Decoding NTN 51410A
- 514Series
- Thrust ball bearings, 514 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- ASuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
51410 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 51410A measures 50 mm across the bore and 110 mm across the outside diameter; its height is 43 mm (50 x 110 x 43 mm).

The NTN series A thrust ball bearing is built to handle axial loads in a single direction. It suits equipment where thrust is the primary force, such as gearboxes, pumps, and other industrial machinery. The ball-and-flat-ring construction allows smooth rotation and contributes to dependable operation.
In the NTN series A designation, the main number indicates size and load capacity, while the trailing A identifies a construction variant. For instance, 51410A is a single-row thrust ball bearing with dimensions that follow international standards. This coding lets you quickly recognize the type and key characteristics.
These bearings appear in food processing, petrochemical, steel, and mining operations. Common uses include rotary tables, vertical pump shafts, speed reducers, and lifting equipment. Because they support axial loads, they are a good fit for mechanisms where thrust dominates, helping maintain stable operation under demanding conditions.
When selecting a thrust ball bearing, consider the axial load's magnitude and direction, rotation speed, and environmental conditions. Proper installation requires precise alignment of the rings and adequate lubrication, which may be grease or oil. Check axial clearance and ensure correct fastening on the shaft and housing to avoid premature wear.
Thrust ball bearings from different manufacturers often share standardized dimensions, so replacement is possible if tolerances and load capacities match. Still, internal design and materials can vary, so it is wise to confirm compatibility with a specialist. MR can advise on the best option for your equipment.

Frequently asked questions
- NTN 51410A bearing: what are its dimensions?
- NTN 51410A measures 50 mm across the bore and 110 mm across the outside diameter; its height is 43 mm (50 x 110 x 43 mm). Those are the boundary dimensions standardized in ISO 104 for basic designation 51410.
- What does the letter A indicate in the NTN thrust ball bearing designation?
- The final A denotes a construction variant within the series, which may involve cage design, tolerances, or heat treatment. For details on a specific code like 51410A, contact us via WhatsApp.
- How do I select the right thrust ball bearing for my application?
- Evaluate the axial load, speed, temperature, and environment. Also verify mounting dimensions and lubrication type. MR can help you choose the correct bearing.
- Can I replace a thrust ball bearing from another brand with an NTN one?
- Often yes, if dimensions and load capacities are equivalent. Check interchangeability carefully. Send us the original part code and we will indicate a compatible NTN option.
