For rotating shafts needing reliable sealing, the DBH 8587Pol radial shaft seal offers a 55 mm shaft diameter, 78 mm housing diameter, and 12 mm height. It keeps lubricant contained and blocks dust, water, and particles from reaching bearings and bushings. Press-fit into a 78 mm housing, it is a common replacement in pumps, motors, gearboxes, and power transmission equipment.

The DBH 8587Pol follows an Lx-H-H design. Its dimensions are shaft 55.00 mm, housing 78.00 mm, and height 12.00 mm. A spring-loaded lip maintains contact pressure on the rotating shaft, while the metallic outer case allows secure press-fitting into machined housings. This seal is part of the radial shaft seal and seal line available from MR Industrial Accessories.

Typical uses include centrifugal pumps, electric motors, gearboxes, transmission shafts, and continuous process equipment. In these applications, the seal confines oil or grease and shields bearings from external contamination. It also suits equipment exposed to dust or splashes when the peripheral shaft speed is compatible with the lip material. As a wear part, it should be replaced at every teardown.

When selecting this seal, confirm that the shaft, housing, and height dimensions match the machined housing. The shaft diameter must fall within the recommended tolerance for radial shaft seals, and the surface should have adequate roughness to prevent premature leakage. During assembly, lubricate the lip and use an installation tool that avoids damaging the spring or sealing edge. For high-speed or high-temperature operation, ask about variants with specific materials.

If you need an equivalent, send the code engraved on the part, dimensions measured with a caliper, or a photo of the housing. MR Industrial Accessories compares that data with the product pages of the manufacturers we supply to offer a compatible alternative. We can also advise on lip type, material, and spring based on service conditions. Ask about special sizes or alternative series.
