SKF thrust ball bearings are components designed to withstand predominantly axial loads in one direction. They consist of a shaft washer, a housing washer and a ball cage. They are used in applications requiring high axial rigidity and precision, such as machine tool spindles, lathe faceplates and lifting mechanisms. MR Accesorios Industriales sells this line.
The designation of SKF thrust ball bearings follows a numeric scheme that identifies dimensions and variants. For example, the 51100 series corresponds to single-direction bearings with a 10 mm shaft diameter, while other series indicate higher-capacity designs. Suffixes may indicate steel, brass or polyamide cages, and variants with spherical washers to compensate for misalignment. Knowing these codes facilitates correct selection according to the application.
These bearings are used in industries such as metalworking, food and petrochemical. In Argentina, they are common in milling machine spindles, rotary tables, vertical centrifugal pumps and lifting equipment. They are also used in clutches and steering mechanisms. Their ability to withstand axial loads makes them ideal for applications where axial space is limited and high rotational precision is required.
To select a thrust ball bearing, take into account the axial load it must withstand, the rotational speed and environmental conditions. It is essential to verify alignment between the washers, since these bearings do not compensate for angular misalignment. Proper lubrication, whether grease or oil, extends service life. Mounting must be done with tools that do not damage the raceways, and it is recommended to follow the manufacturer's instructions for axial clearance.
Regarding equivalences, SKF thrust ball bearings can be interchanged with those from other brands that follow the same standardized dimensions. However, it is important to verify tolerances and cage type, as they can affect performance. MR Accesorios Industriales offers advice to find the best option according to your specific needs, without compromising quality or compatibility.

Frequently Asked Questions
- What are the dimensions of the SKF 51305 bearing?
- The SKF 51305 bearing has a 25 mm bore, a 52 mm outside diameter and a 18 mm height (25 x 52 x 18 mm). These are the standardised boundary dimensions (ISO 104) of the basic designation 51305.
- What is the difference between a thrust ball bearing and a radial one?
- The thrust ball bearing supports loads in the axial direction, while the radial one supports them perpendicular to the shaft. They are not interchangeable in applications with significant combined loads.
- How is a thrust ball bearing mounted?
- It is mounted with the shaft washer on the shaft and the housing washer in the housing, ensuring precise alignment. It is recommended to use suitable tools and follow the manufacturer's instructions.
- What lubrication do you recommend for these bearings?
- It depends on speed and temperature. For high speeds, oil; for general applications, good quality grease. Contact us on WhatsApp for advice according to your case.
