The NTN 5S-79 LLB series angular contact ball bearing is a precision component designed to support combined radial and axial loads in a single direction. Its high-speed design and LLB sealing construction make it ideal for machine tool spindles, high-frequency motors and equipment requiring rigidity and accuracy. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.

The designation of the 5S-79 LLB series is interpreted as follows: the 5S prefix indicates the presence of low-friction seals; the number 79 defines the extra-thin section dimensional series; and the LLB suffix corresponds to the type of non-metallic sealing. Examples such as 5S-7000ADLLB, 5S-7001ADLLB and 5S-7002ADLLB show how the size varies according to the numeric code. The contact angle of 15° or 25° (depending on variant) allows high speeds with good axial load capacity.

These bearings are used in spindles of milling machines, grinding machines and machining centers, where precision and speed are critical. They are also used in high-frequency electric motors, measuring instruments and optical equipment. In Argentina, the automotive, aeronautical and machine tool sectors demand this series for its reliability. MR Accesorios Industriales supplies them to workshops and industrial plants in Buenos Aires and the rest of the country.

To select the correct bearing, take into account the axial and radial load, the rotation speed and the internal clearance. The LLB seal protects against contaminants and retains lubricant, but compatibility with the environment must be verified. Mounting must ensure precise alignment and adequate preload, since these bearings are usually mounted in pairs. Lubrication with high-speed grease or oil is essential to achieve the expected service life.

NTN 5S-79 LLB series angular contact bearings are interchangeable with other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK, as long as tolerances and contact angle are respected. When replacing, verify the complete code and mounting conditions. If you have doubts, our technical team can advise you.
