The DBH 9863 oil seal is a radial shaft seal with an A 321 design that is installed between a rotating shaft and a fixed housing to retain lubricant and exclude contaminants. Its dimensions are 54 mm shaft diameter, 64 mm housing diameter and a height of 9 to 24 mm. It is a wear part that should be replaced when oil leakage or dirt ingress appears. MR Accesorios Industriales supplies it as an official brand.
This item is a DBH 9863 radial shaft seal, identified by its numeric designation and by the A 321 design. It runs on a 54 mm diameter shaft and fits into a 64 mm diameter bore, with a height of 9.00/24.00 mm corresponding to the sealing lip and the outer structure. The A 321 design defines the geometry of the lip and the metal body, intended for applications where the seal must adapt to a cavity with a variable usable depth. The DBH brand is an official brand that MR supplies, so the replacement part is identified by its exact code.
Radial shaft seals such as the DBH 9863 are used in gearboxes, pumps, electric motors, transmission shafts and rotating equipment in general. Their function is twofold: to prevent lubricant from escaping to the outside and to stop dust, water or particles that accelerate wear on bearings and gears from entering. In industrial plants, factories and process equipment, this type of seal is a common consumable that is replaced during preventive maintenance or when a leak is detected.
To install a seal of this type, check that the shaft and housing are clean, free of burrs and deep marks. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly on the lip. The 9.00/24.00 mm height allows some tolerance in the housing depth, but it is advisable to confirm that the lip rests on a shaft surface in good condition. If the shaft shows wear, consider a nearby size or a repair sleeve.
If you need an equivalent or a different size, send us the complete seal code, the shaft, housing and height dimensions, and a photo or sample of the profile. With that data we can look for an alternative within the DBH line or from other brands we supply. We can also advise you if the A 321 design is not suitable for your application and a different type of lip or material is needed.

Frequently Asked Questions
- What are the dimensions of the DBH 9863 oil seal?
- The DBH 9863 oil seal has a 54 mm shaft diameter, a 64 mm housing diameter and a height of 9.00/24.00 mm. These dimensions correspond to the A 321 design and are the ones you need to verify before replacing the seal in your equipment.
- How do I know if the oil seal is worn?
- Typical signs are lubricant leakage around the shaft, dust or water ingress, and noise or vibration in the nearby bearing. If the lip is hardened, cut or deformed, the seal should be replaced with a new one of the same dimensions.
- Can I request an equivalent size to the DBH 9863?
- Yes. Send the code and the shaft, housing and height dimensions by WhatsApp, and we will look for an alternative within the DBH line or from other brands we supply. We can also evaluate a different design if your application requires it.
