The DBH 1397 radial shaft seal is a lip seal mounted on the shaft and inside the housing to retain lubricant and exclude contaminants. Its dimensions of 20.00 mm shaft, 30.00 mm housing and 4.50 mm height make it suitable for tight spaces. It is a wear part that should be replaced when leaks or noise appear.

This item is a DBH 1397 radial shaft seal, identified by its designation 1397. According to the product page data, it has a shaft diameter (d) of 20 mm, a housing diameter (D) of 30 mm and a height (h) of 4.50 mm. The Lx design corresponds to a single-lip seal with spring, of compact section. It is a radial type seal, intended for rotating shafts, not for front faces or reciprocating movements.

Typical applications for a seal of this size include small pumps, low-power electric motors, light gearboxes, machine tools and transmission equipment. In all cases it fulfills the function of confining oil or grease inside the assembly and preventing the ingress of dust, water or particles. It is also used on fan, mixer and conveyor shafts where axial space is limited.

To install it correctly, verify that the shaft has no burrs or marks and that the sealing surface is polished. Lubricate the lip before inserting it and place the seal with a support tube that presses on the outer edge, never on the lip. Selection depends on shaft speed, working temperature and fluid type. If the original seal has another designation, we can look for an equivalent or neighboring size within the DBH line.
