The NTN Needle Roller Bearing with an internal diameter of 45 mm, inner ring width of 40 mm, and under roller diameter of 55 mm is engineered for applications demanding high load capacity and compact design. The minimum fillet radius of 0.6 mm ensures smooth transitions in the bearing's geometry, reducing stress concentrations. The absence of a lubrication hole on the inner ring may necessitate external lubrication methods to ensure optimal performance. With a precision class of P0, it meets standard tolerances suitable for general-purpose applications.
