1. Bearings Function and benefits A bearing supports a rotating shaft, allowing smooth motion with minimal friction while carrying radial and axial loads. This reduces energy loss, lowers heat generation, and extends the life of connected components, helping maintain precision and reliability in moving parts. Key attributes Range of sizes to fit common shaft diameters, available in metric and inch sizes. Material options typically include grade steel for races and balls, with stainless steel variants for corrosion resistance. Designs available include open, shielded, and sealed types to match operating conditions. Suitable for a variety of temperatures and environments. Performance Engineered for low torque and consistent rotation. Precision tolerances support stable runout and dependable load handling from light to heavy applications. Seals and shields help protect against contaminants and extend service life. Compatibility and installation Designed to fit standard bearing housings and mounting configurations. Compatible with common adapters, spacers, and seals used in typical equipment. Installation should follow manufacturer guidelines, with attention to correct lubrication, alignment, and seating to ensure performance. Size and materials overview Bearings are available in a wide size spectrum to accommodate different shaft diameters and space allowances. Standard options use steel races and balls; stainless steel variants offer corrosion resistance for damp or outdoor environments. Some lines provide ceramic variants for specialized lowfriction needs. Use scenarios 1) Industrial conveyors and packaging lines where rollers require smooth, reliable rotation and reduced maintenance. 2) Precision machinery such as CNC machines or milling setups that demand stable rotation and minimal runout. 3) Power tools and light machinery in workshop or garden applications that operate under varying loads and speeds. Care and maintenance tips Select the appropriate bearing type (open, shielded, or sealed) for the environment. Use the recommended lubricant and relubrication schedule. Inspect seals and shields for damage, check alignment, and bearings if there are signs of wear, unusual noise, or reduced performance. Store bearings in clean, dry conditions to prevent contamination.
