The DBH 9862Pol oil seal is a single-lip radial seal that mounts on a 76.30 mm shaft and fits into a 125.35 mm bore, with a height of 19.40 mm. Its A121-R design corresponds to a seal with a metal case and elastomer lip, intended to contain lubricant and exclude contaminants in rotating equipment. It is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates continuously. MR Accesorios Industriales carries this brand and advises you so you can choose the correct seal for your application.

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 configuration 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, verify 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 the oil or grease inside the assembly and preventing the ingress of dust, water or particles. It is also used as a closure on bearings and bushings that require protection against the elements. If your equipment operates with vibration or misalignment, it is advisable to check the condition of the shaft before replacing the seal.

To select this seal correctly, 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. During installation, 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.
