The NTN Needle Roller Bearing with an internal diameter of 40 mm, a bearing width of 23 mm, and an under roller diameter of 48 mm is a high-performance component designed for applications requiring compact size and high load capacity. With a minimum fillet radius of 0.6 mm and an inner ring chamfer length of 2 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. Weighing approximately 0.092 kg, it is lightweight yet robust.
