The DBH 9311 radial shaft seal is a lip seal that is mounted in the housing of a component and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 30 mm shaft, 60 mm housing and 8 mm height, it is a commonly used size in gearboxes, pumps and electric motors. At MR Accesorios Industriales we quote it by WhatsApp.

This item is a DBH 9311 radial shaft seal, identified with the designation 9311 and the Lx design. Its dimensions are 30 mm shaft diameter (d), 60 mm housing diameter (D) and 8 mm height (h). The Lx design corresponds to a seal with a sealing lip and metal body, intended to be press-fitted into the cavity with the lip resting on the shaft. That combination of dimensions places it among medium-sized seals, in high demand in industrial maintenance.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a housing and oil or grease must be contained. It is also used in industrial washing machines, mixers and conveyors. In all those cases it performs two functions: preventing lubricant leaks to the outside and blocking the entry of contaminants that wear bearings and bushings.

For installation, check that the shaft is clean, without burrs or marks, and that the surface where the lip runs has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or spacer that rests on the outer edge, never on the lip. If the housing has a shoulder or radius, respect the seating depth. A poorly installed seal is damaged at the lip and loses sealing within a few hours of operation.

If you need an equivalent or a nearby size, send us the code 9311 or the dimensions 30 x 60 x 8 mm by WhatsApp. You can also send the code stamped on the old seal or the equipment designation. At MR Accesorios Industriales we check the manufacturer's data sheet before offering you an alternative, because two seals with the same dimensions can differ in lip type, material or spring. That way you avoid buying a seal that does not correspond.
