The DBH 9780 radial shaft seal is a lip seal designed for 14 mm rotating shafts, with a 20 mm housing bore and 3 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, so correct selection of dimensions and lip design is key to achieving long service life in industrial equipment.

This item is a DBH 9780 radial shaft seal, identified by its numeric designation. Its dimensions are shaft (d) 14 mm, housing bore (D) 20 mm and height (h) 3.00 mm, with an Lt design. The Lt design corresponds to a single retaining lip, suitable for applications where axial space is limited and an effective barrier against oil or grease leaks is required. The 9780 nomenclature makes it easy to locate within the DBH line that MR sells.

Typical applications for a seal of these dimensions include small electric motors, centrifugal pumps, gear reducers, gearboxes, compressors and power transmission equipment. It is also used in machine tools, packaging equipment and centralized lubrication systems. In all cases, the seal protects the bearings and prevents lubricant contamination, helping to maintain assembly reliability and reduce unplanned downtime for corrective maintenance.

For installation, verify that the shaft has adequate hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the seal before inserting it and use an installation tube that bears on the outer diameter, never on the lip. The 3.00 mm height requires a housing with sufficient depth and a correct press fit. If the equipment runs at high peripheral speed or elevated temperatures, consult MR to evaluate the lip material and elastomer type.

If you need an equivalent seal, the most practical approach is to send us the 9780 code or the current dimensions (shaft, housing bore and height) via WhatsApp. You can also indicate the equipment where it is installed and a photo of the original seal. With that data, at MR Accesorios Industriales we check alternatives within the DBH line and other brands we sell, always respecting the critical dimensions so as not to compromise sealing.
