The DBH 6129 radial shaft seal is a lip seal mounted in the housing that seals against the rotating shaft to contain lubricant and block the entry of dust, water or particles. With dimensions of 52.40 mm shaft, 76.17 mm housing and 7.93 mm height, and Lt design, it is a replacement part for equipment where axial space is limited and a reliable seal is needed. MR Accesorios Industriales carries it as an official brand.

This item is a DBH 6129 radial shaft seal, identified by its designation 6129. Its attributes are: shaft diameter 52.4 mm, housing diameter 76.17 mm, height 7.93 mm and design Lt. The Lt design corresponds to a seal with a sealing lip and metal body, intended for rotating shafts with lubrication. These dimensions are what define compatibility with the housing and the shaft; any replacement must respect them to avoid leaks or premature wear.

Typical applications for a seal of this size include gearboxes, pumps, electric motors, reducers and power transmission equipment. In all cases it performs the function of retaining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is a critical part in preventive maintenance: replacing it in time prevents lubricant loss and greater damage to bearings and gears.

To install it, check that the shaft and housing are clean, free of burrs or marks, and that the shaft surface has the appropriate hardness and roughness. Lubricate the lip before inserting it and place the seal perpendicular, without striking it directly on the lip. If the housing shows wear, consider a nearby size or a seal with greater height. The final selection should be confirmed against the manufacturer's data sheet for that code.

If you need an equivalent or a nearby size, send us the code 6129 along with the shaft, housing and height dimensions, and the type of application. With that data we can look for alternatives within the DBH line or from other brands we carry. We can also advise you if the Lt design is not the right one for your equipment and you need another type of lip or material.
