The DBH 9491/85 oil seal is a lip seal designed to stop oil or grease from passing through rotating equipment. It mounts on a 23 mm shaft and fits into a 38 mm bore, with a height of 6.50/7.00 mm. Its A 219 design corresponds to a single lip profile with a spring, suitable for rotating shafts in pumps, motors, gearboxes and reducers. MR Accesorios Industriales carries this brand as part of its line of seals and oil seals.

This item is a radial shaft seal from the DBH line, identified with the designation 9491/85. Its standard dimensions are: shaft diameter 23 mm, housing diameter 38 mm and height 6.50/7.00 mm. The A 219 design defines a sealing lip with a metal spring, intended to retain lubricant and exclude contaminants on rotating shafts. The dual height (6.50/7.00 mm) allows some tolerance in the housing without losing fit. It is a common replacement part in industrial maintenance.

Typical applications for this oil seal include centrifugal pumps, electric motors, gearboxes, compressors and transmission equipment. It is found at shaft outputs where there is permanent lubrication and leaks must be prevented. It is also used in machine tools, process equipment and conveyor systems. Because of its compact size, it is common in low and medium power equipment operating at moderate speeds. The choice of lip and spring material depends on the fluid and the working temperature.

To install an oil seal such as the 9491/85, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip before inserting it and avoid striking it during installation. Concentricity between shaft and housing is key so the lip is not loaded to one side. If the shaft shows a deep groove, consider a wear sleeve or an alternative size. The allowable pressure and speed depend on the lip compound and the spring, data that is confirmed against the manufacturer's product page.
