Technical Details and Specifications

This NSK wheel bearing and hub assembly (part number 47BWKH02L) is engineered to meet the exact specifications required for Acura and Honda Civic and CSX models. The assembly is non-driven, meaning it is designed for the non-driven axle side. It features a magnetic encoder ABS tone ring integrated into the hub, which works seamlessly with the vehicle’s ABS system to provide reliable wheel speed data. The bolt circle diameters for both the mounting flange (100 mm) and wheel flange (114.3 mm) ensure proper fitment and secure mounting. The flange includes four bolt holes sized M10x1.25, while the wheel flange supports five wheel studs sized M12x1.5, providing a secure connection to the wheel. The brake pilot diameter of 64 mm and hub pilot diameter of 70 mm help center the assembly accurately on the axle hub.
