The DBH 6371Sil radial shaft seal is a lip seal designed to stop oil or grease from passing through rotating shafts and protect the interior of gearboxes, pumps and motors. With dimensions of 44.45 mm shaft, 66.62 mm housing and 16.70 mm height, and an Mx design, it is press-fitted into the housing and works on the shaft with a flexible lip. It is a wear part that should be replaced at the first sign of leakage.

This item is a radial shaft seal from the DBH line, identified with part number 6371Sil. Its dimensions are 44.45 mm shaft diameter, 66.62 mm housing diameter and 16.70 mm height. The Mx design corresponds to a configuration with a sealing lip and metal body, suitable for retaining lubricant and excluding contaminants in equipment with rotating motion. The exact designation lets you cross-reference the part number with the manufacturer's data sheet before ordering.

Seals of this type are used in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. Their function is twofold: prevent oil leaks to the outside and stop dust, water or particles from entering that accelerate wear on bearings and gears. In food, chemical or water treatment plants, choosing the right lip material makes the difference in service life.

To install it, verify that the housing is clean, free of burrs and at the 66.62 mm dimension. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a support tube that pushes on the outer diameter, never on the lip. The shaft must be polished and free of grooves in the contact area. If the previous seal failed, also check bearing clearance and operating temperature.

If you need a nearby size or an equivalent, send us part number 6371Sil along with the shaft, housing and height dimensions. You can also send a photo of the old seal or the housing drawing. At MR Accesorios Industriales we check the data against the manufacturer's data sheet and offer you alternatives within the same radial seal category, respecting the design and material.

If you have any doubt about the application, peripheral speed or lubricant type, consult us before installing. A poorly selected seal can fail within hours and damage the bearing.
