The DBH 5640 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 45.80 mm shaft diameter, 66.57 mm housing bore and 12.70 mm height make it suitable for equipment where space is limited and a reliable seal is required. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. MR Accesorios Industriales supplies this brand as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified by part number 5640. Its dimensions are 45.80 mm shaft diameter (d), 66.57 mm housing bore diameter (D) and 12.70 mm height (h). The Mr design corresponds to a standard single-lip configuration with spring, intended for rotating shafts. The sealing lip bears against the shaft and the outer diameter is press-fitted into the housing, creating a static and dynamic seal. The 12.70 mm height allows it to be fitted into shallow cavities without losing sealing effectiveness.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. In all cases, its function is to prevent oil or grease leaks and to block the entry of dust, water or particles that accelerate wear on bearings and gears. It is commonly found in industrial machinery, process equipment and vehicles where an economical, easy-to-replace seal is required. Its compact size makes it suitable for spaces where larger-section seals cannot be fitted.

To select this seal correctly, verify that the shaft and housing dimensions match those of the equipment. The shaft diameter must be within the recommended tolerance to prevent leaks or premature lip wear. The housing must have a suitable surface finish and sufficient depth to accommodate the 12.70 mm height. During installation, lubricate the lip and use an installation tool that does not damage the seal. Avoid striking the seal directly and make sure it sits perpendicular to the shaft.
