The DBH 9976 radial shaft seal is a lip seal that mounts on a 21 mm shaft and seals against a 61 mm housing. Its height of 7.00/14.00 mm corresponds to an A 361 design, with an asymmetrical-section lip that improves contact and lubricant retention. It is used to contain oil or grease and exclude dust and water in gearboxes, pumps and power transmission equipment.

This item is a radial shaft seal from the DBH line, identified with code 9976. Its dimensions are shaft (d) 21 mm, housing (D) 61 mm and height (h) 7.00/14.00 mm. The A 361 design defines a profile with a sealing lip and a variable-height body, intended for housings with a shoulder or to cover a mounting range. The lip runs on the rotating shaft and the outer face seats in the housing, creating the tight seal.

Typical applications for a seal of this size include gearboxes, electric motors, centrifugal pumps, rollers and power transmission equipment. In all cases it performs two functions: retaining the lubricant inside the assembly and preventing the entry of contaminants such as dust, water or particles. It is a wear part, so it should be inspected when leaks or bearing noise appear.

To select correctly, verify that the shaft and housing diameters match the values indicated. The lip should have a slight interference fit on the shaft, without excess that generates heat. During installation, lubricate the lip, avoid striking it and use a tube or press that bears on the outer face. If the shaft shows wear or grooves, consider a repair sleeve or an alternative size.

If you need an equivalent or a nearby size, send us code 9976 together with the shaft and housing dimensions. You can also send a photo of the old part or the assembly drawing. With that data we look for the option in the DBH line or a compatible alternative. Keep in mind that the manufacturer's designation may vary between series, so technical confirmation is the step before any quote.
