The DBH 1131Pol radial shaft seal is a lip seal mounted in a machine housing to retain lubricant and block the entry of dust, water or particles. Its Lx-R AH design combines a sealing lip with an auxiliary exclusion lip, making it suitable for equipment with moderate exposure to contaminants. It is installed on a 40 mm shaft, in a 58 mm housing and with an 11 mm height, dimensions that should be verified against the drawing before replacement.

This item is a radial shaft seal from the DBH line, identified with the part number 1131Pol. Its nominal dimensions are 40 mm shaft, 58 mm housing and 11 mm height. The Lx-R AH design indicates a configuration with a sealing lip and an auxiliary exclusion lip, intended to improve grease or oil retention in the presence of dirt. DBH is an official brand that MR supplies, so the product arrives with its original designation and can be checked against the manufacturer's data sheet.

Typical applications for a seal of these dimensions appear in gearboxes, pumps, electric motors, transmission shafts and process equipment. In all cases it fulfills the function of closing the passage of lubricant to the outside and preventing contaminating agents from entering. It is a wear part: over time the lip hardens or becomes marked, and leaks or noise appear. That is why it should be inspected every time the equipment is disassembled and replaced if it shows loss of elasticity or visible wear.

To install it properly, check that the shaft has no burrs or grooves in the sealing area and that the housing is clean and free of impacts. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do so with a flat pusher to avoid deforming it. The 11 mm height defines how much it protrudes from the housing, so do not force the position. If the shaft shows wear, consider a nearby size or a seal with the lip in another location to avoid repeating the failure.

If you need an equivalent or a close size, send us the part number 1131Pol along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. With that data we can look for an alternative within the same DBH line or from another brand we supply. It also helps if you tell us the type of lubricant and the rotation speed of the equipment, because they influence the selection of the lip material.
