Angular contact ball bearings in NTN's C series handle radial and axial forces simultaneously. The offset raceway design creates an oblique ball-to-ring contact angle, which provides greater axial capacity than a standard deep groove ball bearing. These bearings suit applications requiring precise guidance and thrust support in one direction.

Reading the part number is straightforward. The digits indicate the bearing size, while the final letter C denotes a 15° contact angle. In codes such as 7200C, 7201C, or 7206C, the numeric portion defines the principal dimensions and the C confirms the contact geometry. Larger numbers correspond to larger bearings. This consistent naming convention lets you identify the contact angle directly from the code.

Typical uses include machine tool spindles, centrifugal pumps, compressors, gearboxes, and transmission equipment where radial and axial loads occur together. They also appear in precision applications demanding rigidity and low friction, such as milling heads or electric motor shafts. Because they are angular contact bearings, they are often chosen for assemblies where the bearing itself must absorb axial thrust rather than other components.

Selecting the right bearing involves the magnitude and direction of the load, the rotational speed, and the mounting arrangement. These bearings are commonly installed in pairs, either face-to-face or back-to-back, to accommodate axial loads in both directions. Proper lubrication for the operating conditions and accurate alignment between shaft and housing are essential to prevent parasitic stresses. Sealing or shielding options depend on the environment; protected variants are advisable where dust or moisture is present.

When replacing a bearing from another manufacturer, interchangeability relies on standardized dimensions and contact angle. An equivalent code may match in size, but always check the letter defining the angle and the cage type, as these influence dynamic performance. Providing the complete code and housing dimensions is the best approach; MR Industrial Accessories will identify a compatible alternative or quote the exact code you need.

MR Industrial Accessories supplies NTN bearings. If you have the bearing code or the shaft and housing dimensions, send the details via WhatsApp or email and we will quote promptly. We can also advise on mounting and lubrication for your application.
