The SKF double row angular contact bearing is built to handle combined radial and axial loads in both directions. With two rows of balls, it provides the rigidity and precision needed for industrial machinery running at moderate to high speeds. This bearing is part of the range that MR Industrial Accessories supplies to customers across the United States and Latin America.
The part number tells you a lot about the bearing. In 3318 DMA/VB188, the 3318 is the size and dimension series, while DMA and VB188 are suffixes for construction details such as cage design, internal clearance or special treatment. Suffixes can differ from one maker to another, so always confirm the full number when selecting a replacement.
These bearings show up in centrifugal pumps, compressors, gearboxes, industrial fans and machine tools, and in industries like metallurgy, food processing, cement and mining. Because they take axial load in both directions, they suit equipment where rigidity and rotational accuracy matter.
When choosing a double row angular contact bearing, look at the radial and axial loads, the operating speed and the environment. Check that sealing is adequate to keep contamination out and lubricant in. During mounting, alignment and fit must be precise, as these bearings are sensitive to installation errors. Lubrication should match the application, and internal clearance should be selected according to the equipment tolerances.
Equivalents from other brands may carry similar designations, but they are not always interchangeable without checking dimensions and capacities. It is best to speak with a specialist before swapping one brand for another. At MR Industrial Accessories we can help you find the right option for your application.
