The DBH 6812 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions —140 mm shaft, 160 mm housing and 13 mm height— place it in medium and large power transmission equipment. MR Accesorios Industriales sells this brand and advises you so you can choose the right seal for your application.

This item is a DBH 6812 radial shaft seal, identified by its designation 6812. Its attributes are specific: shaft diameter 140 mm, housing diameter 160 mm and height 13.00 mm. The Lx design corresponds to a seal with a sealing lip and metal outer body, designed to be press-fitted into the housing. The lip runs on the shaft with controlled interference to ensure dynamic sealing.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a housing and the oil or grease needs to be contained. It also appears in applications exposed to dust or water, where the seal acts as a barrier. It is a wear part: over time the lip hardens or wears and starts to lose oil, which makes replacement necessary.

To install it, check that the shaft is within tolerance and free of burrs, and that the housing has the correct diameter and depth. Lubricate the lip before inserting it and use a tube or press that presses on the metal body, never on the lip. If the shaft shows wear, consider a repair sleeve or a seal with an offset lip. The selection depends on speed, temperature and the fluid to be retained.

At MR Accesorios Industriales we check the data against the manufacturer's data sheet before quoting, to avoid installation errors.
