1. Bearings Purpose and benefit Bearings reduce friction between moving parts and support radial and axial loads in rotating assemblies. They enable smooth operation, consistent performance, and longer service life in demanding conditions. Why you need them To improve efficiency by lowering torque and energy loss. To maintain shaft alignment and stabilize rotation across speeds and temperatures. Core attributes Function: support rotating shafts with minimal friction and precise motion. Compatibility: designed to fit standard shaft and housing configurations; available in multiple clearance classes and configurations (open, shielded, or sealed) depending on model. Size range: offered in a wide range of bore, outer diameter, and width to fit common shaft sizes. Materials: options typically include standard steel for durability; stainless steel for corrosion resistance; and ceramic hybrids for reduced weight and lower friction at speeds. Performance: engineered for tight tolerances, low friction torque, and reliable operation over expected temperature ranges. Size and fit Bore diameter, outer diameter, and width vary by model; refer to the product table for exact dimensions. Selected to fit conventional housings and shaft interfaces used in industrial and precision applications. Maintenance and care Lubrication requirements depend on model; follow the productspecific lubrication guidelines. Regular inspection for wear, contamination, and lubrication condition is recommended. Seals or shields should be serviced or replaced as required by the operating environment. Applications and use scenarios Industrial machinery: conveyor rollers, pumps, gearboxes, and machine tools requiring reliable rotary motion. Automation and robotics: CNC machines, robotic arms, and precision axis drives that demand smooth, accurate rotation. DIY and small equipment: 3D printers, hobby projects, and garage devices with rotating components needing dependable bearings. Selection considerations Assess load direction and magnitude, operating speed, lubrication method, ambient conditions, and required precision. Ensure compatibility with shaft dimensions and housing standards; consult the model's specifications for exact ratings and limits.
