The DBH 1374Tef radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. It is mounted in gearboxes, pumps, electric motors and power transmission equipment, where oil or grease must stay inside the assembly and dust or water cannot enter. Its A 434-R AH design corresponds to a standard single-lip configuration with spring, suitable for 85 mm shafts. 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 1374Tef. According to the product page data, it corresponds to a shaft of 85 mm diameter, with an A 434-R AH design. The housing and height values shown in the record are not valid for this part number, so the housing dimensions and width must be confirmed against the manufacturer's technical data sheet before purchasing. The A 434-R AH design indicates a lip configuration with spring, intended for continuous rotation applications with permanent lubrication.

Typical applications for a seal of this type include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all these cases, the seal serves two functions: preventing oil or grease leaks to the outside and blocking the entry of dust, water or particles that accelerate wear on bearings and gears. It is a relatively low-cost part but critical to the service life of the assembly.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the overall height. Rotation speed, working temperature and lubricant type also matter. Installation must be done with a clean, burr-free shaft, lubricating the lip before inserting it. It is advisable to use an installation tube or guide bushing to avoid damaging the lip, and to verify that the seal sits square to the shaft. If the shaft shows wear, consider a repair sleeve.

If you need a seal equivalent to the 1374Tef or a nearby size, the most practical approach is to send us the complete part number, the shaft, housing and height dimensions, and a photo of the old part if you have one. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the original seal is no longer available and a standard size has to be adapted.
