For equipment that combines radial and axial thrust in one direction, the NTN ADLLB series angular contact ball bearing is a common choice. Its inclined raceways create angular contact between balls and rings, which gives it more axial capacity than a standard deep groove ball bearing. You will find this series in machine tool spindles, pumps, compressors and gearboxes where precision and rigidity matter. MR Industrial Accessories supplies the series to maintenance and purchasing teams across the United States and Latin America.

Reading the code helps you order the right part. The leading number is the size: in this series it runs from 7000 to 7007, which correspond to bore diameters of 10 mm through 35 mm. The letters AD set a 25° contact angle for greater axial capacity. LLB identifies NTN's sealing or internal configuration, which may involve shields or a special-material cage. Because every suffix affects how the bearing performs, match the complete code when replacing.

Typical installations include milling machine and CNC lathe spindles, process centrifugal pumps, screw compressors, gearboxes and textile machinery. Where thrust acts constantly in one direction, such as industrial fans or screw pumps, the one-direction axial capability fits the job. These are maintenance and replacement items for plants that need to keep production running.

Selection comes down to load magnitude and direction, rotation speed and the operating environment. The LLB seal helps against contamination and lubricant loss, so it suits dusty or humid areas. During mounting, work carefully to avoid damaging the raceways and follow the manufacturer's axial clearance recommendation. Grease or oil lubrication is possible depending on the application, and precise shaft-to-housing alignment is essential to prevent extra stress.

Cross-brand equivalents are common, but similar dimensions alone do not make a bearing interchangeable. Contact angle and cage type change performance, so a code from another brand may not match directly.
