SKF BA series thrust ball bearings are components designed to support predominantly axial loads in one direction. They are used in applications requiring controlled thrust and low friction, such as lifting mechanisms, clutches and positioning systems. At MR Accesorios Industriales we carry this line as an official brand, backed by more than 80 years in the Argentine industrial market.
The BA series designation consists of the letters BA followed by a number indicating the size. For example, BA 4, BA 5, BA 6, BA 7, BA 8 and BA 9 correspond to different diameters and capacities. The number is not a direct diameter code; it identifies each size within the series. To select the correct bearing, it is essential to know the housing and shaft dimensions, as well as the axial load it will have to support.
These bearings are used in industries such as metallurgy, food, textile and agricultural machinery. In Argentina, they are commonly found in presses, lathes, bucket elevators and transmission equipment. Their ability to support axial loads in a single direction makes them suitable for applications where the thrust is constant and in one direction only, such as feed screws or rotary tables.
For a correct selection, take into account the direction of the axial load, the rotation speed and the environmental conditions. It is important to verify the axial clearance and the alignment between the shaft and the housing, since these bearings do not compensate for angular misalignment. Proper lubrication, whether grease or oil, extends service life. Sealing will depend on the contamination present; in dirty environments, additional protection is recommended.
As for equivalents, SKF thrust ball bearings can be interchanged with those of other brands that follow the same standardized dimensions. However, always verify tolerances and cage type, as they may vary between manufacturers. We do not invent part numbers or dimensions: if you need an equivalent, ask us with the original part number and we will help you find the right option.
