This item is a radial shaft seal from the DBH line, identified with the designation 9920Pol. Its dimensions are 39.42 mm shaft diameter, 80.27 mm housing diameter and 22.00 mm height. The A 344-R Bidi design corresponds to a double-lip seal, intended to retain lubricant and block dust or water from entering from the outside. It is a sealing part that is press-fitted into the housing and rests its lip on the moving shaft.

Typical applications for this type of seal include gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a lubricated housing. The A 344-R Bidi design is useful in assemblies where the seal must retain grease or oil and at the same time prevent contaminants from entering, as occurs in dusty or humid environments. It is also used in older equipment where an original seal needs to be replaced with an equivalent size.

To correctly select this seal, verify that the shaft diameter, housing diameter and height match the values of the part being replaced. Installation must be done with a clean shaft, free of burrs or marks that could damage the lip, and with the housing free of debris. It is advisable to lubricate the lip before installing and use an installation tool that prevents deformation. Shaft eccentricity and surface roughness affect the service life of the seal.
