrication (35%), overload (10%), and misalignment (10%). Regular maintenance, proper handling, and correct installation procedures can prevent most failures.
