For mounting bearings and other shaft-mounted components, the NTN AN series lock nut provides axial fastening. It works with a lock washer to resist vibration-induced loosening. This nut plays a key role in both installation and removal of bearings in industrial machinery.
Reading the AN code is straightforward: the letters AN come first, followed by a number that relates to the shaft diameter or nut size. Basic sizes include AN00, AN01, AN02, and AN03. Intermediate sizes such as AN/22, AN/28, and AN/32 use a slash; the digits after it give the thread diameter in millimeters. This numbering helps you quickly match the nut to the shaft and bearing.
These lock nuts appear in food processing, cement, mining, oil, and power transmission operations. You will find them on pumps, gearboxes, fans, conveyor belts, and machine tools. Their job is to hold the bearing's axial position, which simplifies mounting and routine maintenance.
When choosing a nut, confirm the shaft diameter, thread pitch, and lock washer compatibility. Install it with the correct washer and the recommended lubricant to avoid seizing. Proper alignment and tightening torque are essential for bearing life and to prevent early failures.
NTN AN nuts can be interchanged with other brands that use the same designation standard, including SKF, FAG, and NSK, provided dimensions and pitch match. If you have a part number from another brand, we can identify the equivalent. Our team helps you get the right part.
