The DBH 5773 oil seal is a single-lip radial seal that mounts on the shaft and inside the housing to retain lubricant and block the ingress of dust, water or particles. With 37.70 mm shaft diameter, 55.00 mm housing diameter and 8.00 mm height, it is a commonly used size in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales supplies this brand and helps you confirm the size before requesting a quote.

The DBH 5773 is a radial shaft seal with an Mz design, with the three dimensions that define its mounting: shaft diameter 37.70 mm, housing diameter 55.00 mm and height 8.00 mm. The sealing lip runs against the rotating shaft and the outer diameter is press-fitted into the housing. The designation 5773 is the part number that identifies this size within the DBH line, so it is worth having it at hand when ordering the replacement.

It is used in equipment where a shaft rotates inside an oil or grease sump: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and agricultural or road machinery. In all these cases the seal performs two functions at the same time: it prevents lubricant from escaping to the outside and it stops the ingress of contaminants that accelerate wear on bearings and gears.

To select it correctly, check that the shaft and housing diameters match the values on the product page. Check the condition of the shaft surface: a new lip on a scratched or burred shaft will not seal. During installation, lubricate the lip, seat the seal perfectly perpendicular and push it in with a tube or spacer of the outer diameter, never striking the lip. If the housing has burrs, clean it before seating.

If you need a nearby size or an equivalent from another brand, send us part number 5773 and the shaft, housing and height dimensions. With that data we look for the alternative within the DBH line or other brands we supply. If the seal goes on critical equipment, we can also advise you on the lip type and material according to the fluid and working temperature.
