For machinery where radial space is at a premium but radial loads are heavy, the NTN NA series needle roller bearing delivers a compact solution. It is a single-row radial bearing with a machined inner ring and a steel cage. Typical installations include gearboxes, pumps, compressors and textile equipment, where the relationship between load capacity and cross section is a key design factor. MR Industrial Accessories supplies this series and can help you match the right designation to your application.

The part number tells you a lot if you know how to read it. The letters NA mean a needle roller bearing that includes an inner ring. The digits that follow describe the size. In NA498CT, the 49 is the dimension series, while CT is a suffix for cage or treatment variations. In NA5902CT, the 59 points to a different series of diameters and widths. Suffixes like CT can signal changes to the cage, sealing or internal clearance. Because these codes are not always obvious, it pays to confirm the full designation with a specialist before ordering.

You will find these bearings in industries that combine high radial loads with limited space. They are common in automotive plants, machine tools, mining equipment, cranes and transmission systems. Water pumps, air compressors and food processing machinery also use them. Their ability to carry radial loads with a minimal section makes them suitable when other bearing types will not fit.

Selection depends on three main factors: radial load, rotation speed and the space available. If the bearing does not have an inner ring, check that the shaft has the correct hardness and roughness to act as a raceway. Lubrication is critical—choose a grease or oil that handles the temperature and speed of your operation. Mounting calls for an interference fit on the outer ring and controlled radial clearance. Keeping the shaft and housing aligned avoids parasitic axial loads that shorten service life.

NTN NA series bearings can be interchanged with other brands that follow the same standardized dimensions. If you have a competitor's code, we can identify the equivalent. Interchangeability depends on tolerances and internal clearance, so always verify the specifications. We help you find the right replacement while maintaining original performance.
