NTN 1R50X58X30 50mm I.D Needle Roller Bearing Needle Roller Bearing, 58mm O.D

The NTN Needle Roller Bearing with a 50 mm internal diameter, 30 mm inner ring width, and 58 mm under roller diameter is engineered for applications demanding high load capacity and compact design. Its 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.
