The KRA series designation is interpreted from its letters and numbers. For example, KRA020, KRA025 and KRA030 indicate different sizes within the A series. The numeric suffix indicates the bearing bore diameter, while the letters KRA identify the series and the type of construction. This nomenclature allows you to quickly select the right bearing according to the required dimensions.

These bearings are used in industries such as food, textile, chemical and packaging, as well as in power transmission equipment, pumps, fans and conveyors. In Argentina, they are common in production lines that require high speed and low maintenance. Their ability to withstand combined loads makes them suitable for applications where precision and durability are critical.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing and lubrication are key: choose the appropriate seal type to prevent contamination and ensure a long service life. During mounting, verify alignment and internal clearance to avoid unnecessary stress. Lubrication must be the one recommended by the manufacturer for each application.

As for equivalences, deep groove ball bearings from different brands can be interchanged if the dimensions and tolerances match. Always verify the technical specifications before replacing one bearing with another from a different brand. If you have doubts, consult us with the original part number and we will advise you.
