The DBH 5746 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. Its Lx design and standardized dimensions make it suitable for 85.73 mm shafts and 111.16 mm housings. It is used in gearboxes, pumps, electric motors and transmissions where preventing leaks and the ingress of dust or water is critical. MR Accesorios Industriales supplies this official brand and advises you so you can choose the correct seal for your application.

The DBH 5746 is a radial shaft seal with an Lx design, featuring a sealing lip and a stainless steel spring. Its dimensions are: shaft diameter 85.73 mm, housing diameter 111.16 mm and height 19.84 mm. The Lx design indicates a configuration with a main lip and an auxiliary dust lip, which improves protection against external particles. The lip elastomer is formulated to resist mineral oils and greases, and the spring maintains constant contact pressure on the shaft. It is a key part for sealing in rotating equipment.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In all these cases, the seal prevents lubricant loss and the entry of contaminants that accelerate wear on bearings and gears. It is also used in equipment in the food, chemical and petrochemical industries, where fluid containment is a priority. Its size makes it suitable for medium and large shafts, common in heavy machinery and production lines.

For installation, check that the shaft has no burrs or marks that could damage the lip, and lubricate the lip with the same service oil or grease before sliding it on. The housing must be clean and free of deformation; adequate surface roughness helps the seal seat correctly. When selecting a replacement, consider the shaft's peripheral speed, the operating temperature and the chemical compatibility of the elastomer with the fluid to be retained. If the original seal has a different design, consult MR to evaluate an equivalent alternative.
