The DBH 1144Tef radial shaft seal is a lip seal designed to be mounted on an 80 mm shaft and prevent oil or grease leaks in rotating equipment. Its A 377-R AH design combines a sealing lip with a metal body that fits into the housing. It is used in gearboxes, pumps, electric motors and transmissions where lubricant must be retained and contaminants excluded. At MR Accesorios Industriales we sell it as part of our seals and oil seals line for industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified by the designation 1144Tef. According to the product page data, it is intended for an 80 mm diameter shaft. Design A 377-R AH corresponds to a specific lip and case configuration that fits standard housings. The housing and height values are confirmed against the manufacturer's data sheet before quoting. It is a sealing component for rotating shafts, not a bearing or a bushing.

Typical applications for a radial shaft seal such as the DBH 1144Tef include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all these cases, the seal serves two functions: retaining lubricant inside the assembly and preventing the entry of dust, water or particles. It is also used on fan, mixer and conveyor shafts. It is a wear part that should be replaced when an oil leak appears or when the lip shows hardening or cracks.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the height. In this case, the confirmed data is the 80 mm shaft; the remaining dimensions must be validated with the manufacturer's data sheet or by measuring the original part directly. Design A 377-R AH provides guidance on the lip type and material, but it does not replace dimensional verification. During assembly, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it. Poor alignment or a damaged lip causes premature leaks.

If you need an equivalent, the most practical approach is to send us code 1144Tef or the dimensions measured with a caliper: shaft diameter, housing diameter and height. With that data we can look for alternatives within the DBH line or from other brands we sell. We can also advise you if a solution has to be adapted. The goal is for you not to have your equipment down because of a sealing part.
