The DBH 1171 oil seal is a radial seal with A 378 design that mounts in housings of 110 mm diameter and 12 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that could damage bearings and bushings. It is a common replacement part in industrial equipment operating with rotating shafts and requiring reliable sealing under continuous working conditions.

This item is a DBH radial shaft seal with designation 1171 and A 378 design. According to the data sheet, it is installed in a housing of 110 mm outer diameter and has 12 mm height. The A 378 design defines the geometry of the lip and metal body, but does not replace the need to consult the exact shaft size required by your equipment.

Seals of this type are used in gear reducers, pumps, electric motors, rollers and transmission equipment where a shaft rotates within a fixed housing. They also appear in older or European-origin machines, where the code 1171 and A 378 design allow locating the spare part without relying on the original size. If the seal is hardened, deformed or has lost its lip, it should be replaced before lubricant escapes and affects nearby bearings or gears.

To properly select a radial shaft seal, three things must be confirmed: shaft diameter, housing diameter and height. Also check the condition of the shaft surface, because a scratched or worn track will cause any new seal to leak. During assembly, lubricate the lip with the same grease or oil used in the equipment, support the seal perpendicularly and tap with a tube of suitable diameter, never with a screwdriver. If the housing has burrs or the shaft has a step, correct it before installing the part.

If the code 1171 does not match the size you need, an equivalent or nearby size can be sought within the same category of radial shaft seals. For this, it is advisable to send the actual shaft diameter, housing diameter and height, plus a photo of the old seal and the housing. With this data, MR Accesorios Industriales compares against alternatives and proposes the closest option, without inventing sizes not confirmed by the manufacturer.
