The FAG MP series thrust ball bearing is a component designed to support predominantly axial loads in one direction. Its design with balls and flat rings suits applications requiring high load capacity and rigidity. MR Accesorios Industriales carries this series as part of its bearing line.
The MP series designation consists of a five-digit number indicating size and load capacity, followed by the MP suffix. For example, 51130-MP, 51132-MP and 51134-MP correspond to single-direction thrust ball bearings. The MP suffix indicates a machined brass cage, suitable for demanding applications. This nomenclature allows quick identification of size and main characteristics.
These bearings are used in applications where axial loads are predominant, such as gearboxes, pumps, compressors, machine tools and lifting equipment. In Argentine industry, they are common in the metalworking, food and petrochemical sectors. Their ability to support unidirectional loads makes them ideal for assemblies requiring precision and axial rigidity.
To select the right thrust ball bearing, take into account the axial load, rotational speed and environmental conditions. It is essential to verify ring alignment and ensure proper lubrication, whether with grease or oil. Mounting must be done with appropriate tools to avoid damaging the raceways. The MP brass cage offers good strength and heat dissipation.
Regarding equivalences, thrust ball bearings from other brands may have similar designations, but it is important to verify dimensions and tolerances. Interchangeability between brands is not always direct; consulting a specialist is recommended. MR Accesorios Industriales can advise you to find the best option for your application.

Frequently Asked Questions
- What are the dimensions of the FAG 51144-MP bearing?
- The FAG 51144-MP bearing has a 220 mm bore, a 270 mm outside diameter and a 37 mm height (220 x 270 x 37 mm). These are the standardised boundary dimensions (ISO 104) of the basic designation 51144.
- What does the MP suffix mean in the designation?
- The MP suffix indicates that the bearing incorporates a machined brass cage, giving it greater strength and capacity for high-load and high-speed applications. It is a quality hallmark of the series.
- How do I choose the correct thrust bearing size?
- You should consider the axial load it will support, the shaft diameter and the housing dimensions. With that data, we can advise you to select the right part number within the MP series.
- Are FAG MP series thrust ball bearings interchangeable with other brands?
- Dimensional equivalents may exist, but interchangeability is not automatic. It is advisable to verify the tolerances and characteristics of each manufacturer. Consult us with the part number and we will help you find the right option.
