The NTN BNS series angular contact ball bearing is built for combined radial and axial loads where rotational accuracy matters. Machine tool spindles, grinding heads and measuring equipment rely on its rigidity and low friction. MR Industrial Accessories LLC supplies this line to customers across the United States and Latin America.
Reading the part number helps you match the bearing to the spindle. The 5S prefix identifies the ball material, 2LA covers sealing or protection, and BNS marks the high-precision angular contact family. The middle digits give the size, while the CLLB suffix defines cage and internal clearance. Examples include 5S-2LA-BNS009CLLB and 5S-2LA-BNS016CLLB. Each block tells you something useful for selection.
These bearings appear in milling and grinding machine spindles, machining centers, precision drill heads, measuring equipment and positioning systems. Their ability to take axial loads in both directions makes them adaptable to different setups. In metalworking shops, auto parts plants and production facilities, they support movements that must be exact and repeatable.
Selection depends on the mounting arrangement. Angular contact bearings are generally installed in pairs with preload set for the application. The 2LA seal keeps contaminants out and lubricant in. Use lubrication suited to the operating speed, and check alignment between housings to avoid extra stress. Careful mounting protects spindle precision and service life.
Equivalent designations from other manufacturers may exist, but prefixes and suffixes differ by nomenclature. For a replacement, confirm the main dimensions, sealing type and internal clearance. MR Industrial Accessories can help you identify a compatible option that maintains original performance.
