The DBH 5406 oil seal is a single lip radial seal that mounts on the shaft and against the housing to retain lubricant and block the entry of dust, water or particles. With a 27 mm shaft diameter, 44.40 mm housing and 9.52 mm height, and Lz design, it is a small, compact size, typical of gearboxes, pumps and low and medium power electric motors. MR Accesorios Industriales carries this official brand and will quote it for you on WhatsApp.

This item is a DBH radial shaft seal, part number 5406, with the following dimensions taken from its data sheet: shaft diameter 27 mm, housing diameter 44.40 mm and height 9.52 mm. The Lz design corresponds to a single sealing lip with a spring, designed for rotating shafts with oil or grease lubrication. The elastomer of the lip works against the shaft raceway, while the outer diameter seats in the housing, which must be machined with the correct diameter and depth so that the seal sits firm and centered.

Typical applications for a seal of this size are gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission equipment where oil leaks and the entry of contaminants must be prevented. It is also used on fan, mixer and conveyor shafts. Being a compact size, it usually appears in equipment where radial space is limited and reliable sealing is needed without adding bulky parts.

For proper installation, check that the shaft has no burrs, scratches or wear in the contact area: a shaft with a deep groove means the lip will not seal even if the seal is new. The housing must be clean, free of old sealant residue, and it is advisable to lubricate the lip with the same grease or oil as the equipment before inserting it. Do not hit the seal with pointed tools: use a tube or spacer that rests on the outer ring and drives it in perpendicular. If the equipment works with high vibration or temperature, consult us and we will evaluate an alternative compound or design.

If you need an equivalent or a nearby size, send us the full part number, the equipment manufacturer or the shaft, housing and height dimensions. With that data we search the DBH line and other brands we carry to give you a compatible alternative. We can also advise you if the original seal has a different design or if the housing accepts a greater width. The more precise the information, the faster we reach the right option.
