The NTN ADLLB series angular contact ball bearing is a component designed to support combined radial and axial loads in a single direction. Its inclined raceway design allows angular contact between the balls and the raceways, giving it a higher axial load capacity than a conventional deep groove ball bearing. It is used in applications requiring precision and rigidity, such as machine tool spindles, pumps, compressors and gearboxes. MR Accesorios Industriales sells this series backed by more than 80 years in the Argentine industrial market.

The ADLLB series designation is interpreted as follows: the initial number indicates the size, which in the examples ranges from 7000 to 7007, corresponding to bore diameters of 10 mm to 35 mm respectively. The letters AD indicate a 25° contact angle, which provides greater axial load capacity. The letters LLB correspond to NTN's specific sealing or internal configuration, which may include shields or a special-material cage. Therefore, when looking for a replacement, it is important to verify that the complete code matches, since each suffix changes the behavior of the bearing.

In Argentine industry, ADLLB series angular contact bearings are used in a wide variety of equipment. They are found in milling machine and CNC lathe spindles, where precision and rigidity are critical. They are also present in process centrifugal pumps, screw compressors, gearboxes and textile machines. Their ability to support axial loads in one direction makes them suitable for applications with constant thrust, such as industrial fans or screw pumps. MR Accesorios Industriales sells them for the replacement and maintenance market.

To correctly select an angular contact bearing, you must consider the magnitude and direction of the loads, the rotation speed and the environmental conditions. The LLB seal protects against contamination and lubricant loss, so it is recommended in dusty or humid environments. Mounting must be done carefully so as not to damage the raceways and respecting the axial clearance recommended by the manufacturer. Lubrication can be with grease or oil, depending on the application, and it is essential to maintain precise alignment between shaft and housing to avoid additional stresses.

When replacing an angular contact bearing, it is common to find equivalences between different brands. For example, an NTN ADLLB series code may have its counterpart in SKF, FAG or NSK, but the letters and numbers may vary. You should not assume that a bearing with similar dimensions is interchangeable, since the contact angle and cage type influence performance. If you have the code from another brand, at MR Accesorios Industriales we can tell you the compatible alternative or quote the exact code you need.
