The DBH 8436 radial shaft seal is a lip seal designed for rotating shafts with a 35 mm diameter, a 72.50 mm housing bore and a 16 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles, protecting bearings and bushings. It is press-fitted into the cavity and runs against the shaft surface, which must be ground and lubricated. It is a wear part that should be checked at every maintenance interval.

This DBH 8436 oil seal has a shaft diameter of 35 mm, a housing bore diameter of 72.50 mm and a height of 16.00 mm. The A 053 design refers to the construction geometry of the lip and the metal case. The 8436 designation identifies the size within the DBH line. It is a single-lip radial shaft seal with a metal outer case and elastomer, intended for rotating shafts with permanent lubrication. It is installed in cylindrical housings and seals against the shaft by means of the flexible lip.

It is used in gearboxes, pumps, electric motors, power transmission equipment and general machinery where a shaft rotates inside a lubricated housing. It also appears in applications exposed to dust or splashes, where the seal prevents lubricant contamination. It is commonly found in equipment in the food, chemical and process industries, provided the lip material is compatible with the fluid and the working temperature.

To select the correct seal, verify that the shaft, housing and height dimensions match those of the record. The shaft must be ground, with no splines or burrs in the sealing area, with adequate hardness and roughness. The housing must have an entry chamfer so as not to damage the lip. Lubricate the lip before mounting and install the seal with a flat tool that bears on the outer diameter, never on the elastomer. If the shaft shows wear, consider a repair sleeve.

If you need a nearby size or an equivalent, send us the 8436 code together with the shaft, housing and height dimensions. The code stamped on the old seal or a photo of the part also works. With that data we check whether there is an alternative in the same series or in another brand that MR carries. Do not replace by approximation: one millimeter of difference in the housing can cause leaks or a forced fit.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals.
