The DBH 9986 oil seal is a single-lip radial shaft seal that mounts on a rotating shaft to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings and gears must be protected. Its A 094 design and its 14.0/16 mm height make it suitable for housings with a reinforced-section seal. MR Accesorios Industriales carries this brand with more than 80 years of experience in the field.

The DBH 9986 is a lip-type radial shaft seal, identified by the designation 9986 and the A 094 design. Its dimensions are: shaft diameter 108 mm, housing diameter 154 mm and height 14.0/16 mm. The double height indicates that the outer lip has a shoulder or that the seal allows two mounting positions depending on the housing. The sealing lip runs on the shaft and the outer diameter fits by interference in the housing. It is a direct replacement component, not a split seal.

This type of seal is used in equipment with large-diameter shafts: speed reducers, mills, mixers, centrifugal pumps, industrial fans and continuous-process machines. It also appears in heavy-duty conveyor rollers and in gearboxes where oil must be contained. The main function is to prevent lubricant leaks and, at the same time, to stop contaminants from entering that accelerate wear on bearings and gears. In dusty or humid environments, the seal is the first barrier of protection.

To select the correct seal, verify that the shaft and housing diameters match the values on the product page. The 14.0/16 mm height must fit into the cavity without deforming; if the housing has a shoulder, respect the lip orientation. During mounting, lubricate the lip with the same grease or oil used in the equipment, avoid striking it and use a support tube to seat it evenly. A damaged lip or a shaft with splines or scratches causes leaks even if the seal is new. Also check the shaft's axial play.

If you need a nearby size or an equivalent, send us code 9986 along with the shaft, housing and height dimensions. You can also send a photo of the old seal or the housing drawing. With that data we look for alternatives within the same brand or other lines we carry. If the A 094 design is not available, we evaluate a seal with the same section and a different lip, as long as the mounting dimensions are maintained. The idea is that you don't stop the equipment for a seal.
