The DBH 1142Tef radial shaft seal is a lip seal designed to be mounted on an 85 mm diameter shaft, with an A 375-R AH design that combines a sealing lip and a dust lip. Its function is to retain lubricant inside the housing and prevent the ingress of contaminants, dust and water, protecting bearings, bushings and other moving parts. It is a key component in rotating equipment where sealing integrity and lubricant durability define the service life of the assembly.

This item is a radial shaft seal from the DBH brand, identified with the designation 1142Tef. According to the product page data, it is intended for an 85 mm diameter shaft, with an A 375-R AH design. The housing dimensions and height are confirmed against the manufacturer's technical data sheet at the time of quoting. The A 375-R AH design corresponds to a seal with a sealing lip and an auxiliary exclusion lip, suitable for applications with moderate exposure to dust or dirt.

Typical applications for this type of seal include gearboxes, pumps, electric motors, rollers and power transmission equipment. In all cases, the seal works on a rotating shaft and against a stationary housing, retaining the oil or grease and blocking the passage of external particles. It is frequently found in equipment where the 85 mm shaft is a mounting standard, such as certain models of gear reducers and continuous process machines.

To correctly select and mount a radial shaft seal, take into account the shaft diameter, the housing diameter, the overall height and the type of lubricant. The lip must rest on a ground surface free of splines, with adequate hardness to prevent premature wear. During mounting, lubricate the lip with the same service oil or grease and verify that the internal spring is correctly seated. Avoid striking the seal with sharp tools.

To quote the seal, the most practical approach is to send us the complete part number, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if the A 375-R AH design does not suit your application and it is worth evaluating another type of lip or material.
