An NSK double row angular contact ball bearing carries radial and axial loads in both directions at once. Two rows of balls give the bearing the stiffness to handle tilting moments, which is why it turns up in spindles, pumps and gearboxes where precision matters. MR Industrial Accessories LLC supplies this NSK line to customers in the United States and Latin America, quoting by part number through WhatsApp or email.

Reading the code tells you most of what you need. In 5200DDU, the 5200 series points to a double row bearing in the 10 mm diameter series, while DDU means contact rubber seals on both sides, keeping contamination out and lubricant in. Suffixes can also flag synthetic cages, internal clearance or special tolerances, so it pays to send the full part number rather than a shortened version.

Typical service includes machine tool spindles, centrifugal pumps, gearboxes, compressors and transmission systems, wherever radial and axial loads arrive together with a moment. The double row construction holds alignment and limits clearance under load, which suits packaging lines, agricultural machinery and process plant equipment.

Selection comes down to load size and direction, running speed and the surrounding environment. DDU sealing fits dusty or damp locations because particles stay outside the bearing. Factory grease normally covers the service life, though tougher duty may call for relubrication. Mounting needs accurate alignment between shaft and housing plus the correct fit, so internal clearance is not disturbed.

Interchange is a matter of dimensions and load capacity, not matching part numbers across brands. Bring an unidentified bearing or a number from another maker and the functional characteristics can be compared to find a replacement. If you need this NSK bearing or want to check another reference, send the part number or main dimensions on WhatsApp or by email and the team will reply promptly, suggesting an equivalent where useful.
