The DBH 9773 oil seal is a single-lip radial seal with design A 302, intended for rotating shafts where lubricant must be contained and contaminants blocked from entering. Its dimensions are 65.50 mm shaft diameter, 100.25 mm housing diameter and a height of 13.30/22.30 mm. It is used in gearboxes, pumps, electric motors and power transmission equipment that operate with oil or grease and need a reliable barrier at the point where the shaft passes through the housing.

This DBH 9773 oil seal has a shaft diameter of 65.50 mm, a housing diameter of 100.25 mm and a height of 13.30/22.30 mm. Design A 302 corresponds to a radial shaft seal with a sealing lip and metal case, suitable for press fitting into the housing. The double height indicates that the part has a stepped profile or a section that can accommodate a spring or an auxiliary lip, depending on the manufacturer's execution. It is a specific size that is not always replaced by a standard catalog seal, so it is best to verify the housing geometry before choosing a substitute.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment where the shaft rotates on bearings and oil or grease is present. It is also found in agricultural machinery, process equipment and hydraulic systems that require containing the lubricant inside the sump and preventing dust or water from entering the bearing. In all cases, the seal works on a ground shaft surface and a machined housing with the appropriate tolerance.

To mount this oil seal, verify that the shaft diameter is within the tolerance recommended for radial seals and that the contact surface has no grooves or wear. The housing must be clean, free of burrs and have an entry chamfer so the lip is not damaged during mounting. Lubricate the lip with the same grease or oil used in the equipment before inserting it and press perpendicularly until it seats at the bottom. If the shaft shows wear, consider a seal with an offset lip or a repair sleeve.

If you need an equivalent or a nearby size, the most practical approach is to send us part number 9773 along with the shaft, housing and height dimensions, and a photo of the original part. With that data we can look for alternatives in other brands or confirm whether a standard size will fit. We can also advise you on the lip type, elastomer material and operating temperature so the selection is correct. Not all sizes are interchangeable, so prior verification avoids unnecessary downtime.
