The DBH 5084 radial shaft seal is a lip seal mounted on the shaft and inside the housing to retain lubricant and exclude contaminants. Its dimensions are 20 mm shaft diameter, 40 mm housing diameter and 10 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and transmission equipment to protect bearings and gears. MR Accesorios Industriales supplies this brand and advises you on choosing the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified with part number 5084. According to the data sheet, it corresponds to a shaft diameter of 20 mm, a housing diameter of 40 mm and a height of 10 mm. The Lx design indicates a single-lip configuration with spring, suitable for retaining oil or grease under moderate rotation conditions. The elastomeric lip runs on the shaft and the outer diameter fits into the housing to achieve sealing.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, speed reducers and power transmission equipment. In all cases, its function is to prevent lubricant leaks and the ingress of dust, water or particles that accelerate wear on bearings and gears. It is also used on fan shafts, mixers and continuous process machinery where sealing reliability is critical.

To correctly install this seal, verify that the shaft measures 20 mm and the housing 40 mm, with a housing width compatible with the 10 mm height. The shaft surface must be free of burrs, scratches or excessive wear; a damaged shaft accelerates lip failure. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it directly. If the equipment operates at high peripheral speed or elevated temperatures, consult MR to evaluate the lip material.

If you need an equivalent seal, the most practical approach is to send us the part number 5084 or the current dimensions: shaft diameter, housing diameter and height. With that data we can look for alternatives within the same DBH brand or other brands we supply, respecting the design and lip type. We can also advise you if the housing accepts a seal with a different height or if it is better to switch to a design with a dust lip.
