The DBH 9421 radial shaft seal is a lip seal that stops oil or grease from escaping at the point where a shaft passes through a housing. Its Lx design combines a sealing lip with a metal case that fits under pressure. It is used in gearboxes, pumps, electric motors and transmission equipment to retain lubricant and prevent the entry of dust or water.

This item is identified by the code 9421 and corresponds to a seal with a 38 mm shaft, 54 mm housing and 10 mm height. The Lx design indicates a single-lip configuration with a metal reinforcement, suitable for press fitting into a cylindrical housing. The nominal shaft dimension is 38.00 mm, the housing dimension is 54.00 mm and the total width is 10.00 mm. These are the values you must verify before replacing a worn part.

Radial shaft seals of this size are found in rotating equipment where lubricant must be contained and contaminants excluded. They appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. They are also used in agricultural and industrial applications where the shaft rotates on bearings and a barrier against dust, wash water or chips is needed. If the equipment works with a lot of dirt, it is best to check the condition of the lip frequently.

To select the correct seal, in addition to the dimensions, take into account the shaft speed, the working temperature and the type of lubricant. The Lx design is suitable for moderate speeds and normal operating conditions. During fitting, lubricate the lip before inserting it, check that the shaft has no burrs or marks and place the seal perpendicular to the shaft with a support tube. A damaged lip or a scratched shaft causes leaks even if the dimension is correct.
