The SKF double row angular contact bearing is a component designed to support combined radial and axial loads in both directions. Its two-row ball construction delivers high performance in applications requiring rigidity and precision. It is a reliable solution for industrial machinery operating at moderate and high speeds, and it is part of the broad range of bearings that MR Accesorios Industriales supplies as a brand.
The designation of this series is interpreted from the basic code and the suffixes. For example, in 3318 DMA/VB188, the number 3318 indicates the size and dimension series, while DMA and VB188 are suffixes that identify construction variants, such as cage design, internal clearance or special treatments. These suffixes may vary by manufacturer and application, so it is essential to verify the complete part number when making a selection.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, food processing, cement and mining. They are common in applications such as centrifugal pumps, compressors, gearboxes, industrial fans and machine tools. Their ability to support axial loads in both directions makes them ideal for equipment requiring high rigidity and rotational precision.
To correctly select a double row angular contact bearing, take into account the radial and axial load it must support, the operating speed and the environmental conditions. It is important to verify adequate sealing to prevent contamination and lubricant loss. During mounting, ensure precise alignment and correct fit, since these bearings are sensitive to mounting errors. Lubrication must be suitable for the application and the internal clearance must be selected according to the equipment tolerances.
Regarding equivalents and interchangeability, double row angular contact bearings can be found under different brands with similar designations, but they are not necessarily interchangeable without verifying dimensions and capacities. It is always advisable to consult a specialist before replacing one bearing with another of a different brand. At MR Accesorios Industriales we can advise you to find the best option for your application.
