The NTN series A angular contact ball bearing is a component designed to support combined radial and axial loads in a single direction. Its design with oblique contact raceways allows precise operation in applications requiring high rigidity and speed. MR Accesorios Industriales sells this series.
The designation of the NTN series A is interpreted by its basic code and suffixes. The code KXA identifies a single row angular contact bearing. Additional suffixes, such as those appearing in the catalog, indicate variants in the contact angle, internal clearance or cage type. For example, a suffix may indicate a polyamide or brass cage, or a larger axial clearance. Knowing these codes allows you to select the exact variant for each application.
These bearings are used in centrifugal pumps, compressors, gearboxes, machine tool spindles and transmission equipment. In Argentine industry, they are common in the food, petrochemical, metallurgical sectors and in agricultural machinery manufacturing. Their ability to support axial loads in one direction makes them ideal for paired arrangements, where two bearings counteract opposing forces.
To select correctly, take into account the direction of the axial load, the rotation speed and the environmental conditions. The sealing can be open, with shields or with seals, depending on contamination and the need for lubricant retention. The internal clearance should be chosen according to the working temperature and the mounting fit. Lubrication can be with grease or oil, and alignment between housings is critical to avoid parasitic loads.
Regarding equivalences, angular contact bearings from different brands can be interchanged if the main dimensions, contact angle and clearance match. It is essential to verify the complete code and the tolerances. MR Accesorios Industriales can advise you on interchangeability and quote the exact reference you need.

Frequently Asked Questions
- What does the series A mean in NTN bearings?
- The series A identifies single row angular contact ball bearings. The basic code and the suffixes indicate characteristics such as the contact angle, the internal clearance and the cage type. Knowing the complete designation allows you to select the appropriate variant for each application.
- How do I choose between an open and a sealed bearing?
- The choice depends on the environment: if there is dust or moisture, a sealing with shields or seals is advisable; if continuous lubrication is required, it can be open. Speed and temperature also influence the choice. At MR we advise you according to your equipment and working conditions.
- Can I replace a bearing from another brand with an NTN one?
- Yes, as long as the main dimensions, the contact angle and the internal clearance match. It is important to verify the complete code and the tolerances. MR Accesorios Industriales helps you validate the equivalence and quotes you the NTN reference you need.
