The DBH 6825 oil seal is a single-lip radial seal that mounts on the shaft and against the housing to retain lubricant and block the entry of dust, water or particles. Its Lz design and its dimensions of 151.6 mm shaft, 178.2 mm housing and 12.7 mm height place it in large equipment, such as gearboxes, pumps and continuous process machines. MR Accesorios Industriales sells this brand and advises you so you can choose the correct size.

This item is a DBH 6825 radial shaft seal, identified by its designation 6825. Its dimensions are shaft (d) 151.6 mm, housing (D) 178.2 mm and height (h) 12.70 mm. The Lz design corresponds to a sealing lip with a specific configuration for rotating shafts, which works with the elastomer resting on the shaft and the metal case fixed in the housing. It is a replacement part for equipment where radial space is limited and a reliable barrier against leaks is needed.

Typical applications for a seal of this size appear in gearboxes, process centrifugal pumps, mixers, mills and power transmission equipment. In all cases it serves to keep the oil or grease inside the assembly and prevent contaminants from entering that accelerate wear on bearings and gears. It is also used on industrial fan shafts and large machine tools, where the seal is the first line of protection for the lubricant.

To install a radial shaft seal, check that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before inserting it and is pressed in with a tube of suitable diameter so as not to damage it. Selection depends on shaft speed, operating temperature and fluid type; if the original seal has a different design or material, it is advisable to compare the manufacturer's data sheet before replacing it.
