NTN ARN angular contact thrust ball bearings are built for axial loading in a single direction together with radial forces. Machine tool spindles, rotary tables and measuring equipment are typical homes for this series, where precision and rigidity matter. MR Industrial Accessories LLC supplies the ARN range to maintenance and purchasing teams in the US and Latin America.
Reading an ARN part number starts with the letters, which mark the angular contact thrust ball bearing family. The digits that follow carry size information such as bore and outer diameter, though the exact breakdown depends on the maker. Part numbers in this range include ARN2062, ARN2572, ARN3080, ARN3585, ARN4090, ARN5090, ARN45105 and ARN50110, each a different size combination. NTN dimension tables are the reference to confirm which one fits.
These bearings suit operations that need controlled axial movement and the ability to carry heavy loads. Metalworking, automotive, aeronautics and machine tool building all rely on them. Common equipment includes milling machine spindles, lathes, grinding machines, and measuring and control devices. Robotics and positioning systems also use them where axial stiffness is a priority.
Choosing the right unit means reviewing the axial and radial loads it will see, the running speed, the precision class required and the lubrication method. Check axial and radial clearance, and plan the mounting so alignment is correct and parasitic loads do not appear. Grease or oil lubrication, applied properly, helps the bearing reach its expected service life.
Interchange with other brands is possible in some cases, but dimensions and load capacities must be compared first. Thrust ball bearings are not universally swappable because contact angles and tolerances differ between designs. Having a specialist review the data avoids a mismatch.
