The DBH 8870 radial shaft seal is a lip seal that is mounted in a component housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With dimensions of 17 mm shaft, 35 mm housing and 10 mm height, and Lx design, it is used in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales sells this brand and advises you so you choose the correct oil seal.

This item is a radial shaft seal from the DBH line, identified with the part number 8870. Its dimensions are 17 mm shaft diameter (d), 35 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. These dimensions are the ones you must verify against the shaft and housing before mounting, because any difference of tenths affects sealing.

Radial shaft seals of this size are found in equipment where a shaft rotates inside a housing: centrifugal pumps, electric motors, gear reducers, mixers, compressors and machine tools. They also appear in power transmission applications, such as gearboxes and conveyor rollers. The function is twofold: to prevent oil or grease from escaping and to stop the entry of contaminants that wear bearings and bushings.

To properly select an oil seal, in addition to the three dimensions, take into account the type of lubricant, the working temperature and the shaft speed. The Lx design is suitable for shafts with continuous rotary motion and present lubrication. During assembly, verify that the housing is clean and free of burrs, lubricate the lip before inserting it and avoid hitting it with sharp tools. If the shaft shows wear or grooves, the oil seal may not seal even if the dimensions match.

If you need an oil seal equivalent to the 8870, the most practical thing is to send us the full part number, the shaft, housing and height dimensions, and a photo of the old oil seal if you have one. With that data we can look for an alternative within the same DBH line or from another brand we sell. Not all equivalences are direct: sometimes the lip design or the material changes, and that affects performance.
