1. Bearings Why you need them Facilitate smooth rotation of shafts by reducing friction Support radial and axial loads to maintain alignment and prolong equipment life Help improve efficiency, quiet operation, and overall performance of machines and tools What makes them stand out Broad range of bore sizes, outer diameters, and widths to match standard housings and shafts Multiple material options for different environments and speeds Availability in sealed and lubricated variants to minimize maintenance and extend service life Key attributes Function: support rotating components with low friction and controlled clearance Compatibility: designed to fit common shaft and housing configurations in metric and inch sizes Size: available across a wide spectrum of bore, outside diameter, and width to suit various applications Material: options include chrome steel, stainless steel, and ceramic variants for speed or corrosion resistance Performance: engineered for load capacity, low wear, consistent tolerances, and reliable longterm operation Types commonly available Ball bearings for general purpose and speed applications Roller bearings for higher load capacity in axial and radial directions Thrust bearings for axial load support in rotating assemblies Sealed or shielded and pre lubricated variants for reduced maintenance Use scenarios (2–3 practical examples) Industrial conveyors and gearboxes: enable smooth and reliable rotation under varying loads Automotive assemblies and motor systems: provide stable shaft support with predictable performance Workshop equipment and fabrication tools (CNC machines, 3D printers, power tools): contribute to precision, reduced noise, and longer service life How to select Determine bore size (inner diameter), outer diameter, and width to fit your housing Choose material based on speed, environment, and corrosion considerations Decide between sealed, shielded, or open variants based on contamination exposure and maintenance preferences Consider required tolerances and preload specifications for precise alignment and performance
