The DBH 1205/85 oil seal is a single-lip radial shaft seal that mounts on the shaft and against the housing to contain lubricant and stop the entry of dust, water or particles. With a 27 mm shaft diameter, 42.70 mm housing diameter and 7.90 mm height, it solves sealing in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates and the bearings must be protected. MR Accesorios Industriales supplies it as an official brand.

You are dealing with a radial shaft seal of Mx design, with the dimensions marked in the designation: 27 mm shaft diameter, 42.70 mm housing diameter and 7.90 mm height. The sealing lip works on the rotating shaft and the outer diameter is press-fitted into the housing. That combination of dimensions corresponds to a compact section, designed for tight spaces where a taller seal does not fit. The DBH brand is an official brand that MR supplies, so the code 1205/85 is ordered exactly as it appears on the product page.

Typical applications for this seal appear in equipment with rotating shafts and internal lubrication: gearboxes, centrifugal pumps, electric motors, gear reducers, mixers and conveyors. It is also used as a secondary barrier in bearings and bushings that work with grease or oil. In all those cases it performs two functions at the same time: it retains the lubricant inside the assembly and prevents contaminants from entering from outside, which is what ultimately shortens bearing life.

To install it properly, verify that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and install the seal with a flat tool that rests on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an offset lip. The selection depends on speed, temperature and the type of lubricant, data that should be confirmed before requesting a quote.

If the code 1205/85 is not the one you need, an equivalent or a nearby size can be found within the same radial shaft seal category. For that, it is advisable to send the measured shaft diameter, housing diameter and height, plus a photo of the old seal and the type of lubricant the equipment uses. With that data it is compared against the available alternatives and the option that best fits the assembly is proposed, without inventing dimensions that are not in the catalogue.
