The NTN Needle Roller Bearing with a 45 mm internal diameter, 40 mm inner ring width, and 50 mm under roller diameter is engineered for applications requiring compact size and high load capacity. With a minimum fillet radius of 0.3 mm and an inner ring chamfer length of 1.5 mm, this bearing ensures smooth operation and ease of installation. The absence of a lubrication hole on the inner ring indicates that it is intended for use in environments where external lubrication is sufficient. Classified under precision class P0, this bearing meets standard tolerances suitable for general-purpose applications.
