How to read NTN 51410A
- 514Series
- Thrust ball bearings, 514 series. For the same bore, each series has a different outside diameter and width.
- 10Bore
- 50 mm bore: 10 × 5.
- ASuffix
- NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).
51410 is the standard (ISO) basic designation: it defines the type, the series and the bore.

The NTN series A thrust ball bearing is a component designed to support predominantly axial loads in one direction. It is used in applications requiring high thrust capacity and precise alignment, such as gearboxes, pumps and industrial equipment. Its design with balls and flat rings allows smooth and efficient rotation, contributing to the reliability and durability of machinery. MR Accesorios Industriales sells this series for the Argentine market.
The designation of the A series in NTN thrust ball bearings is interpreted as follows: the main number indicates the size and load capacity, while the final letter A indicates a specific construction variant within the series. For example, the code 51410A corresponds to a single row thrust ball bearing, with dimensions standardized according to international standards. This nomenclature allows you to quickly identify the type and main characteristics of the product.
These bearings are used in various industries in Argentina, such as food, petrochemical, steel and mining. They are found in applications such as rotary tables, vertical pump shafts, speed reducers and lifting equipment. Their ability to support axial loads makes them ideal for mechanisms where thrust is the main load, ensuring stable and prolonged operation under demanding conditions.
To correctly select a thrust ball bearing, it is essential to consider the magnitude and direction of the axial load, as well as the rotation speed and environmental conditions. Installation requires precise alignment of the rings and adequate lubrication, which can be grease or oil depending on the application. It is important to check the axial clearance and ensure correct fastening on the shaft and housing to avoid premature wear.
Regarding equivalences and interchangeability, thrust ball bearings from different manufacturers may have standardized dimensions that allow replacement, provided that tolerances and load capacities are respected. However, it is recommended to consult specialists to validate compatibility, as there may be variations in internal design and materials. MR Accesorios Industriales can advise you on the best option for your equipment.
