When equipment needs to handle radial and axial forces simultaneously in both directions, the NTN SC series double row angular contact ball bearing is a common choice. Its two rows of balls and defined contact angle provide the rigidity and precision that industrial machinery, transmissions and other demanding applications require. MR Industrial Accessories supplies this series and offers the technical guidance to match the right part number to your setup.

Reading an SC series part number is straightforward: the digits indicate size, while the letters specify the series and closure. Take 5200SCZZ, 5201SCZZ and 5202SCZZ. The first four digits change with the bearing's dimensions, SC identifies the double row angular contact design, and ZZ means metal shields on both sides. Other suffixes may appear for different closure types. If any part of the code is unclear, forward the complete part number and we will quote it.

These bearings appear in food processing, metallurgy, textiles and plastics operations, often in pumps, compressors, fans, conveyors and machine tools. Their double row layout can replace two single row bearings in a tighter envelope, which simplifies equipment design. They are especially useful where loads come from two directions and alignment must be maintained.

Selection depends on the radial and axial loads, rotational speed and the surrounding environment. ZZ shielding keeps out dust and moisture, but for direct contact with liquids or vapors, consider other sealing options. During mounting, use the proper tools and avoid hitting the balls or raceways. Check shaft and housing alignment, and pay attention to lubrication and internal clearance, as these influence service life.

NTN SC series bearings can be interchanged with equivalents from other manufacturers that use the same dimensional nomenclature, such as SKF, FAG or NSK, provided the main dimensions and sealing type align. Always confirm the contact angle and load capacity, since these can differ between brands. Dimensions and technical data help identify a compatible alternative. At MR Industrial Accessories, we can assist in finding the right interchange.
