Bearings What it does Supports rotating or sliding parts to reduce friction and wear. Carries radial and/or axial loads so mechanical components run smoothly and reliably. Why you need it Improves efficiency by lowering friction and heat generation. Extends component life through precise support and reduced wear. Reduces noise and vibration for quieter operation and better user experience. Simplifies maintenance when selecting sealed or prelubricated options. Key benefits and attributes Function: Provides accurate, lowfriction rotation for shafts, axles, and moving components. Compatibility: Works with a wide range of housings and shaft sizes when the correct bearing type and dimension are selected. Size: Available in multiple bore and outer diameters; choose the size that matches your shaft and mounting space. Material: Manufactured from common bearing materials suitable for different environments; material choice affects load capacity and corrosion resistance. Performance: Offers options for different speeds, loads, and precision levels; proper selection balances speed capability, load capacity, and durability. Sealing and lubrication: Sealed bearings reduce contamination and maintenance; open bearings allow relubrication for extended service life. Load types: Select bearings rated for radial loads, axial loads, or combined loads depending on application. How it solves common problems Prevents premature shaft wear by maintaining alignment and reducing metalonmetal contact. Minimizes downtime by choosing sealed or prelubricated bearings for dirty or inaccessible environments. Matches performance requirements (speed, load, life) by selecting appropriate bearing type and tolerance class. Typical use scenarios Electric motors and pumps: Supports motor shafts for smooth rotation, lowers friction losses, and improves motor life. Materialhandling equipment and conveyors: Handles continuous rotational loads and reduces maintenance intervals in industrial settings. Small machinery, bicycles, and hobby projects: Provides dependable rotary support for wheels, spindles, and rotating assemblies. Selection tips Verify shaft diameter and housing bore before ordering. Match bearing type to load direction (radial vs axial) and expected operating speed. Consider environmental exposure (moisture, dust) when choosing sealed vs open bearings. Check lubrication requirements and relubrication intervals for longterm reliability. Installation and maintenance notes Ensure shafts and housings are clean and within tolerance before installation. Use proper mounting tools to avoid bearing damage from hammering or misalignment. Follow lubrication recommendations and inspect periodically for noise, heat, or play. Reliable choice when you need precise, lowfriction rotational support.
