3D Nut and Bearing CAD Block with Flange Base and Shaft Housing

This 3D Nut and Bearing CAD Block DWG file presents a detailed mechanical housing designed for shaft support and rotational systems. The model features a central cylindrical bore for accurate shaft placement, a raised collar for bearing seating, and a stepped circular profile for structural stability. Two extended mounting arms with evenly spaced fixing holes allow secure installation on machine frames and base plates. A side lubrication port is included to support smooth operation and routine maintenance. Dimensional elements such as bore diameter, flange thickness, base width, mounting hole spacing, and collar height are maintained in proper proportion for fabrication and assembly reference. The isometric view improves visualization of structural form and connection points. This file supports faster modeling, consistent dimensional accuracy, and professional-quality mechanical design workflows.
