The NTN Needle Roller Bearing with an inner ring, featuring an internal diameter (d) of 40 mm, a bearing width (B) of 34 mm, and an under roller diameter (F) of 45 mm, is designed to accommodate high radial loads in compact spaces. With a minimum fillet radius (rs) of 0.3 mm and a chamfer length (t) of 2 mm on the inner ring, this bearing ensures smooth operation and easy installation. The absence of a lubrication hole on the inner ring suggests that it is intended for applications where external lubrication is sufficient. Classified under precision class P0, this bearing meets standard tolerances suitable for general-purpose applications. Weighing approximately 0.088 kg, it is lightweight yet robust.
