The DBH 8689 is a radial shaft seal designed to retain oil or grease on a rotating shaft while keeping dust and water out. It fits into a housing and seals against the shaft, making it a common replacement part in gear reducers, pumps, electric motors, and other power transmission equipment. MR Industrial Accessories supplies this brand and helps you select the correct seal for your application.
This seal carries the DBH 8689 designation and has a shaft diameter of 48 mm, a housing diameter of 72 mm, and a height of 10 mm. The Lx design means it has both a sealing lip and a dust lip, each with a spring. The primary lip holds the lubricant in, while the secondary lip blocks external contaminants. The number 8689 identifies the size and construction within the DBH line.
Radial shaft seals are found wherever a rotating shaft passes through a fixed housing and the lubricant must be separated from the environment. Typical equipment includes gear cases, centrifugal pumps, electric motors, conveyor rollers, and machine tools. They also appear in food and chemical processing when the elastomer is compatible with the fluids involved.
Proper installation calls for checking shaft hardness and surface finish, and making sure the housing is clean and free of burrs. Lubricate the lip before pressing the seal in, and keep it perpendicular to the shaft. If the shaft shows wear, an offset lip seal may be an option. Selection depends on speed, temperature, and the fluid being retained.
If you need a seal equivalent to the 8689, send the part number along with the shaft, housing, and height dimensions. We can also check whether the housing allows for an alternative. We work with leading seal brands and can advise you so the choice is right. MR Industrial Accessories responds promptly via WhatsApp or email.
