Bearings Function and purpose Bearings enable smooth rotation or linear motion between moving parts by reducing friction and supporting loads. They help machines run efficiently, with less wear and lower energy consumption. Key benefits Reduce friction for smoother operation and improved efficiency. Support radial and axial loads to keep moving parts aligned and stable. Extend component life by minimizing wear and heat buildup. Adapt to different environments with material and seal options. Easy to and to install with standard shaft and housing interfaces. Attributes and specifications to consider Function Designed to provide reliable rotation or translation with minimal resistance across varying loads. Compatibility Available in designs that fit standard shaft sizes and common housing bores. Suitable for metric and imperial sizing families and a range of mounting configurations. Size Offered in a wide range of bore, outer diameter, and width to match different applications. Verify bore size, outer diameter, and width to ensure a proper fit. Material Common options include carbon steel and stainless steel for durability and corrosion resistance. Ceramic variants or ceramic balls available for speed or special conditions. Seals and shields available to protect against dust, moisture, and contaminants. Performance Precision and tolerance classes appropriate for reliable operation. speed capability for fastmoving components. Sealed or greasefilled variants to reduce maintenance needs and protect lubrication. Corrosion resistance for challenging environments and temperature considerations. 23 practical use scenarios Industrial machinery Used in conveyor rollers, gearboxes, and drive systems to reduce friction, handle loads, and improve efficiency. Robotics and automation Employed in robot joints and actuators to provide smooth, precise movement and reliable load support. Automotive and power tools Applied in electric motors, fans, and tool housings to lower energy loss, extend service life, and enable quiet operation. Guidance for selection and installation Choose a bearing that matches the load type (radial, axial, or combined) and operating speed. Select material and seal/shield options based on environment (corrosion risk, dust exposure, temperature). Confirm compatibility with the shaft and housing dimensions (bore, OD, width) and mounting method. Install on clean, dry surfaces; apply appropriate lubrication if not a sealed or greased variant; avoid overtightening and ensure proper seating.
