The DBH 6801 radial shaft seal is a lip seal designed for rotating shafts, with dimensions of 39.42 mm shaft diameter, 57.10 mm housing bore and 8.00 mm height. Its Mz design combines a main lip with a secondary exclusion lip, which improves lubricant retention and blocks the entry of contaminants. It is used in gearboxes, pumps, electric motors and power transmission equipment to prevent leaks and extend the service life of bearings and gears.

This DBH 6801 oil seal has a designation that corresponds to the standard size of 39.42 mm shaft diameter (d), 57.10 mm housing bore diameter (D) and 8.00 mm height (h). The Mz design indicates a configuration with a main sealing lip and a secondary exclusion lip, mounted on a metal case that is press-fitted into the housing. It is manufactured with elastomers resistant to mineral oils and greases, and its internal spring maintains contact pressure on the shaft.

Typical applications for this oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all these cases, the seal prevents lubricant leakage and protects the bearings from dust, water or abrasive particles. It is a critical part in the maintenance of industrial, agricultural and transport machinery.

To select the correct oil seal, verify that the shaft and housing dimensions match those of the equipment. The shaft diameter must be within the recommended tolerance for radial shaft seals, and the housing must have a surface finish suitable for the press fit. During installation, lubricate the lip with the same oil or grease used in the equipment, avoid striking the spring and make sure the lip is not turned inside out. If the shaft shows wear, consider using a repair sleeve.
