A radial shaft seal built for rotating equipment, the DBH 6825 keeps lubricant where it belongs and keeps dust, water and other contaminants out. Its Lz lip configuration works against the shaft while the metal case seats in the housing. The dimensions are shaft 151.6 mm, housing 178.2 mm and width 12.7 mm, which puts it in larger assemblies such as gearboxes, pumps and continuous-process machinery. MR Industrial Accessories supplies this brand and can help you confirm the right reference.

The item carries the designation 6825 and falls within the DBH line of radial shaft seals. Reading the size is straightforward once you know the order: d is the shaft diameter at 151.6 mm, D is the housing bore at 178.2 mm, and h is the 12.70 mm width. The Lz design refers to the lip geometry, with the elastomer riding on the rotating shaft and the outer case held by the housing. It is a replacement part for assemblies where radial space is tight and a dependable barrier against leakage is required.

Seals in this size range show up in gearboxes, process centrifugal pumps, mixers, mills and power transmission drives. In each case the job is the same: hold oil or grease inside the assembly and block the particles and moisture that shorten bearing and gear life. Industrial fan shafts and large machine tools also use this size, where the seal acts as the first line of defense for the lubricant.

Installation calls for a clean shaft with no burrs or deep scoring in the contact zone, plus a housing that is clean and undistorted. Lubricate the lip before pressing the seal in, and use a tube or driver of the correct diameter so the lip is not damaged. Selection should account for shaft speed, operating temperature and the fluid being sealed. If the seal you are replacing uses a different lip design or elastomer, compare the manufacturer's data before committing to the swap.

For an equivalent, send the code 6825 or the current dimensions on WhatsApp. We cross-reference shaft diameter, housing diameter and width against the options we handle to find the closest fit. We can also advise when the original seal has a different design or when the housing can take an alternative width.

Have the seal code, the shaft and housing measurements, and the lubricant type used by the equipment ready before you request a quote. With that information we can reply with the purchasing options. Message us on WhatsApp and we will help you close out the replacement.
