The DBH 8490 radial shaft seal is a lip seal designed to close off lubricant and prevent contaminants from entering rotating equipment. With dimensions of 40 mm shaft, 58 mm housing and 11.30 mm height, it is press-fitted into the housing and runs on the rotating shaft. It is a key part for maintaining lubrication and extending the service life of bearings and gears in industrial machinery.

This DBH 8490 oil seal has an A 075 design and standardized dimensions: shaft diameter 40 mm, housing diameter 58 mm and height 11.30 mm. The sealing lip, made of elastomer resistant to oils and greases, provides an effective barrier against leaks and particles. Its construction includes a metal reinforcement that gives it rigidity to withstand installation pressure and operating conditions. It is a direct replacement part for applications requiring these specific dimensions.

It is used in gearboxes, pumps, electric motors, compressors and power transmission equipment. It is commonly found in production lines, conveyors and agricultural or road machinery. Its main function is to retain lubricant inside the assembly and prevent external agents such as dust, water or chips from entering the bearing or gear, reducing premature wear and contamination-related failures.

For correct installation, verify that the shaft and housing are clean, free of burrs and marks. Lubricate the seal lip with the same grease or oil used in the equipment before inserting it. Place it perpendicular to the shaft and press evenly until it seats at the bottom of the housing. Avoid striking the sealing lip. If the shaft shows wear, consider using a seal with an auxiliary lip or a wear sleeve to ensure tightness.
