The DBH 8677 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and exclude contaminants. Its dimensions of 66.70 mm shaft, 95.25 mm housing and 12.70 mm height place it in equipment with medium-section shafts. It is a wear part: when the lip hardens or a leak appears, it is replaced with a seal of the same designation or an equivalent size.

This item is a radial shaft seal from the DBH brand, identified with code 8677. Its dimensions are 66.70 mm shaft diameter (d), 95.25 mm housing diameter (D) and 12.70 mm height (h). The Lz design corresponds to a seal with a sealing lip and a standard construction configuration for rotating shafts. It is made of elastomer with a metal reinforcement and retaining spring, although the manufacturer's data sheet confirms the exact compound and the service temperature range.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases it performs two functions: preventing oil or grease from leaking out and blocking the ingress of dust, water or particles that accelerate wear on bearings. It is commonly found in equipment where the shaft rotates at moderate speeds and lubrication is by splash or circulation.

To select and install a seal, three things must be verified: that the shaft and housing diameters match the values of the part, that the height is compatible with the housing depth, and that the lip design is suitable for the direction of rotation and the working pressure. During installation, lubricate the lip with the same oil used in the equipment, insert it perpendicular to the shaft and avoid hitting or deforming it. A poorly seated lip is the most common cause of premature leaks.

If you need a seal equivalent to the 8677 or a nearby size, send us the code, the shaft, housing and height dimensions, and a photo of the old part if you have one. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the seal is mounted in an assembly with bearings or housings that you need to renew at the same time.
