The DBH 6812Pol radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering equipment with a rotating shaft. Its dimensions of 140 mm shaft diameter, 160 mm housing diameter and 13 mm height place it in the medium-to-large seal range, common in gearboxes, pumps and industrial transmissions. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

The DBH 6812Pol is an Lx design oil seal, with the dimensions shown in its designation: 140 mm shaft diameter, 160 mm housing diameter and 13 mm height. The Lx design corresponds to a seal with a single sealing lip and metal body, designed to be press-fitted into the housing and seal against the shaft. It is a standard replacement part within the radial shaft seal category, and its part number lets you quickly identify the exact size you need to replace.

This type of seal is used in equipment where a shaft rotates inside a lubricated housing: gearboxes, reducers, centrifugal pumps, electric motors, rollers and conveyors. In industrial, food or process plants, the seal serves the dual purpose of retaining oil or grease and blocking dust, water or debris that could damage the bearings. That is why it is a critical part in preventive maintenance: a worn seal shows up as lubricant leaks or dirt ingress.

To install a seal like the 6812Pol, check that the shaft diameter and housing diameter match the indicated values, that the shaft surface has no burrs or excessive wear, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and fit the seal perpendicular, with a suitable tool, without striking it directly. If the shaft shows a marked wear groove, consider shifting the seal slightly or replacing the shaft to ensure sealing.

If you need a nearby size or an equivalent from another brand, send us the full part number, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can look for the alternative that best fits your equipment. We can also advise you on the lip type and seal material according to the fluid, temperature and operating speed, always confirming against the manufacturer's data sheet.
