Light-Duty Swivel Castor Wheel Assembly drawing with Bearings

This technical drawing illustrates a light-series castor wheel assembly with exploded component views. This design features a swivel mounting plate with integrated needle bearings for smooth rotation and reduced friction. The assembly includes multiple components: a top mounting plate with standard bolt pattern, roller bearing housing, axle components, and a polyurethane or rubber wheel. The castor incorporates needle bearings (DIA2X13) with corresponding race tracks for enhanced load distribution and durability. The exploded view shows the precise relationship between components including the wheel, axle, bearings, housing, and mounting plate. Cross-sectional views reveal internal bearing arrangements and the swivel mechanism design, which enables 360° rotation while maintaining structural integrity. The mounting plate appears to feature a standard 4-bolt configuration for versatile installation applications, with the entire assembly optimized for light to medium-duty applications in commercial or industrial environments.
