1 Bearings Function and benefits Reduces friction between moving parts to enable smooth rotation Supports radial and axial loads in rotating assemblies Improves efficiency and helps extend the life of equipment through wear resistance Available in multiple configurations to match different applications Compatibility and sizing Inner diameter (ID) matches the shaft size; outer diameter (OD) fits the housing bore Width and overall dimensions determine load capacity and fit Tolerances and precision grades vary by model; consult the spec sheet for exact figures Materials and performance Common materials include chrome steel, stainless steel, and ceramic hybrids Precision races and balls provide low friction and consistent performance Sealed or shielded variants protect against dust and contaminants Designed for reliable operation under typical industrial and mechanical loads Key specs to verify ID, OD, and width to ensure correct fit Dynamic load rating and static load rating for expected service Seal type, lubrication status (prelubricated or userlurnished) Installation and maintenance Install with proper alignment and correct mounting tolerances Apply lubrication per the model specification if not prelubricated Regular inspection for wear, seals integrity, and lubrication levels Use scenarios 1) Electric motors, gearboxes, or spindles that require smooth rotation and low heat generation 2) Automotive wheel hubs or bicycle hubs needing reliable radial support and long service life 3) Robotics joints or conveyor rollers where consistent motion and predictable maintenance intervals are important Why choose these bearings Proven design suitable for standard shaft sizes and housings Availability in common materials and configurations to match a range of applications Clear specification data to help you select the correct model for your needs
