The DBH 5372 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 64 mm shaft, 85 mm housing and 16 mm height place it in medium-sized transmission equipment and pumps. It is a wear part: when the lip hardens or the shaft gets marked, it should be replaced before oil loss damages bearings and gears.

This item is a DBH brand oil seal, identified with part number 5372. Its dimensions are 64 mm shaft diameter, 85 mm housing diameter and 16.00 mm height, with Lz design. The Lz design corresponds to a seal with a sealing lip and standard mounting configuration for rotating shafts. The 5372 designation is the reference you will find on the manufacturer's product page and the one you should cite when ordering spare parts or comparing alternatives.

Radial shaft seals of this size are used in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In food, chemical or water treatment plants, the sealing function is twofold: it prevents oil or grease from escaping and wash water or dust from entering the bearing. They also appear in older machines where the housing already shows marks and the fit must be checked before installing the new seal.

To select a seal properly, the dimension alone is not enough: you must check the condition of the shaft, the surface roughness, the concentricity of the housing and the type of lubricant. A scratched or worn shaft means the lip does not seat evenly and leakage reappears within a few hours. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it with pointed tools. If the housing is damaged, consider a repair sleeve.

If you cannot find part number 5372 or you need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part and the housing. With that data we look for the equivalent in DBH or another brand we carry and confirm the alternative. We can also check whether the Lz design is right for your application or whether another lip profile is better.
