The DBH 8457/85 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 26 mm shaft diameter, 37 mm housing diameter and 7 mm height, and Lx design, it is press-fitted into covers, gearboxes and pumps to retain lubricant and stop dust or water from entering. It is a wear part: it should be replaced when leakage appears.

This item is a DBH brand radial shaft seal, identified by the code 8457/85. Its dimensions are 26.00 mm shaft diameter (d), 37.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a single-lip seal with spring, with the lip facing the side of the fluid to be retained. The lip elastomer runs on the shaft and the outer metal case ensures the fit in the housing.

It is used in equipment with rotating shafts where lubricant must be contained: gearboxes, centrifugal pumps, electric motors, mixers, drive shafts and rollers. It also appears in applications where, in addition to retaining oil, dust, chips or process water must be excluded. It is a common component in preventive maintenance and in repairs of equipment that has already been in service for years.

To select the seal, verify that the three dimensions match the shaft and housing: 26 mm shaft, 37 mm housing and 7 mm height. Check the condition of the shaft surface: if it has a groove or wear, the new lip will not seal properly and you should consider a replacement shaft or a seal with the lip in a different position. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular and strike only on the metal case, never on the elastomer.

If the code 8457/85 is not the one shown on your equipment, send us the dimensions of the old seal (shaft diameter, outer diameter and height) and a photo of the part. With that data we look for the equivalent in DBH or in another brand we carry. We also confirm whether the Lx design is suitable for your application or whether another type of lip is better.
