The DBH 8702 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. Its Kz design combines a sealing lip with a dust lip, so in addition to retaining the lubricant inside, it blocks dust and water from entering from outside. It is used in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates on bearings and the lubricant must be protected.

This seal is identified by its code 8702 and by the dimensions shown on the product page: shaft diameter 100 mm, housing diameter 123.80 mm and height 13.00 mm. The Kz design indicates a double-lip configuration: a primary sealing lip and a secondary exclusion lip, designed for environments with contaminants. The outer body is metallic and the sealing lip runs on the shaft with controlled interference to maintain contact without hindering rotation.

Typical applications for a seal of this size appear in equipment with large-section shafts: gearboxes and gear housings, centrifugal pumps, medium and high-power electric motors, and chain or belt drives where the shaft exits a lubricated crankcase. It is also found in road machinery, pumping equipment and process lines operating with exposure to dust, wash water or chips.

For proper installation, check that the shaft has no burrs or deep marks in the contact area: a new seal on a scratched shaft loses effectiveness quickly. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and seat the part straight, without striking the lip. If the housing has a shoulder or radius, respect the seating depth so the seal sits square. Operating speed and temperature depend on the lip material and the lubricant, so it is advisable to confirm them with the manufacturer's data sheet.

If you need a nearby size or an equivalent from another brand, send us code 8702 or the three dimensions (shaft, housing and height) and the type of service. With that we search the DBH line and the alternatives we carry. MR Accesorios Industriales sells this brand and can advise you on the Kz design versus other lip configurations according to the type of contaminant and the rotation regime.

To request a quote, write to us on WhatsApp with code 8702 and the quantity. If the seal is mounted on equipment that already has shaft wear, tell us that detail as well: sometimes it is worth evaluating a different shaft size or a more robust lip design. MR Accesorios Industriales works with radial seals and oil seals for replacement and maintenance, and will respond with the alternative that best fits.
