The NTN 79 LLB series angular contact ball bearing is a precision part designed to support combined radial and axial loads in a single direction. Its contact angle design makes it suitable for applications requiring high rigidity and rotational accuracy, such as machine tool spindles or measuring equipment. MR Accesorios Industriales sells this series as part of its precision bearing line, with more than 80 years of experience in the Argentine industrial market.
The 79 LLB series designation reads as follows: the base number (for example, 7000, 7001, 7002) indicates the bearing size according to the bore diameter, where the last two digits correspond to the diameter in millimeters multiplied by 5. The letters CD indicate an angular contact design with a 15° angle and a polyamide cage, while LLB indicates the type of sealing or protection. Thus, a 7000CDLLB is an angular contact bearing of the 70 series, with the CD and LLB characteristics. This nomenclature makes it possible to quickly identify the key specifications.
These bearings are used in applications that demand high precision and combined load capacity. In Argentine industry, they are common in machine tool spindles, milling machine heads, measuring equipment, industrial robots and positioning systems. They are also used in high-pressure pumps and compressors where axial rigidity is required. Their ability to work at high speeds makes them suitable for precision electric motors and grinding machine spindles.
To correctly select an angular contact bearing, you must consider the direction of the axial load, the internal clearance, the lubrication and the mounting. These bearings are generally mounted in pairs, with preload adjusted to eliminate axial clearance and increase rigidity. The LLB seal protects against contamination and retains the lubricant. Alignment between the shaft and the housing is critical; any misalignment reduces service life. It is recommended to follow the manufacturer's instructions for mounting and lubrication.
As for equivalents and interchangeability, NTN angular contact bearings can be replaced by products from other brands that follow the same international nomenclature, such as SKF, FAG or NSK, as long as the dimensions and the load and speed specifications match. It is important to verify the contact angle and the cage type, since they can vary between manufacturers. For a safe substitution, it is advisable to consult a specialist and provide the complete part number of the original part.

Frequently Asked Questions
- What does the 79 LLB designation mean in these bearings?
- The number 79 indicates the dimensional series, where the last digit relates to the bore diameter. LLB refers to the type of sealing or protection. The letters CD, present in the examples, indicate an angular contact design with a 15° angle and a polyamide cage.
- Can these bearings be mounted in pairs?
- Yes, angular contact bearings such as those in the 79 LLB series are usually mounted in pairs, face-to-face or matched, to support axial loads in both directions and increase the rigidity of the assembly. Mounting must be done with the appropriate preload for the application.
- How do I request a quote for an NTN 79 LLB bearing?
- Write to us on WhatsApp with the complete part number of the bearing you need, for example 7000CDLLB. At MR Accesorios Industriales we will quote it shortly. If you have doubts about the nomenclature, we can also help you identify it.
