The DBH 8004 oil seal is a single-lip radial shaft seal designed for 26 mm rotating shafts and 42 mm housings. Its height of 8 mm at the mounting area and 17 mm at the lip helps accommodate slight eccentricity and misalignment. It is made of an elastomer resistant to oils and greases, with a steel spring to maintain contact pressure. It is a key part for preventing lubricant leaks and the entry of contaminants in gearboxes, pumps and electric motors.

The DBH 8004 is a radial shaft seal with the designation 8004. Its main dimensions are: shaft diameter 26 mm, housing diameter 42 mm and height 8.00/17.00 mm. The A 040 design corresponds to a sealing lip with a spring, suitable for rotating shafts. This type of oil seal is press-fitted into the housing and seals against the shaft by means of an elastomeric lip that compensates for slight misalignment. The total height of 17 mm includes the outer lip, which facilitates installation in spaces with limited access.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In industry, it is used to retain oil or grease in bearings and to prevent dust or moisture from entering the mechanism. It is also common in agricultural machinery, construction equipment and production lines where rotating shafts are exposed to severe conditions. Its compact size makes it suitable for tight spaces.

To correctly select an oil seal such as the DBH 8004, verify that the shaft and housing diameters match the dimensions indicated. The shaft surface must have suitable hardness and roughness to prevent premature lip wear. During installation, lubricate the lip with the same oil or grease used in the equipment and make sure not to damage it with sharp edges. The 8/17 mm height allows some axial tolerance, but it is important that the oil seal sits perpendicular to the shaft for effective sealing.
