The DBH 1171 seal is a radial shaft seal of A 378 design that is mounted in housings of 110 mm diameter and 12 mm height. Its function is to retain the lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and bushings. It is a common replacement part in industrial equipment that operates with rotating shafts and requires 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 the metal body, but it does not replace the inquiry of the exact shaft size that your equipment needs.

Seals of this type are used in gearboxes, pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a fixed housing. They also appear in old or European-origin machines, where code 1171 and A 378 design allow locating the spare part without depending on the original size. If the seal is hardened, deformed or has lip loss, it is advisable to replace it before the lubricant escapes and affects nearby bearings or gears.

To properly select a radial shaft seal, three things must be confirmed: the shaft diameter, the housing diameter and the height. Also, check the condition of the shaft surface, because a scratched or worn track makes any new seal leak. During assembly, lubricate the lip with the same grease or oil of the equipment, seat the seal well perpendicular and tap with a tube of adequate diameter, never with a screwdriver. If the housing has burrs or the shaft has a shoulder, correct it before placing the part.

If code 1171 does not match the size you need, an equivalent can be searched within the same category of radial shaft seals. For that it is advisable to send the shaft diameter, housing diameter and actual height, plus a photo of the old seal and the housing.
