NF204EM Cylindrical Roller Bearings 20×47×14mm
The NF204EM bearing is a Cylindrical Roller Bearing with an inner diameter of 20 mm , an outer diameter of 47 mm, a width of 14 mm. It typically uses P0 P5 P6 grade precision tolerances and Open/seal/Single type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Cylindrical roller bearings have exceptionally low friction torque characteristics. That make them suitable for high speed operation. They also have high radial load . Carrying capacity. They are typically used in machine tools, transmissions, Vibration machinery and as wheelset bearings for rail vehicles.
