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 a height of 11 mm, dimensions worth verifying against the drawing before replacing.
This item is a radial shaft seal from the DBH line, identified with the code 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 the retention of grease or oil in the presence of dirt. DBH is a brand MR sells, 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 off the passage of lubricant to the outside and preventing contaminants from entering. It is a wear part: over time the lip hardens or becomes marked, and leaks or noises appear. That is why it is worth checking every time the equipment is disassembled and replacing it 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 dents. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do so with a flat pusher so as not to deform it. The 11 mm height defines how far it protrudes from the housing, so do not force the position. If the shaft shows wear, consider a seal with the lip in another location so as not to repeat the failure.
If you need an equivalent, send us the code 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 sell. 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.

Frequently Asked Questions
- What dimensions does the DBH 1131Pol oil seal have?
- It corresponds to a 40 mm shaft, a 58 mm housing and an 11 mm height. These are the nominal dimensions of code 1131Pol and it is worth verifying them against the drawing or the old part before installing, because an error of tenths can cause leaks.
- What does the Lx-R AH design mean?
- It is the seal configuration: a main sealing lip and an auxiliary exclusion lip. That extra lip helps stop dust or water from entering from the outside, which is why it is used in equipment with a contaminated environment or frequent washing.
- How do I request a quote or an equivalent?
- Write to us on WhatsApp with the code 1131Pol and the shaft, housing and height dimensions. If you have the old seal, send a photo.
