The DBH 5030 radial shaft seal is a lip seal that closes off the passage of lubricant and blocks dust and moisture from entering at the point where a shaft passes through a housing. It is press-fitted into the housing and runs on the rotating shaft, with a flexible lip that maintains contact. It is a wear part: when oil loss or dirt ingress appears, it is replaced.

This item is a seal from the DBH brand, identified with the part number 5030. Its dimensions are 20.00 mm shaft diameter, 47.00 mm housing diameter and 10.00 mm height. The indicated design is Lz, which defines the geometry of the lip and the metal case. With those three values the seal is located in the housing and the lip is verified to rest on the shaft surface. If the shaft or housing is worn, the seal may not seat properly even if the dimensions match.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, rollers and power transmission equipment where there is a shaft rotating inside a housing with oil or grease. They also appear in agricultural machinery, conveyor lines and process equipment. The function is twofold: retain the lubricant inside and prevent particles, wash water or dust from entering toward the bearings and gears. In environments with a lot of dirt or frequent washing, the seal is the first barrier.

To select a seal, the diameter alone is not enough: you must check the condition of the shaft, the roughness of the surface, the concentricity of the housing and the rotation speed. A scratched or burred shaft damages the lip 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 tap on the outer ring, never on the lip. If the housing has burrs, clean it before inserting the seal. The Lz design has a lip orientation that should be respected.

If you need an equivalent from another brand, send us the part number stamped on the old seal, the shaft and housing dimensions, and a photo of the part. With that we will tell you whether the DBH 5030 is the correct one or whether another design is required. We can also check whether the seal goes with an additional lip or with a spring. The more data you send, the faster the part is identified without taking the equipment out of service.
