The DBH 8870 radial shaft seal is a lip seal that is mounted in the housing of a component 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 bore and 10 mm height, and an Lx design, it is used in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH line, identified by part number 8870. According to the record, its dimensions are 17 mm shaft diameter (d), 35 mm housing bore diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. These are the dimensions you must verify against the shaft and housing before installing, 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, gearboxes, 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 down bearings and bushings.

To select a seal properly, in addition to the three dimensions, take into account the type of lubricant, the operating temperature and the shaft speed. The Lx design is suitable for shafts with continuous rotary motion and lubrication present. During installation, check 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 seal may not seal even if the dimensions match.

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