1.Bearings Purpose: Reduces friction and wear to enable smooth rotation of shafts. Provides support for radial and axial loads depending on configuration. Compatibility and sizing: Available in a range of inner diameters, outer diameters, and widths to fit standard shaft sizes and mounting footprints. Materials and construction: Constructed from durable bearing materials. Variants use steel or stainless steel races with ceramic balls or polymer cages as applicable. Performance: Designed for low friction torque, reliable speed capability, and long service life under typical operating conditions. Corrosion resistant variants available. Use scenarios: Industrial equipment such as conveyors, motors, and gear drives. Household appliances including fans and washing machine components. Robotics, automation, and 3D printing projects requiring precise, quiet rotation. Maintenance and installation: Choose sealed or shielded options as needed; proper lubrication and alignment are essential for life.
