NTN 1R50X58X40 50mm I.D Needle Roller Bearing Needle Roller Bearing, 58mm O.D

The NTN Needle Roller Bearing with an internal diameter of 50 mm, inner ring width of 40 mm, and under roller diameter of 58 mm is designed for applications requiring high load capacity and compact dimensions. 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.
