Angular contact ball bearings

Angular contact ball bearings accommodate radial and axial loads in a single direction. Their design with raceways and balls in oblique contact provides greater axial capacity than a deep groove ball bearing and requires mounting with preload or paired arrangements. To select the right one, you must define the combined load, speed, required rigidity and type of fit; in spindles and precision equipment, series with fine dimensional and running tolerances are used, while standard versions suffice for general applications.

In the catalog you will find versions that meet different needs. The 70 series (for example 7006 CD/HCP4ADGA) are single-row, high-precision bearings with ceramic balls and universally matchable pairs; the suffix CD indicates a 15° contact angle and HCP4A refers to hybrid balls and precision class P4A. The S70 series (S7003 ACDGA/P4A) is similar but with a design optimized for high speeds. The QJ (QJ 307 N2MA/C2L) are four-point contact bearings, suitable for axial loads in both directions and moment loads. The BSD (BSD 3062 CGB) and BSA (BSA 204 CGB) are spindle units with single-row angular contact, factory preloaded and ready to mount in machining assemblies.

Typical applications include machine tool spindles, milling heads, high-speed electric motor shafts, pumps, compressors and gearboxes where axial rigidity and running accuracy are required. They are also used in measuring equipment and test benches that require repeatability.

To request a quote, we need the complete bearing part number (for example 7006 CD/HCP4ADGA or BSD 3062 CGB), the brand and, if you do not have the part number, the main dimensions: bore diameter, outside diameter and width, along with the bearing type (single row, double row, four-point) and the precision class. If you have an equivalent from another manufacturer, send it and we will verify it.
