The DBH 5881 seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and stop the entry of dust, water or particles. With 30 mm shaft, 72 mm housing and 12 mm height, it is a common size in gearboxes, pumps and transmission equipment. At MR Accesorios Industriales we carry it within our line of seals and radial shaft seals.

This item is a radial shaft seal from the DBH line, identified with the code 5881. Its nominal dimensions are 30 mm shaft diameter, 72 mm housing diameter and 12 mm height. The Lx design corresponds to a single sealing lip with an outer metal body, intended for rigid housings and rotating shafts. The lip works on the shaft with slight interference, while the outer diameter is press-fitted into the housing to ensure static sealing.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases it serves the same function: containing the oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used as a secondary barrier in equipment with washing or exposure to splashes.

To select and install a seal, verify that the shaft diameter and housing diameter match the part dimensions, that the shaft has no burrs or wear on the sealing track, and that the housing surface is clean and free of dents. The lip is lubricated before installation and inserted perpendicular to the shaft, without tilting it, using a tube or spacer that presses on the metal body and not on the lip.

If you need an equivalent or a nearby size, the most practical approach is to send us the code 5881, the shaft dimension, the housing dimension and the height, or directly a photo of the old part with a caliper next to it. With that data we review alternatives within the DBH line and other brands we carry, and we confirm which option fits without modifying the housing.

At MR Accesorios Industriales we work with seals and radial shaft seals alongside bearings, housings, power transmission and lubricants, so we can help you solve the complete assembly and not just the individual part. Send the code 5881 or the dimensions on WhatsApp and we will quote you.
