For equipment that needs a reliable barrier between rotating and stationary parts, the DBH 9976 radial shaft seal is a lip seal sized for a 21 mm shaft and a 61 mm housing bore. Its 7.00/14.00 mm height follows the A 361 profile, which has an asymmetrical lip section. This seal helps keep oil or grease in and contaminants out of gearboxes, pumps and other power transmission assemblies. MR Industrial Accessories supplies this brand and can help you verify the dimensions before you request a quote.

The DBH 9976 is identified by code 9976. Its key dimensions are shaft diameter 21 mm, housing bore 61 mm and overall height 7.00/14.00 mm. The A 361 design indicates a sealing lip combined with a body of variable height, intended for housings with a shoulder or for covering a mounting range. The lip contacts the rotating shaft while the outer surface seats in the housing to create the seal.

Seals of this size are common in gearboxes, electric motors, centrifugal pumps, rollers and power transmission equipment. They serve two purposes: retaining lubricant within the assembly and blocking the ingress of dust, water or particles. Because it is a wear component, check it whenever you notice leaks or unusual bearing noise.

When selecting a replacement, confirm that the shaft and housing diameters match the stated values. The lip should have a slight interference fit on the shaft, but not so much that it generates excess heat. During installation, lubricate the lip, avoid striking it, and use a tube or press that applies force to the outer face. If the shaft shows wear or grooves, consider a repair sleeve or an alternative size.

If you need an equivalent, send us code 9976 along with your shaft and housing dimensions. A photo of the old part or the assembly drawing also helps. With that information we can look for an option in the DBH line. Keep in mind that manufacturer designations may vary between series, so technical confirmation is the step before any quote.
