The DBH 6758 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Due to its dimensions, 44.45 mm shaft, 68.22 mm housing and 15.87 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment working with medium-section shafts. MR Accesorios Industriales carries this official brand and helps you confirm the size before requesting a quote.

This item is a seal from the DBH line, identified with part number 6758 and Kx design. Its dimensions are d 44.45 mm, D 68.22 mm and h 15.87 mm. The Kx design corresponds to a seal with a sealing lip and metal reinforcement, intended for rotating shafts with a rigid housing. The series nomenclature does not include further variants under this part number: the size is the one shown on the product page and it is advisable to verify it against the drawing or the original part before replacing.

Typical applications for a seal of this size appear in gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment where a shaft rotates inside a housing. It is also used in rollers, mixers and continuous process machinery. In all cases it performs two functions: retaining the oil or grease on the inner side and preventing contaminants from entering from the outside.

For proper installation, the shaft must be clean, free of burrs or marks, and the sealing surface must be in good condition. The seal is inserted perpendicular to the shaft, with a tube or spacer that presses on the outer ring, never on the lip. Before fitting it, lubricate the lip with the same grease or oil used in the equipment. If the housing has burrs or the shaft shows wear, the seal may leak even if the size is correct.

If you need an equivalent or a nearby size, send us part number 6758 along with the shaft and housing dimensions. A photo of the old part or the assembly drawing also works. With that data we review alternatives within the same DBH line or from other brands we carry, and we confirm which option fits without modifying the housing. You don't need to have the exact number: the dimensions are enough.
