The DBH 6142Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the ingress of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this brand as part of its line of industrial seals.

This item is a seal with A 079 design and the following dimensions: shaft diameter 20 mm, housing bore diameter 55.50 mm and height 11.00 mm. The A 079 design corresponds to a single-lip seal with spring, suitable for lubricated rotating shafts. The designation 6142Sil identifies the part within the DBH line. Always verify these three dimensions before replacing a seal, because a difference of tenths can cause leaks or overheating.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In all cases, the seal works on a shaft that rotates inside a fixed housing, separating the oil or grease from the outside environment. It is also used in equipment in the food, chemical and process industries, where contamination of the lubricant must be avoided.

For correct installation, the shaft must be clean, free of burrs or marks, and the sealing surface must have adequate roughness. The housing must be ground and free of damage. Lubricate the seal lip with the same oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows wear, consider a repair sleeve or a seal with an auxiliary lip. Selection depends on speed, temperature and the type of fluid.
