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 it is necessary to retain lubricant and exclude contaminants. At MR Accesorios Industriales we sell it as part of our line of seals and oil seals for industrial maintenance.

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

Typical applications of 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: to retain the lubricant inside the assembly and to prevent 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 rest of the dimensions must be validated with the manufacturer's data sheet or with a direct measurement on the original part. The A 377-R AH design provides guidance on the type of lip 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 hitting it. Poor alignment or a damaged lip causes premature leaks.

If you need an equivalent or a nearby size, the most practical thing is to send us the part number 1144Tef or the measurements taken with a caliper: shaft diameter, housing diameter and height. With that data we can look for alternatives within the DBH line or other brands we carry. We can also guide you if the original seal is not available and a solution needs to be adapted. The idea is that you don't end up with equipment down because of a sealing part.
