SKF angular contact bearings are components designed to support simultaneous radial and axial loads. Their design with oblique contact raceways enables superior performance in applications requiring high precision and rigidity. At MR Accesorios Industriales we supply this line to meet the needs of Argentine industry, offering technical advice to select the right bearing for each application.
The designation of these bearings combines letters and numbers that indicate key characteristics. For example, in 71903 ACE/HCP4ADT, the numeric prefix identifies the series and size. The suffix ACE indicates a high-capacity angular contact design. HCP4 indicates a phenolic textile cage and dimensional precision. ADT specifies a universal set of two bearings with light preload. Knowing these codes makes correct selection easier.
These bearings are used in machine tool spindles, high-pressure pumps, compressors, electric motors and transmission equipment. In Argentina, they are common in the automotive, metalworking and food industries, where combined loads must be supported with high speed and precision. Their ability to work under demanding conditions makes them ideal for critical applications.
To select the right bearing, consider the magnitude and direction of the loads, the operating speed and the environmental conditions. Sealing and lubrication are crucial: choose the right lubricant and ensure a protective film. Precise alignment during mounting prevents undue stresses. In ADT sets, respect the specified preload for optimal performance. Careful mounting extends service life.
SKF angular contact bearings can be interchanged with those from other recognized brands, provided dimensions and load capacities match. Verify tolerances and internal clearance to ensure compatibility. At MR Accesorios Industriales we have the experience to advise you on equivalents and alternatives available on the market.

Frequently Asked Questions
- What does the ADT suffix mean on an SKF bearing?
- The ADT suffix indicates that it is a universal set of two angular contact bearings, mounted in tandem, with a predefined light preload. This facilitates installation and ensures optimal performance in applications requiring high rigidity and precision.
- How do I choose between an angular contact bearing and a radial one?
- Choose angular contact when the axial load is significant or combined with radial. Radial bearings mainly support radial loads. Consider the magnitude of the loads, the speed and the required precision. Our team can advise you according to your specific application.
- What care should I take when mounting an angular contact bearing?
- Ensure precise alignment, use the right tools and respect the preload if it is a set. Lubricate correctly and avoid impacts that damage the raceways. Careful mounting extends the bearing's service life and maintains performance.
