The DBH 5840 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 45 mm shaft diameter, 62 mm housing diameter and 8 mm height, it is press-fitted into the housing and runs against the shaft. It is a key part in gearboxes, pumps, electric motors and transmission equipment, where it prevents leaks and protects bearings. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH line, identified by part number 5840. Its standard dimensions are: shaft diameter (d) 45 mm, housing diameter (D) 62 mm and height (h) 8.00 mm. Design A 001 corresponds to a single-lip seal with spring, suitable for rotating lubricated shafts. The 5840 nomenclature follows the manufacturer's designation and allows it to be located quickly in the catalog. It is a standard replacement part, not a custom component.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the seal serves two functions: retaining the oil or grease inside the equipment and preventing the entry of dust, water or particles. It is also used on rollers and shafts of road, agricultural and industrial machinery. Its size of 45 x 62 x 8 mm makes it compatible with standard metric-series housings.

To install this seal correctly, verify that the shaft has the proper hardness and roughness, with no burrs or marks. Lubricate the lip with compatible grease before inserting it and install the seal with a mounting tube that presses on the outer edge, never on the lip. The 8 mm height should sit flush or slightly recessed in the housing. If the equipment operates with heavy vibration or temperature, consider a seal with an alternative material. MR can advise you based on your application.

If you need an equivalent or a nearby size, the most practical approach is to send us part number 5840 or your current dimensions (45 x 62 x 8 mm) by WhatsApp. With that data we can look for alternatives in other brands or lines we carry, always respecting the housing and shaft tolerances. We can also guide you if the original seal has any particular feature, such as a double lip or special material. Let's not improvise: the right selection prevents leaks and premature failures.
