The DBH 8587Pol seal is a single-lip radial shaft seal designed for rotating shafts with a 55 mm diameter. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles that could damage bearings and bushings. It is press-fitted into a 78 mm housing and has a 12 mm height. It is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment operating with rotating shafts.

This DBH 8587Pol seal has an Lx-H-H design and is identified by its dimensions: 55.00 mm shaft diameter, 78.00 mm housing diameter and 12.00 mm height. The sealing lip is built to work on rotating shafts, with a spring that maintains contact pressure. The outer case is metallic, which facilitates press-fitting into machined housings. It is a component of the radial shaft seal and seal line that MR Accesorios Industriales sells DBH.

Typical applications for this seal include centrifugal pumps, electric motors, gearboxes, transmission shafts and continuous process equipment. In all cases, its function is to confine oil or grease and protect bearings from external contamination. It is also used in equipment exposed to dust or splashes, provided the peripheral shaft speed is compatible with the lip material. It is a wear part that should be replaced at every equipment teardown.

To correctly select this seal, verify that the shaft, housing and height dimensions match those of the machined housing. The shaft diameter must be within the recommended tolerance for radial shaft seals, and the surface must have adequate roughness to prevent premature leakage. During assembly, lubricate the lip and use an installation tool that does not damage the spring or the sealing edge. If the equipment operates at high speed or temperature, ask about variants with specific materials.

If you need an equivalent seal, you can send us the code engraved on the part, the dimensions measured with a caliper or a photo of the housing. At MR Accesorios Industriales we compare that data with the product pages of the manufacturers we sell to offer you the compatible alternative. We can also advise you on the lip type, material and spring according to the service conditions. Do not hesitate to ask about special sizes or alternative series.
