roller wheel 3d model

A CAD-grade 3D model of a high-load mechanical roller wheel designed for a sliding door system. The geometry is a precise body of revolution. The maximum outer diameter (OD) is exactly 48mm. It features a concave, semicircular groove (U-groove) profile machined into the outer circumference, with the groove's deepest seating diameter being exactly 42mm, perfectly shaped to ride on a corresponding circular rail. The total thickness (width) of the wheel is 11mm. At the center, there is a precision-bored through-hole acting as a bearing pocket, with an internal diameter (ID) of exactly 22mm to accept a press-fit standard bearing (e.g., 608 series). The edges of the outer diameter and the bearing pocket should have a minor 0.5mm chamfer for assembly lead-in. The surfaces must be clean and manifold. Rendered in a matte engineered plastic finish (like Delrin or PA6) with smooth geometry."
