This item is a DBH radial shaft seal with the designation 9862Pol. Its dimensions are shaft (d) 76.30 mm, housing (D) 125.35 mm and height (h) 19.40 mm. The A121-R design indicates a specific construction within the DBH line: steel case with sealing lip and retaining spring. It is not a double-lip seal or a mechanical seal; it is a friction component that works on the shaft and against the housing. Before installing it, check that the dimensions match those of your equipment's housing and shaft.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, medium-power electric motors and transmission shafts. In all cases it performs two functions: retaining oil or grease inside the assembly and preventing the entry of dust, water or particles. It is also used as a closure on bearings and bushings that require protection against the weather. If your equipment operates with vibration or misalignment, it is advisable to check the condition of the shaft before replacing the seal.

To correctly select this seal, take into account the rotation speed, working temperature and type of lubricant. The A121-R design is intended for shafts with a ground surface and adequate hardness; a scratched or worn shaft causes leaks even if the seal is new. When installing it, lubricate the lip with the same oil used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the housing has burrs or corrosion, correct it before installing. These precautions extend the service life of the seal.
