The DBH 9894 radial shaft seal is a single-lip seal that mounts on the shaft and inside the housing to retain lubricant and block the entry of dust, water or particles. Its A 348 design and dimensions of 56.5 mm shaft, 79.45 mm housing and 15.00/17.50 mm height place it in power transmission applications and rotating equipment where axial space is limited. It is a wear part: it is replaced when oil leakage or dirt ingress appears.

This item is a DBH radial shaft seal identified with the designation 9894. Its dimensions are 56.5 mm shaft diameter, 79.45 mm housing diameter and a height of 15.00/17.50 mm, with A 348 design. That double height indicates that the seal can be seated in cavities of different depths without losing contact. The lip runs on the rotating shaft and the outer case remains fixed in the housing, creating the seal.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is continuous rotation and the presence of oil or grease. It also appears in applications exposed to dust or water, where the seal serves a dual purpose: it retains lubricant inward and slows the ingress of contaminants toward the bearings or bushings. It is commonly found in industrial equipment maintenance and in the replacement of machines in service.

To select it, verify that the shaft and housing diameters match the values on the product page. The 15.00/17.50 mm height allows it to be mounted in cavities between those two dimensions. Check the condition of the shaft surface: scratches or wear in the lip contact area accelerate leakage. During installation, lubricate the lip and use a tool that does not damage it. If the shaft has play or eccentricity, consider an alternative with a reinforced lip.
