The DBH 5341 radial shaft seal is a lip seal that mounts in the housing and seals against 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 DBH brand radial shaft seal, identified by the code 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 body, not the material, which is confirmed against the manufacturer's data sheet at the time of quoting.

Seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft rotates 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 slow the entry of contaminants that wear down 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 mounting, 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 this before fitting the new part.

If code 5341 is not the one you need, a nearby size or an equivalent can be looked up. To do this, 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 available alternatives 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.

MR Accesorios Industriales sells the DBH brand as an official brand. If you already have code 5341 or the dimensions 43 x 56 x 6 mm, send it by WhatsApp and the quote is prepared. If you are unsure about the size, write to us anyway: with the shaft and housing data we can guide the search. For equipment with similar oil seals, it is advisable to also check the condition of the bearings and the lubricant.
