Bearings Function Provides smooth rotation for shafts by supporting radial and axial loads with predictable clearance, enabling reliable machine operation. Key benefits Reduces friction and wear to extend component life Improves energy efficiency and lowers operating heat Delivers stable, quiet performance with consistent tolerances Compatibility and sizing Available in a range of standard bore sizes and common outer diameters Fits typical shafts and housings with standard mounting arrangements Sealed, shielded, and open variants to suit contamination control and lubrication needs Materials and performance Precisionground steel bearings for dependable durability Stainless steel variants offer corrosion resistance Hybrid and ceramic options for speed or lowfriction requirements load capacity with good dimensional stability across operating temperatures Size and selection Various widths and overall dimensions to match application needs Custom sizes available on request Choose seal type, material, and tolerance based on environment and performance goals Use scenarios Industrial machinery and conveyors: support rollers, gear drives, and rotating shafts Automotive and robotics: wheel hubs, motors, joints, and precision assemblies Home and DIY projects: CNC machines, 3D printers, and power tools requiring reliable rotation How to choose Identify bore (inner diameter), outer diameter, and width Select seal or shield according to dust, moisture, and lubricant exposure Pick material based on load, speed, temperature, and corrosion risk
