The attached image shows a 3D model of a bush coupling (also called a bushing or resilient pin-and-bush coupling), consisting of two flanges connected by a central shaft with elastomeric bushings that allow limited articulation and absorb shocks. This design is commonly used in truck-trailer fifth wheel systems, pintle hooks, or drawbar couplings to handle […]

Cup needle roller bearing assembly (likely a full complement type without a cage), featuring thin cylindrical rollers arranged radially within an outer thin-walled shell, with inner ring details and precise dimensions labeled (e.g., outer diameter around 170mm). This design supports high radial loads in compact spaces, making it suitable for truck and trailer applications like
