The DBH 1305/85 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. It is installed in cylindrical housings and runs on the shaft with an oil film that ensures sealing and low friction. Its A 429 design and dimensions of 150 mm shaft, 165 mm housing and 9/12 mm height make it suitable for heavy-duty industrial equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with the designation 1305/85. Its nominal dimensions are 150 mm shaft diameter (d), 165 mm housing diameter (D) and a height (h) of 9/12 mm. The A 429 design corresponds to a single-lip seal with spring, intended for lubricated rotating shafts. The variable height 9/12 mm indicates that the sealing lip extends 12 mm from the back, while the total height of the metal body is 9 mm. This configuration allows it to be mounted in housings with limited depth and ensures uniform contact on the shaft.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal prevents oil or grease leakage and protects the bearings from the ingress of dust, water or particles. Due to its size, it is used on large-diameter shafts, such as those found in heavy machinery, mills, industrial mixers and mining or cement equipment. It is also common in applications where the shaft rotates at moderate speeds and the working temperature does not exceed the limits of the standard elastomer.

To correctly select this oil seal, verify that the shaft diameter is within the recommended tolerance for radial seals, generally h11 or similar, and that the housing has a surface finish suitable for the outer diameter. Installation must be done with a tool that presses uniformly on the outer edge, never on the lip. Before installing, lubricate the lip with the same oil or grease that the equipment will seal. If the shaft shows wear or grooves, consider using a seal with an auxiliary lip or a wear sleeve. Correct alignment between shaft and housing is key to avoiding premature leaks.

If you need an equivalent oil seal or an adjacent size, the most practical approach is to send us the complete code 1305/85 or the current dimensions (shaft diameter, housing diameter and height). With that data, at MR Accesorios Industriales we can look for alternatives within the same DBH brand or other brands we carry. We can also advise you if the mounting space allows variants with standard height or double lip. Remember that the exact designation is the safest way to avoid errors: send it on WhatsApp and we will reply with the available options.
