How to read NTN 51101
- 511Series
- Thrust ball bearings, 511 series. For the same bore, each series has a different outside diameter and width.
- 01Bore
- 12 mm bore: code 01 stands for 12 mm by standard.
51101 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The NTN 51101 bearing has a 12 mm bore, a 26 mm outside diameter and a 9 mm height (12 x 26 x 9 mm).

The NTN thrust ball bearing is a component designed to withstand predominantly axial loads in one direction. It consists of two washers, one shaft washer and one housing washer, and a row of balls that rotates between them. It is used in applications where the main load is vertical, such as conveyor belts, mixers, centrifugal pumps and lifting equipment. MR Accesorios Industriales sells these products and advises you on choosing the correct part number.
The designation of NTN thrust ball bearings is based on the series indicated by the part number, which defines the main dimensions. The following numbers indicate the bore diameter: for example, 51100 corresponds to a 10 mm bore, 51101 to 12 mm, 51102 to 15 mm, and so on, depending on the series. In part numbers with a slash, such as 511/500 or 511/530, the number after the slash directly indicates the bore diameter in millimeters, depending on the series. This nomenclature allows you to quickly identify the shaft size where the bearing will be mounted.
In Argentine industry, NTN thrust ball bearings are used in equipment where axial loads are significant and radial loads are minimal. They are found in mining conveyor belts, industrial mixers, vertical centrifugal pumps, lifting winches and machine tools. They are also present in the food sector, in process equipment, and in the plastics industry, in extruders and blow molding machines. Their ability to withstand thrust in a single direction makes them suitable for these applications.
To select a thrust ball bearing, take into account the axial load it must withstand, the rotation speed and the available space. It is essential to verify alignment between the shaft and the housing, since these bearings do not compensate for angular misalignment. Lubrication can be with grease or oil, depending on the application and speed. Sealing will depend on the environment: in the presence of dust or moisture, additional protection is recommended. Assembly must be carried out with suitable tools to avoid damaging the washers.
There are equivalences between brands for thrust ball bearings: an NTN 51100 part number may correspond to similar designations from other brands, such as SKF, FAG or NSK, as long as they share dimensions and load capacity. If you have a part number from another brand, we can identify the NTN equivalent. We can also quote the exact size you need. Write to us on WhatsApp with the part number or dimensions and we will quote it shortly.

Frequently Asked Questions
- What are the dimensions of the NTN 51101 bearing?
- The NTN 51101 bearing has a 12 mm bore, a 26 mm outside diameter and a 9 mm height (12 x 26 x 9 mm). These are the standardised boundary dimensions (ISO 104) of the basic designation 51101.
- What does the designation 51100 mean in an NTN thrust bearing?
- The 51100 part number indicates a thrust ball bearing of the 511 series with a bore diameter of 10 mm, depending on the series. The last two digits correspond to the shaft diameter in millimeters. For other sizes, such as 51101 or 51102, the bore is 12 mm and 15 mm respectively.
- How do I choose the right thrust bearing for my application?
- To choose correctly, consider the axial load, the rotation speed and the mounting space. Verify that the shaft and housing are aligned. If there is dust or moisture, evaluate additional protection. With this data, we can quote the NTN part number that best suits you.
- Do you have equivalents from other brands for NTN thrust bearings?
- Yes, we can identify the NTN equivalent from a part number from another brand, such as SKF, FAG or NSK, as long as they share dimensions and load capacity. Write to us on WhatsApp with the original part number and we will quote the corresponding option shortly.
