SKF angular contact bearings handle radial and axial loads at the same time. Their raceways are positioned at an angle, which suits arrangements that call for precision and rigidity. MR Industrial Accessories LLC supplies this line to customers in the United States and Latin America, and can help you match a bearing to your application.
The part number carries most of the selection information. Take 71903 ACE/HCP4ADT: the digits give the series and size, ACE denotes the high-capacity angular contact execution, HCP4 refers to a phenolic textile cage and dimensional precision, and ADT identifies a universal set of two bearings with light preload. Reading these blocks before ordering reduces the chance of mounting the wrong arrangement.
Typical installations include machine tool spindles, high-pressure pumps, compressors, electric motors and transmission equipment. In these duties the bearing has to carry combined loads while running at speed and holding position. That is why they appear in automotive, metalworking and food processing plants, where a spindle or pump cannot lose accuracy.
Selection starts with load magnitude and direction, operating speed and the surrounding conditions. Lubrication and sealing matter just as much: use the correct lubricant and keep a protective film on the raceways. Alignment during mounting should be precise, and on ADT sets the specified preload must be respected. Care at this stage protects the bearing over its service life.
SKF angular contact bearings can be replaced with equivalents from other recognized brands when dimensions and load capacities correspond. Check tolerances and internal clearance before substituting. MR Industrial Accessories LLC can review the interchange and point you to the matching option.

Frequently asked questions
- What does the ADT suffix mean on an SKF bearing?
- It identifies a universal set of two angular contact bearings arranged in tandem with a defined light preload. This simplifies mounting and supports applications that need rigidity and precision.
- When should I use an angular contact bearing instead of a radial one?
- Use angular contact when axial load is significant or comes combined with radial load. Radial bearings are mainly for radial loads. Load size, speed and required precision should guide the decision, and our team can advise on your specific case.
- What should I watch during mounting?
- Keep alignment precise, use suitable tools and respect the preload on sets. Lubricate correctly and avoid impacts that could damage the raceways. Careful mounting helps the bearing hold its performance over time.
