The DBH 5341 radial shaft seal is a lip seal that is mounted in the housing and closes on the shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 43 mm shaft, 56 mm housing and 6 mm height place it in medium-sized transmission and rotating equipment. It is a wear part: when oil loss or dirt ingress appears, it is replaced with a new one.

This item is a radial shaft seal from the DBH brand, identified with the part number 5341. Its dimensions are 43.00 mm shaft diameter, 56.00 mm housing diameter and 6.00 mm height. The Lz design corresponds to an oil seal with a sealing lip and spring, intended for rotating shafts with lubrication. The Lz nomenclature defines the geometry of the lip and the body, not the material, which is confirmed against the manufacturer's data sheet at the time of quoting.

Oil seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is a shaft rotating inside a housing with oil or grease. They also appear in rollers, mixers and conveyors. The function is twofold: to prevent lubricant from escaping and to stop the entry of contaminants that wear bearings and bushings. In dusty or wet environments, the oil seal is the first barrier.

To select an oil seal, the diameter alone is not enough: you must check the condition of the shaft, the roughness and hardness of the sealing surface, and the type of lubricant. A scratched or worn shaft means the lip does not seat properly and leaks. During installation, the oil seal is inserted perpendicular to the shaft, without striking the lip, and is lubricated before closing. If the housing has burrs or the shaft has play, it is best to correct it before installing the new part.

If part number 5341 is not the one you need, an equivalent can be looked up. For that, send us the measured shaft diameter, housing diameter and height, plus a photo of the old oil seal and the housing. With that data it is compared against the corresponding options and it is confirmed whether there is a direct replacement or whether adaptation is needed. It can also be cross-referenced by dimensions with other brands.
