The DBH 1205/85 seal is a single-lip radial shaft seal that mounts on the shaft and against the housing to retain lubricant and stop dust, water or particles from entering. With a 27 mm shaft diameter, 42.70 mm housing diameter and 7.90 mm height, it handles sealing in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates and the bearings need protection. MR Accesorios Industriales sells it.

This is a radial shaft seal with an 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 runs 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 will not fit. DBH is a brand MR sells, so part number 1205/85 is ordered exactly as it appears on the product page.

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

For proper installation, check 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 presses on the outer diameter, never on the lip. If the shaft shows wear, consider a seal with an offset lip. Selection depends on speed, temperature and lubricant type, data worth confirming before requesting a quote.

If part number 1205/85 is not the one you need, an equivalent can be found within the same radial shaft seal category. For that, it helps 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 applicable options and the one that best fits the assembly is proposed.
